Marris Chapters 3 & 4 Rewilding
Rewilding is a conservation project that involves reintroducing species to areas where they had been extinct, in hopes of creating an ecosystem like the one that existed there thousands of years ago. A closely connected idea that comes from rewilding, Pleistocene rewilding, involves the reintroduction of descendants of Pleistocene megafauna or similar species.
I don’t believe that this idea is practical or ethical. Rewilding is attempting to bring back an area back to the way it was thousands of years ago, but no one can be certain as to how it was that long ago and ecosystems constantly change over time. The Pleistocene megafauna became extinct a long time ago, and in their absence, ecosystems have evolved, so the reintroduction of large mammals can have many negative effects of an ecosystem. One of the things mentioned in the chapter was that death was very important in the rewilded areas and that carcasses can attract other species to the area. This however, may not necessarily be a good thing, as the attracted areas may not belong in and adapt to the ecosystem. Take for example, the black vulture from the French reintroduction program that was killed by a train. In addition, many of the species are long gone, so proxy species are being used, which can cause even more trouble. The proxy species might not be suitable substitutes and can become invasive and harm the species already there, possibly through disease, or other factors.
Donlan argues that large mammals are less likely than other species to become invasive and that “we killed ‘em once; we can kill ‘em again.” (69) This idea that we can introduce species to an area and just kill them if they become invasive is unethical and are humans trying to play god, which as mentioned in the book, is a big criticism of rewilding. Donlan argues that we already do that, and the leap is “admitting to ourselves that we live in an intensely managed world.” (68) Rewilding however, takes human interaction and control of nature to the extreme. We would be deciding where species live and which ones live and die and because many species are extinct and “proxies” are introduced instead, it seems like we are actually creating our own, new ecosystems.
Rewilding seeks to create an ecosystem like ones that existed thousands of years ago, before humans were around, but as Marris says, “the whole place is cultivated, man-made, created.” (70) It does not make sense to try to create ecosystems of the past when the outcome is unknown and can harm the ecosystems that exist today. We should just focus and preserving the nature we have now and learn to better treat and use the tools of nature all around us.
Rewilding – Marris Chapters 3 & 4
Emma Marris articulates the idea of “rewilding” in her book, Rambunctious Garden. According to her, “rewilding posits that the main factors necessary to keep ecosystems resilient and diverse are the regulation provided by large, top-of-the-food-chain predators; the room for these predators to do their work; and connections between predator ranges so they can meet, mate, and maintain a healthy diverse gene pool” (Marris 60). Essentially, it is a conservation endeavor to create prehistoric ecosystems devoid of human influence. Ecologists can observe ecosystems before humanity. This would be done by reintroducing particular species back into a specific environment. These species would be predators so that less room is made for “medium-sized predators like raccoons or snakes, who then expand and put significant pressure on little creatures such as songbirds” (60). As a result, there would be less instances of extinction.
Although rewilding seems like the ideal solution, it is not scientifically feasible or ethnically sound. The fact of the matter is that we, humans, have altered the entire world. According to Bill McKibben, “all we can do is make it less bad than it will otherwise be” (55). Marris also states that “there can never be any more of this kind of nature, because once touched by humans, it is ruined for eternity” (55). We can try to better our ecosystems, but we cannot reverse the damage.
Marris gives us examples – introducing cheetahs to Arizona or elephants to Missouri. These animals would be isolated from humans and carefully managed under fenced areas. I believe that the amount of scrutiny and intense management in these areas defeats the whole purpose of creating “pristine wilderness” through rewilding. This idea takes human intervention to a new level. In addition, these animals would be a threat to people who live in nearby towns and farms. Rewilding would make these places more dangerous. Furthermore, the ecosystems today have changed. Existing species have adapted and evolved from the past. Results of reintroducing these species would be unpredictable.
The idea of rewilding is unethical because humans are essentially deciding whether a species get to live or not. Marris points out an incident where Vera saw a weak and starving calf. He then called a member of the reserve to shoot it in an effort to end the calf’s misery (66). How can we be sure our decisions are correct? I believe it is not right to kill an animal just to put it out of misery. The right thing to do would be to feed it. And by reintroducing certain animals in particular areas, the other animals of the ecosystems would decrease in population. Moreover, Donlan says something very hypocritical and alarming. If an introduced species becomes invasive, “…we can kill ’em again” (65).
It is with no doubt that we live in a human dominated world. The battle of man versus nature cannot be solved with rewilding. If done so, we are disrupting existing ecosystems even more. Many ecologists believe that rewilding would yield beneficial results. In reality, it is hard to know. Hence, attempting to create ecosystems absent of human influence on today’s world would be unrealistic.
Rewilding
The idea of rewilding is one that is getting a lot of attention in the scientific and conservational community. Supporters of the theory believe that large predators were they key species of ecosystems. Large predators were they key because they kept the ecosystem in balance by eating smaller animals, which prevented the smaller animals from growing to too large a number and overeating plants. Since this was how ecosystems worked before humans intervened, rewilding suggests bringing large predators and other native animals back to ecosystems so they can restore the balance and bring the ecosystem back to its pristine state.
Many of the animals that lived in the pristine ecosystems are now extinct. Since conservationists cannot inhabit the land with the exact animals that lived in the past, they try inhabiting it with their evolutionary and sometimes domesticated counterparts. Instead of extinct wild horses, conservationists use modern domesticated horses. Instead of wild versions of cattle, conservationists use domesticated modern day cattle. The idea is that even though the animals are not exactly the same, they will hopefully play the same role in the ecosystem as their ancestors did.
There are a few problems with this theory. The first is that no scientist is sure what the ecosystem was exactly like before humans. In chapter 4 of Rambunctious Garden, there is a debate whether Europe used to be mostly forest or grassland, and if it was both, how often did natural forces cause the land to cycle between these two types of ecosystems. Conservationists may be forcing an ecosystem onto an area that never existed there before.
Another problem with rewilding is that introducing foreign species can have severe consequences. While conservationists would try to only introduce animals that are similar to animals have lived in the area before, the environment is not the same now as it was then. The animals in modern day may react differently to the ecosystem and can either die out quickly or become a huge invasive specie. While conservationists try to keep the change minimal, it is extremely hard to predict what exactly will happen when new animals are introduced into an area because there are so many different factors in play.
The last problem with rewilding is all the manpower that is put into the process. Humans have to pick out the animals to introduce into the ecosystem and monitor them to make sure they get off to a healthy start. Conservationists try very hard to create a part of nature that is like the way it was when it was human free. While rewilding might yield these results, the amount of human involvement in the process might defeat the whole purpose.
Marris Chapters 3 and 4 – Rewilding
In chapters three and four of Rambunctious Garden by Emma Marris, the concept of rewilding is extensively discussed. Rewilding is the process of reintroducing species to a particular ecosystem that they inhabited once before. The idea includes reintroducing predators to an area so they can regulate the food chain and maintain a diverse gene pool. Rewilding also involves relocating endangered species to ideal habitats to prevent extinction. Some proponents of rewilding support adding proxy species to certain ecosystems. These proxy species are close substitutes to extinct organisms that once lived in these ecosystems. People who support this view believe the proxy species will have the same effect on the ecosystems as their ancestors did. Another type of rewilding is Pleistocene rewilding. This type of rewilding was first proposed by Paul Martin and involves returning wilderness to the state it was in before any humans arrived. Martin goes as far as proposing to introduce proxy species of elephants, lions, and cheetahs to the reserves in the Great Plains to restore the ecosystems that once existed there. Of course, these views have been heavily criticized.
In my opinion, rewilding has many benefits, but it also can cause many problems. The problem with rewilding is that it is based on ideals. These ideals are uncertain to come to fruition in reality. For example, it is not definite that proxy species will interact with a certain ecosystem in the same way that their ancestors did. In fact, the proxy species might have adverse effects on the ecosystem. Rewilding is a relatively new concept that has only been tested on a small-scale. Although it has been effective in places such as Oostvardersplassen in the Netherlands, I do not know if it will be effective at a large-scale level. In order for it to be effective at a larger scale, it will require a tremendous amount of time, money, and regulation.
Another problem with rewilding is that it poses some safety issues. For example, if predators such as lions and cheetahs are introduced to reserves in the Great Plains, they can escape and terrorize Americans in the area. The goal of rewilding is to restore ecosystems to the way they were thousands of years ago. Unlike the pristine wilderness concept, which unsuccessfully tries to find land that has been untouched, rewilding allows people to create ecosystems that resemble the distant past. However, since species that have dominated the land have evolved to cope with the ecosystems they are currently a part of, rewilding might have adverse and unexpected effects. Therefore, it is not a good idea. I believe the only time rewilding should be utilized is when dealing with endangered species. If rewilding can help an endangered species prosper, then it will be beneficial. For example, it might be beneficial to relocate a species of endangered birds to an ecosystem that the ancestors of that species once inhabited if this will benefit the species.
Although rewilding is scientifically feasible, it would require an incredible amount of time, money, and regulation. Even if it is feasible, it is not certain to have the desired effects. Regardless, I do not believe that rewilding is ethically sound in most circumstances. Relocating species such as African lions, cheetahs, and elephants to foreign lands such as the Great Plains can harm the species. This is because they have adapted to life in Africa and their adaptations might not be well suited for foreign lands. Relocating these species to lands such as the Great Plains is also unethical to Americans in the surrounding areas because these wild animals can pose a threat to their livelihood. The only instance where I believe that rewilding is ethical is if it will benefit an endangered species that does not pose a serious threat to humans. It is quite clear from these chapters that rewilding is an interesting yet controversial concept.
Marris Chapters 3 and 4
In “Rambunctious Garden: Saving Nature in a Post Wild World” Marris talks quite a bit about the prospects of rewilding in chapters three and four, however before I get into what she said about it, first I’m going to give a small explanation as to what it is. Rewilding as I understood in the text, basically is the idea of taking a particular type of species from one environment and putting it in a new environment; more specifically an environment where an animal relating to the ‘new’ animal has gone extinct or is no longer around. The reason they want to do this is to keep a little bit of nature pure to make it ‘wild’ again; to the extent where it looks like it did before humans interacted with it.
Now technically rewilding is scientifically feasible for a few reasons. The first reason is because scientist don’t have to worry about the fact that nature has changed since a few thousand years ago and that it has been affected by man, since nature changes regardless of man’s presence or not. Furthermore in order for them to make a certain environment ‘wild’ again they would have to do what the book says and release top of the food chain predators. By releasing these types of predators into said environment it will cause greater competition amongst the other species. By this I mean there will be more intra-species competition that they will have to avoid being eaten and it will lead to survival of the fittest and better the species in general. Furthermore, it will decrease the amount of food competition, which allows one certain type of species to consistently eat a plant it likes and it will lead to fewer species entirely. However, bureaucratically it is not possible for rewilding to occur. For one thing there is always people who are unwilling to give up land at could just become another debate of conservationism versus people who don’t care about nature. Secondly, there is another problem which the book mentioned regarding racism where sending African animals to the United States might prove problematic mainly because the citizens of the United States might not want to live with African animals and this might look like racism which isn’t a good thing.
Rewilding might also help nature in general by preventing extinction because if animals are dying out due to human interaction, by placing them in these secluded environments they may have a better chance of survival. However, in my opinion though, we should not do rewilding because for one thing it is almost like “we are playing god,” as the book says. The book answers this by saying we are influencing nature regardless so what the difference. The difference is that this approach of rewilding is much more direct. Furthermore by adding a species to a new environment we might be creating invasive species that might end up ruining the environment and it’s not like that hasn’t happened before. So, to conclude whilst rewilding does have its perks, all in all I think it is a bad idea.
Marris Chapters 3&4
According to Marris, rewilding is essentially returning an area back to the state it would be in today if there were no humans. Although the intentions of rewilding are good, the idea of undoing the changed that humans have caused, the reality of creating such an environment is impossible and unrealistic, not to mention contradictory and unethical.
Firstly, creating recreating ecosystems that existed before humans existed in many cases is completely impossible. Since thousands of years have passed, the species that once existed during the Pleistocene may have evolved. If a species has been exposed to a different environment, they may have changed the way they behave. Though the species is the same as the past, its role and the way it interacts with the environment may have changed. Another common problem is that many of the animals that existed during the Pleistocene have since then become extinct. In order to overcome this, ecologists might introduce a similar species that would play the same role as that of the extinct species in the ecosystem. For example, introducing “Bactrian camels (from the Gobi Desert)” to America to replace the wild horses and camels that used to exist here (Marris 63). No matter how hard humans try, some ecosystems can never be replicated exactly, just approximately. Reintroducing animals also leads to many shifts in the ecosystem. According to field ecologist Josh Donlan, after the reintroduction of wolves to Yellowstone, “not six month goes by without a new groundbreaking paper… linking some unexpected ecosystem shift” (Marris 62). It is clear that bringing in a single species can drastically alter an ecosystem since the ecosystem would adjust to accommodate the changes. Changes to the ecosystem would also affect humans since the rewilded animals need to be separated from humans and managed carefully. In some areas, towns and farms would need to think about putting up fences to protect themselves from the new large beasts. Though these changes are not impossible, they create great difficulties for humans and could potentially create a great threat if they were not carried out. Recreating ecosystems from the past prove to be troublesome, difficult and scientifically impossible due to the state the world is today.
Rewilding aims to take away human interference with the environment, but by actively taking a hand in recreating environments, rewilding actually does the complete opposite of its purpose. Rewilding is self-contradictory and unethical. One of the criticisms of rewilding that Donlan points out is the idea of “playing god” (Marris 65). Although both introducing and removing species may be considered “playing god,” actually having to ship in animals to different ecosystems altering the ecosystem in a different way. Nature will always readjust itself to the given conditions, but since human effort is needed to maintain such an environment, it is no less natural than its current state. An artificially created environment, no matter how realistic it is, is no substitute for the real thing. The intentions of the ecologists are admirable, but completely misguided.
Marris Chapters 1 & 2
In the opening chapters of Rambunctious Garden Emma Marris introduced us to the general idea of nature that is held by most and how it has come to be this great paradox. Firstly Marris delves into the idea of the “pristine wilderness”(3), explaining the generalized concept of natural world that is the essence of life untouched or not manipulated by humans.
The appreciation of nature has been one that cherished the earth’s still truly wild habitats in comparison to the great landscapes that have been resurfaced by humans. However, Marris throws away this ideal of nature blatantly stating that all of earth’s habitats in one way or another have been affected by human presence on earth. Thus, when appreciating nature we must not only look to the vast tracts of wild life to satisfy our desire to connect with plant/ animal life we can also find joy in acknowledging natures presence in our more urban areas such as city parks and community gardens, even the plots of grass on the sidewalk. Marris emphasizes the point that there is life around us even if it is not as grand as what we picture in our minds.
After highlighting the inaccuracies we use to define nature, Marris then goes further to prove how paradoxical such ideals are by addressing the efforts of conservation with the use of often-unobtainable baselines as a goal. As a case study, Marris references the Hawaiian Military Reservation that she visited in 2009. Hawaii has more non-native plant and animal species than not. This is due to western influence and takeover throughout its history. Scientists used a tract of land at the reservation to determine whether native species would be able to thrive again if non-natives were removed. However, this attempt proved disappointing. With slow if any regrowth, this 5-year experiment proved that such attempts to return an ecosystem back to a baseline before certain human influences are done in vain.
With this Marris brings up a split view of nature. Certain ecologists believe that nature is only true wilderness if it has not been tampered with. However, others believe that nature should be seen as all natural things in an ecosystem- whether they were originally there or not. There is also the ultimate paradox that supports this second view. In order to return nature to its previous state- before human alteration- humans must alter the nature that exists. And so, whether constructed or not, the land will have still been manipulated by humans.
I find Emma Marris’ points to be very interesting and logical in her argument against the idea of pristine wilderness. I personally try to connect with nature wherever it may be. This is not to say I don’t also believe in the concept of the great out doors- pristine and far away. Growing up in the city, where vast landscapes are scarce it is easier to follow Marris’ concept. I think her points are valid because the changes that have been made to the earth are so drastic that even if we were able to recreate a past life in the history of the earths ecology it would not be authentic or without much human manipulation.

Looking at the number, Brooklyn has the highest number of high school students consuming alcohol among the five boroughs in 2009. By percentage, Staten Island has the highest number indicating that about 38% of all high school students in Staten Island had at least one alcoholic beverage in the 30days from when the survey was taken. But by number, 38% translates to only 5,000 because Staten Island is lowly populated.
I’m a bit surprised by these results. I thought heaving drinking in adults in high poverty neighborhoods would be the highest in all the years but my hypothesis was wrong. There seems to be a relatively little correlation between poverty and heavy drinking. In year 2003, percent of heavy drinking in neighborhood with high poverty was the highest (5%) but it was the lowest in year 2007 (3.8%). However, it does seem like the percentage of heavy drinking in medium poverty neighborhood is usually the lowest among the three poverty levels.
Observation from the scatterplot indicates that binge drinking in adults increase as access of alcohol in service outlets increased. Majority of binge drinking in adults remain at about 13% until about 200 service outlets available but from 1,000 to 1,200, percentage shoots up to about 36%.
This graph compares binge drinking in New York City by age. The percent of adults and high school students binge drinking throughout all years recorded in the graph (2003-2010) is similar, both remaining around 15%. From about 2005 to 2007, percentage of adult binge drinking was slightly higher than that of high school students. The graph also indicates that binge drinking did not decrease in all ages throughout New York City.
The red areas indicate the neighborhoods with the highest binge drinking percentage of 18%-3.5%. From the map, we can conclude that the binge drinking rates in Queens and parts of Long Island are relatively low. Astoria, Greenpoint, Fordam (Bronx),Union Square, Chelsea, as well as Upper East Side and Upper West Side show the highest adult binge drinking percentages. This makes sense because there is a greater access to alcohol in many of the areas mentioned above.
The Debate on Rewilding
In Rambunctious Garden, Emma Marris spends some time talking about the concept of rewilding. People who believe in rewilding, adhere to the belief that a truly real and “positive” version of nature is one that was present well before humans took a stranglehold on the earth’s resources. This means that ecosystems should be restored to the state they were in over 10,000 years ago. An example of an environment these “rewildists” are looking to “restore” is the Great Plains are of the United States. They hope to reintroduce species that are similar to those living there in the pre-human era. For the most part, the focus is on major carnivores and those at the top of the food chain. A major conviction in rewildists is that top predators are what keep the food chain and the ecosystem as a whole balanced. Their hunting keeps all other populations in the environment in check and at healthy numbers. This means that in a future with rewilding, there may be lions and cheetahs roaming the American Great Plains.
In my opinion, I do not think rewilding is such a beneficial thing to do. There are various problems that surround the issue as well as some counterintuitive ideas. Firstly, this whole process would be extremely costly. Animals from other continents would have to be shipped over to the United States and then secured in fenced off areas. These areas would have to be monitored by peopled hired to do that. If the process had any real payoff I would see no problem in spending the money but I do not think the pros outweigh the cons. I do not see how such a human controlled environment can be seen as truly “wild”. Conservationists who hold true to rewilding are basically saying that they can build a form of nature that is more wild and untouched than nature can itself. I feel that the methods of rewilding are counterintuitive to the goals they are setting. By bringing in animals from around the world, you are influencing the environment stronger than any passive human action could. “Building” an ecosystem is equivalent to building a mall in my book. The ecosystem wouldn’t be a naturally occurring phenomenon but a man-made wonder that is supposed to look untouched and ancient.
I do not adhere to the belief that true nature must be pristine and virgin to be worthwhile. I like to think that every living organism from a bush deep in a forest to a tree on a busy city street is a part of the global spectrum of nature and thus should be respected. By focusing on these smaller plots of undeveloped land, we in a sense forget the organisms who do not live in these areas and have to deal with human interaction all the time. I just think that we as a species should accept the fact that nature has had to adapt to our development. We shouldn’t think of ways to “restore” nature to a prehuman state but rather find ways to keep what nature we have now alive and well.
Rewilding: A Foreseeable Future.
Concept of rewilding Rewilding simply means conservation what existed prior: “the pristine wilderness.” The Białowieża forest experienced its own rewilding because the forest often became “a game preserve for royals and other elites” (Marris). The first instance of human influence began in 1409 with “Władysław Jagiełło, king of Poland and Lithuania” (Marris) who hunted game for his army to fight off the Teutonic Knights. Under 19th century Russian rule, humans killed off some bears and wolves that competed with them for game. In World War I, Germans logged over 5% of the forest and hunted the bison aggressively, lowering their numbers significantly. Rewiliding seems to be the only solution in minimizing human damage upon the great wilderness, restoring nature back to their baselines, but under what guidelines?
Rewilding began under Hermann Göring as a personal conquest for bison, deer and boar. However, this transformed quickly as he “ordered the game protected and local people expelled from the forest villages and murdered in large numbers” (Marris). The idea that the wilderness contained a limited amount of resources always existed and ironically, people always ended up rewilding the wilderness by accident, restoring a certain level of pre-existing biodiversity.
The director of the University of Warsaw’s Geobotanical Station, Bogdan Jaroszewicz finds a certain wonder with the “aura of the forest” (Marris) something innate within each of us that is able to connect to the great wilderness. While nature isn’t conducive to human progress and development, it remains a place humans can seek solace and reconnect to their origins. Athough efforts of rewilding may be generally beneficial, the same can be said for the counterargument. “Megafauna” such as the wild horses, mammoths, mastodons, ground sloths, glyptodont, short faced bears, camels, sabre-tooth tigers, lions and cheetahs from prehistoric eras died off because of their inefficient calories consumption. They consumed too many calories and over the long period of time, it become impossible for the environment to sustain such gigantic consumers. It’s ridiculous to try to revisit this baseline because at some point in time, these creatures were dominant members of this ecosystem. One of Marris’ ideas states that nature constantly changes and morphs to accomodate the inhabitants.
Yet the feasibility exists. Some of the “North American groups used fire to clear areas to promote new green growth” (Marris), attracting all sorts of game. Australians also utilized fire to bend nature and rejuvenate it. For example, they used fire to clear paths for travel, encourage plant growth, and attract herbivores for game. If our ancestors understood the methods for rebuilding the environment, why can’t we recreate that phenomenon?
Dave Foreman, an environmental activist promotes a purist view of preservation, insisting that nature should be devoid of people. (Ironically, the man who appreciate nature exclaims that man should not be in it) One quote from Aldo Leopold, an American author and environmentalist states, “one of the penalties of an ecological education is that one lives alone in a world of wounds” (Marris). These radical environmental activists do not realize that the costs for rewilding may be greater for some areas than others and definitely can be realized. However, reasonable goals must be set in order for humankind in order to reach them. Harmony between humans and nature exists nonetheless. Nature is whatever exists and adapts to the current ecosystem.
Post 9/9/12: Rambunctious Garden 3, 4
The concept of rewilding is a very radical and grandiose idea. Specifically Pleistocene rewilding, the idea of recreating ancient, pre-human ecosystems (before even native human inhabitants) using existing species as proxies is an incredible project. To be fair, if the natural processes it hopes to promote occurs as intended (or, even if unintended, sufficiently nature-like), then the rewilding project that Donlan, Vera and others hope to implement would probably be less labor-intensive and cheaper than most preservation techniques. The idea of Pleistocene rewilding is nothing short of absurd, since it would require the transport of many species across continents to create, as Marris puts it, an imperfect replica of the environment it hopes to be. Some species, like elephants, which emulate the massive herbivores in past North American ecosystems, would be an undoubtedly peculiar sight, while others, like cougars, which proxy for carnivorous predators, frighten opponents at the prospect of living near such dangerous animals.
The benefit of the concept of rewilding is that it promotes the concept of an imperfect and non-“pristine” nature. In contrast to preservationists, it requires human interference to at least initiate and catalyze the process of creating nature. Also unlike preservationists, who hope to save the lives of flora and fauna alike, rewilding, at least in the eyes of Frans Vera of the nature reserve Oostvaardersplassen, also includes death as a natural process (death meaning corpses of animals and the like, notably absent from many Yellowstone postcards). Furthermore, rewilding promotes a cycling and changing ecosystem, of plains and shrubs and forests, of population shifts of predators and prey. Rewilding may very well be the last thing from a conservationist’s idealistic vision, but it does seem like a practical vision.
On the flip side, rewilding as an idea is too rural or nature oriented. The ideas put forth by Marris, her colleagues and travel associates focus very much on reforming preexisting natural terrain; they do not consider urban settings. This does give pause for some concern; from rural towns to urban metropolises, few would truly appreciate the notion of rampaging pachyderms or growling carnivores at their doorstep. In those cases, the damage caused by nature may well overshadow the cost-saving intention of rewilding, especially in the long-term. Plus, while the idea of returning to a Pleistocene era would be an attractive baseline to reach, it may not be entirely practical with regards to the changing global ecosystem. Marris and her researchers did study about repositioning tortoises to proxy in certain archipelagic systems, but the reports of the species that the tortoises replaced were extinct for a few centuries; the Pleistocene rewilding scheme hopes to predate millennia of change, humans or otherwise. There will be unintended consequences to rewilding, no doubt about it. Marris does note that success or failure, such a project would provide valuable information. Where the line between in control and out of control of the situation is the question of this ambitious idea.
In all, Marris and her scientists do have a case for rewilding, even for Pleistocene rewilding. However, I believe that it should be done in small and moderate scales; a series of mountains, or large plains, would be an appropriate setting for rewilding, but entire continents should not be redecorated for the sake of nature. I would doubt that neither the animals nor plants nor humans could beneficially survive such a radical transition. Rewilding works, to some extent; it just needs a bit more time to refine.

- In 2010, Brooklyn (1,621), followed by Queens (860) and the Bronx (752), had the most carbon monoxide incidents. Manhattan,however, had the highest rate per 100,000 buildings (12.2%) of carbon monoxide incidents in 2010. Queens (2.2%) and Staten Island (2.3%) had the lowest rates of incidents per 1,000 buildings in 2010.
2. In the graph below, the medium level of poverty does not always correspond with the middle number of carbon monoxide incidents. The highest level of poverty, however, does correspond with the highest level of carbon monoxide incidents but the lower levels and medium levels of poverty do not always follow the anticipated pattern that the higher the level of poverty, the higher the number of carbon monoxide incidents.
3. The correlation between the percent of households rated good or excellent with the number of carbon monoxide incidents suggests that the better quality of the housing structure, the less carbon monoxide incidents occur. Perhaps the better quality housing and neighborhood structure and appliances (such as the furnace), the smaller the chance of carbon monoxide incidents occurring.
4. From 2004 to 2005, all boroughs experienced an increase in the number of carbon monoxide incidents. Staten Island experienced a less significant increase than the other boroughs from 2004 to 2005 and then appears to have remained rather stable. After their increase in 2004-2005, the other boroughs appeared to have gradually decreased until another gradual increase in 2008. The carbon monoxide incident levels appear to be at a slightly higher level in 2010 than in 2004 (most notable difference in Brooklyn).
5. Rate of carbon monoxide incidents per 1,000 buildings appear to increase the more north one travels on Manhattan and then gradually decrease the more north one gets in the Bronx. Staten Island had a low number of incidents (light yellow). Queens also had a low number of incidents, with the largest being in the middle of queens (more orange than surrounding areas).

On the surface, rewilding sounds like a fantastic idea. Through rewilding, ecologists can study a natural environment free from human interactions. They can also examine how different species interact before the arrival of humans. However, rewilding is not very feasible and it is quite unethical.
According to Dave Foreman, the concept of rewilding comes directly from the food chain of the ecosystems. At the top of the food chain, the predators regulate the population of the other species. If there are fewer predators, the population of the other species decreases. This results into an overpopulation of some species and an extinction of other species. Marris summarizes this by saying that the ecosystem will end up with “fewer species” (60). By reintroducing species into an environment, ecologists hope to restore “evolutionary and ecological potential to populations of large animals… and to inspire people to support nature conservation” (62). It would also prevent the extinction of certain species.
The main problem with rewilding is that it is almost impossible to replicate nature into an environment that existed thousands of years ago. Dustin Rubenstein points out that “placing proxy animals in a modern landscape could spell trouble” (65). These animals could generate unpredictable results and it could lead to an environment far from the past natural landscape. Furthermore, humans already touched this land thousands of years ago. In Chapter 3, Marris states that many people do not include the early humans because they are not considered “civilized.” However, Marris argues that “first people might have made greater changes to the landscape than the European arrivals ever did” (43). In fact, many large animals died because of the hunters from these early humans. Recreating a landscape with these large animals without the human hunters is arguably not a faithful representation of the environment in the past. Since we cannot recreate this environment, we are essentially observing a completely new environment.
In addition, rewilding is not very ethical. Despite what Donlan said, we are basically playing god since we can pick and choose which species can live and which species can die. In this case, we are basically picking and moving those species that we are interested in studying. Once the species are moved into the new environment, we give the species what it needs to survive. In addition, we can kill off an animal if we want to. In Chapter 4, Vera “called one of the reserve’s staff members to come and shoot [an abandoned calf].” Apparently, “[letting] an animal starve to death is too cruel to be allowed, even in the name of nature” (66). The fact that humans can control life and death of different species through rewilding makes it quite unethical.
Even though humans can create a landscape that looks “natural” to many people, it is not necessarily an ideal environment for studying the past. As Marris points out, “the whole place is cultivated, man-made, created” (70). The fact that it is man-made reinforces the idea that there is no baseline or pristine wilderness. Instead of recreating the past, these ecologists should just focus on the environment of the future. We can start by building a relationship between human and nature instead of separating it.

This is a graph of the Overweight or Obesity of youths by Borough in 2009. According to the survey, an observation that can be made is that the percentage of overweight youth is only 27.3%. This is not to say that this is a low number, but I personally thought it would be a larger percentage. Another observation is that, strangely enough, all the boroughs do not have a large difference in the percentage rates of overweight or obese youths.
This is a graph that shows the obesity of adults based on neighborhoods. Its strange that the median of obese adults tend to rise as poverty increases. Also, observation shows that as time progressed, obesity generally increased as well.
This is a graph about the Neighborhood Obesity of Adults by Physical Activity of Adults. Observation tells us that physical activity has increased as obesity has decreased based on the scattered dots of each borough. Majority of the dots are focused around the 60-70% although the percentage of obesity ranges from 10-40%.
This is a graph of Trends in Obesity of adults based on years. Observation tells us that Brooklyn maintains the highest amount of obese adults. It can also be noted that none of the lines show an immense increase or decrease in trends in obesity at first glance, however the variable of interest over time doesn’t reflect much change in a graphical form. Instead, small rise or falls show great increase or decrease in numbers of obesity.
This is a graph showing the obesity of adults by neighborhood. The graph provides a sectioned off view of each individual area in the five boroughs. Despite Queens being a large geographical area, the maroon colored areas are rare in the borough. Also, Manhattan being a smaller area generally also has a lower percentage. The Bronx tends to have more of this maroon colored percentage including Brooklyn and Staten Island.
Rambunctious Garden Chapters 3 & 4: A Critical Responce to Rewilding
Rewilding, according to Marris’ book, is described as a conservation effort aimed at designing or redesigning brand new ecosystems, focusing less on what the area would have looked like had humans never stepped foot on it, but more on what it looked like even further into the past. Because of all the animals that have since gone extinct, ecologists would use “proxies” for those lost species, animals taken out of other habitats and put into these new ones the essentially play the role of the extinct species.
Not surprisingly, the idea is quite controversial, and in my opinion, pretty hypocritical coming from ecologists who constantly argue that humans have degraded nature by interfering with it too much. This idea of “rewilding” takes the concept of human intervention to the extreme, with humans essentially engineering and creating their own ecosystems. As one of the critics cited in Marris’ book says about the idea, it has humans playing god, which we have no right to do.
Additionally, aside from the questionable ethics that come along with this idea, there are also a number of scientific and logical questions that arise. As ecologist Josh Donlan pointed out in Rambunctious Garden, nobody was around to document how the ecosystems shifted back then as a result of the extinction of various large species that advocates of rewilding want to re-introduce or simulate (page 66). Similarly, we have no way of knowing what would happen if we were to introduce these “proxies” again, and it is very possible that negative side effects could arise that we would not be prepared to deal with. For example, they could result in the arrival of invasive pests or even themselves become invasive to the habitat they are introduced to. Furthermore, the program’s advocates’ response to those claims, saying “we killed ‘em once, we can kill ‘em again” (page 69), is very insensitive and unprincipled, especially coming from an ecological point of view.
While I support and agree with the idea that is it a futile task to try to preserve nature as it was before humans interfered, I think it is just as fruitless to take it one step back and try to emulate even older ecosystems, especially by interfering with existing ones. Doing so only pushes the divide between humans and nature further apart, since it is highly unlikely that humans will live in areas where the giant carnivores Marris talks about in her chapter will be introduced and it is just as unlikely that those carnivores will live in areas inhabited by humans. The answer to the question of how to preserve nature in this human-dominated and ever-changing world may still not be fully known, but I definitely think that engineering our ecosystems is not that answer we are looking for.
Rewilding Revelation
I understand that ecologists and scientists of the like would be interested in recreating ecosystems that mimic those of 13,000 years ago, but I do not agree with or understand why they would want to do this on a large scale in America. Marris tells us, “The idea is to restore long-lost processes such as intensive grazing or population control by large predators, to restore ‘evolutionary and ecological potential’ to populations of large animals just barely hanging on in their current ranges, and to inspire people to support nature conservation” (62). In my opinion, rewilding is taking conservation and research to an extreme and negatively effects present-day environments. While reading through these chapters, I found myself thinking those ecologists taking part in rewilding schemes are somewhat selfish. Vera strives to recreate a “natural-processes-driven landscape,” claiming that a “natural ecosystem is better than a cultivated one.” The irony, as Marris states, is that “the whole place is cultivated, man-made, created” (70).
Rewilding, as coined by Dave Foreman in the mid-1990s, is the idea that the resilience and diversity of an ecosystem is based on the regulation by large, top-of-the-food-chain predators (60). I understand the idea of a species being squeezed out by others, in the absence of predator regulation, but I do not agree with Vera, or any person, “playing God”–though he claims that isn’t true. It seems silly that he’s picking and choosing certain animals or species that kind-of-sort-of work as those who may have been in that untouched environment years ago. Not only is Vera, and other scientists involved in rewilding initiatives, trying to cast present-day animals as ancient megafauna, but he is taking those animals out of their current natural habitats and relocating to new environments assuming they’ll be good fits. This proves to be a serious issue when death has become a prominent component of rewilding. Sure, death is a major component of any ecosystem, but rewilding projects and “pristine” areas like Bialowieza in Poland are either attracting or implementing species into unfamiliar territories. That rare black vulture from the French reintroduction program would never had died had it not been attracted to the carcasses nearby and not been unaccustomed to the proximity to or danger of the train tracks it perched on.
“What about bringing cheetahs to Arizona or elephants to Missouri to play the parts of related megafauna?” (61). Well, not only are the Arizona or Missouri environments unfamiliar to those species, but the current conditions of those ecosystems, not to mention the current human population, might not bode well with those animals living on the land. Similarly, Donlan deciding that the species of large tortoises were better off being translocated to islands seems selfish to me–“[he] finds them to be an ideal candidate for testing out the rewilding idea” (66). Not only is there the issue of some animals possibly being unable to adapt in new environments, but Marris has told us more than once now that nature does not need human involvement. The dynamic of environments, whether that be 13,000 years ago or present-day, may be very different but all are results of natural evolution, not man-made change. Vera’s project “looks to the past, but creates an unprecedented ecosystem” (68).
“Rewilding”
Emma Marris introduces the debated idea of rewilding nature in chapters 3 and 4, a topic I have mixed opinions about. Although the general notion behind the idea seems both logical and optimistic, I fear that it is difficult to achieve in large scale and can have unforeseen consequences.
I agree with Josh Donlan, an ecologist, that the opposition against this idea should not solely be fueled by the dislike of humans managing nature. This critique is not specific to the idea of rewilding. He says that it is imperative we start “admitting to ourselves that we live in an intensely managed world” (64) and perhaps this is a healthier impact humans can have on the environment as it seems to be a way that man can work with nature. Although I understand why many oppose this idea and I also dislike the idea of humans managing nature, I do not believe this should be the sole platform on which the opposing opinion specific to rewilding is formed. I appreciate Donlan’s optimistic attitude towards the end of chapter 3, stating “we can make things on Earth better, not just less bad” (56). We must keep this optimistic attitude and do all we can to refrain from being idle and stagnant. Although rewilding may not be the ideal or perfect solution, it is more proactive than giving up and not embracing nature.
When we consider the idea of rewilding, I think it is imperative for us to pose a few questions that will determine if the process is a good fit for the area. Such questions might include: Is this process sustainable and feasible? What effect will it have on the environment, its species, as well as the people that inhabit nearby land? If we are successful at carrying out this process on a small scale, we could then move forward to see if the plan can be executed on a widespread, larger scale.
Aside from perhaps the financial or timing aspects, the ideas brought up by Frans Vera appear logical if carried out successfully. Essential processes such as “intensive grazing” and “population control” (62) would be facilitated, which could in turn have significant positive effects on the ecosystem. Vera’s suggestion of using rewilding as support for the necessary cycles that change land from forests to shrubs and grassland is logical. To see the impact of this process and determine its feasibility on an area of land, one would have to examine and study it for a long time.
Although the aforementioned effects of rewilding appear promising, there are a few possible downsides to the process. One such fear is the introduction of dangerous animals to habitats and the “threat of death” (64) to areas that are not accustomed to such “dangerous carnivores” (64). Another uncertainty regarding this process is brought up by ecologist Dustin Rubenstein who says “proxy animals…could become invasive pests, or escape their parks and cause trouble with local landowners” (65). I also understand this critique as Rubenstein explains “these ecosystems have changed” and “attempting to fill gaps that closed long ago with proxy animals could generate unpredictable results” (65). Prior to carrying out this process, we would need to be certain regarding the possible behaviors of these animals when introduced to a new environment.
Regarding the future of the environment and its precious species, it is often easier to be critical and harder to make feasible and practical suggestions. It is therefore important that we consider all options and thoroughly examine the respective pros and cons before coming to decisive conclusions.
Manal’s post of Ch 1+2
In Emma Marris’ “Rambunctious Garden” she offers a more contemporary view of nature and its relationship with humans. She believes that the eighteenth and nineteenth century quest to conserve “pristine” nature is outdated because there is no such thing as unchanged nature. Ecosystems have undergone many changes both “anthropogenic” and not. In the first two chapters of Marris’ novel she explains why the manner in which nature was viewed in the eighteenth and nineteenth centuries is an outdated approach.
Marris explains that in society we are conditioned to believe that nature is “distant, wild, and free” with no human interference (Marris 1). However, she offers a new outlook on conservation, which she dubbed the “rambunctious garden” (2). According to Marris, the rambunctious garden is a “hybrid of wild nature and human management.” Rather than preserving a large plot of land where no people live, she believes that conservation should be intertwined with cities, or places with a high concentration of people. Marris stresses that the “rambunctious garden is everywhere” and does not have to be a large open space (2). She gives examples of “strips of land attached to rest stops” and “city traffic circles” as rambunctious gardens. In order to do so, she explains that society’s view of what constitutes nature must change.
In society, the idea surrounding nature is that it must be a “stable, pristine wilderness” (3). When nature is preserved it is done so according to a “baseline,” which is how the land was believed to have looked like before the influence of people (5). However, this becomes very tricky because nature undergoes many changes over the years be it “anthropogenic” or through a natural occurrence ie volcanic explosion. Furthermore, preserving nature according to the baseline poses potential problems, because species and humans who were living on the land are in most cases forcefully expelled. For example, in the Scotia Sanctuary, the rabbits and foxes were deliberately poisoned because they were viewed as a “threat” to the species already in the Sanctuary. I agree with the author’s position that preserving nature according to a baseline is not the most effective way for land conservation because it becomes difficult to decide what makes nature “pristine.” Also given the large amount of people who live in the cities, it is crucial that nature is included as part of their daily lives rather than something that is “distant.”
Furthermore, Marris also describes the historical transition of the connotation behind nature. In the 1860’s literary Romantics like Henry David Thoreau and Percy Shelley praised nature as “the stuff of life” (18). It was a place where people can be in solitude, which means that nobody can live there permanently. Consequently, this is also the time when the Miwok Indians were forcefully removed from Yellowstone because of the belief that there should be no people living in the park. However, towards the end of the nineteenth century, ecologists began to research how nature itself changes and achieves stability. For example, Australia over the millennia has drifted towards the north, but the overall global climate was cooling so it managed to reach a “stable climate” (33). All in all, ecosystems are always changing be it “anthropogenic” or by nature, and according to Marris, it is ultimately impossible to find an unchanged ecosystem to preserve. Ultimately, the only feasible solution for the twenty-first century is to create a “rambunctious garden.”
Post 9/5/12: Rambunctious Garden 1, 2
In the first chapters of Emma Marris’ Rambunctious Garden, she quickly indicates—and likely will continue to reinforce in later chapters—the problem with many conservation projects: it is just not that simple. Preservation is not as easy as planting a tree or making compost to save the environment, although many people—especially city dwellers and commuters, I would haphazardly guess—see it this way. While it does serve to be environmentally friendly and, indeed, help nature in at least reversing more obvious, destructive consequences of nature, such as the dramatic increase in carbon concentration in the atmosphere, it does not, say, save the sequoias, at least not in a direct sense. But Marris brings up a good point: should it?
As evident in chapters 1 and 2, preserving such majesties is often incredibly costly, either at the cost of labor or of the surrounding nonnative species, as was in Marris’ Hawaii example, or, more often, both. In the Yellowstone model, the conservationists sought and seek an arbitrary baseline—typically pre-European settlement—as their guideline of what natural utopia should be. The problem, as Marris points out, is that nature is never still, never static. Evolution, slow though it may be, works to alter the flora and fauna (and, indirectly, the landscape as well). Migratory patterns of plants over the last several glaciations also indicate no… well, pattern; the distribution of seeds over a vast continent went in different directions, sometimes defying logical progression of post-glacial distribution. Would it not be, then, that we are preserving a false ideal of what we believe nature should be?
The concept of having nature for various reasons began (in the States) in the Northeast, where Thoreau and Emerson could seek peace and aestheticism from the scenery—often little more than a mile or two away from civilization. Muir expanded upon that with a more zealous approach to nature, attributing it to godly proportions. Teddy Roosevelt had a more violent take on nature—that from animals to minerals, it was for our taking—but nevertheless emphasized its necessity, if even just for sport. I am unsure which of the reasons would be preferable (though I would prefer Roosevelt’s gung-ho style), but regardless, as nature diminished to towns, cities and metropolises, awareness to its ebb increased.
Nevertheless, conservationists have created some havens—if only very small relative to the grand scheme of things. A patch of native Hawaiian plants here, a pocket of Australian preserve set aside for “cute-and-furries”, being more pristine examples, as well as the numerous parks, preservations and conservations that dot the globe, albeit “protecting” the lives within them imperfectly. Despite the likely, if not inevitable, failure of many of these locations’ missions, they are undoubtedly still very beautiful and useful for what they are. Aestheticism goes a long way when the daily commute is steel and concrete, I suppose.
The Rambunctious Garden CH 1 and 2
In the The Rambunctious Garden, Emma Marris tells us of the many assumptions that the public has on our existing wildlife and nature as being a foreign distant place that had been “untouched by grubby hands.” She also tells us about the ideas and plans that conservationist have in order to preserve natural ecosystems, and try to bring them back to their original ecosystem, one untouched by humans. However, she also shows us how many of these ideas are flawed and impractical.
Marris tells us that conservation of ecology has been greatly limited to spaces that are the most green and usually the least populated areas on Earth. Marris wants the public (and most conservationist) to drop these assumptions and see that nature is not restricted and can be found in urban environments as well. “Conservation can happen in parks, on farms, in the strips of land attached to rest stops and fast-food joints, in your backyard, on your roof, even in city traffic circles,”areas you would not assume need to be conserved. She gives us a new perspective on nature, but continues to explain the problems we face today.
Marris portrays conservationist to be almost stuck in the past, “reminiscing” and “romanticizing” nature as something that must be pristine and devoid of human presence. She explains that most conservationist and ecologist formulate a “baseline,” which is basically a “reference state, typically a time in the past or a set of conditions, a zero point before all negative changes.” Some ecologist consider the baseline to be the landscape that was present before Europeans arrived, and some go as far as setting the baseline to before any humans, including indigenous arrived. The baseline says that the present nature is broken and must be restored to its “correct state.”
This seems like valid reasoning on paper, however Marris points out the biggest problem with this: “ecosystems simply cannot stay unchanged for more than a few thousand years.” She explains that the ecology for major parks, like the Yellowstone, cannot remain constant. The baseline set for Yellowstone Park is set to the environment of the nineteenth century, an era known as the Little Ice Age, which was much colder than our climate today. The plants and animals that lived during that century were able to thrive under those conditions. About three hundred years later, the same ecology would not be able to thrive in a warmer climate, and ultimately be replaced by a more adaptive ecosystem.
Rather than just agreeing with Marris, I really admire the points she brings up in her book. Her notion of redefining our classification of nature and approach to boundless conservation areas are ideas that can make nature more enjoyable and readily found (or realized.) I was also surprised by the methods that conservationists have used to bring some ecosystems back to their baseline. Spending years to pull out nonnative species of flora, poison rabbits, and shoot out the many wild animals in an area is unethical. Conservation is needed to preserve the natural world, but it is unnecessary to recreate the same ecosystems of the past.
Rambunctious Garden: Chapters 1-2
Emma Marris begins her book Rambunctious Garden: Saving Nature in a Post-Wild World by informing the reader exactly what her main points throughout the book will be. She suggests that the previous ideas of conservation are flawed and states that the book “is about a new way of seeing nature.”
Marris explains that humans have previously thought of nature as something pristine and far away. This concept comes from the earlier ideas of conservation, which involved setting aside wild spaces as parks that would be left alone by humans. One of the major flaws in this idea is the fact that humans have had such a great impact on the environment that it is impossible for any part of the world to be pristine and untouched by humans.
As Marris describes, scientific studies of the environment use a baseline. She defines a baseline as a reference state and “a zero before all negative changes.” She lists the many flaws with baselines. For one, it is nearly impossible, if not impossible, to properly return an ecosystem to a point before human interference. Marris uses Scotia Sanctuary as an example of a park attempting to restore an ecosystem to a baseline. Clearing the animals that had been introduced to that region of Australia out of the sanctuary was an extremely difficult task that involved “incredible patience and commitment.” While some of the introduced species in the sanctuary, such as goats, were easy to get rid of, others, including cats, were not. One cat took one hundred eighty seven nights to catch. This proves just how much it takes to make an ecosystem pristine. It takes a significant amount of human intervention to create and maintain a sanctuary such as the Scotia Sanctuary. As Marris points out, considering the amount of human intervention required, it is difficult to say that a place like the Scotia Sanctuary could be considered wild.
A second flaw with the use of baselines is that, even if they can be achieved, we would only be returning these areas to their state before humans arrived. This would be wrong because, even without human intervention, nature goes through changes.
Baselines definitely have benefits for conservation. They give us an idea of what we need to do in order to preserve nature and biodiversity. However, it is important to understand that the goal doesn’t need to be for an ecosystem to perfectly match its historical state. To do so would be unrealistic and incorrect.
Another flaw in the previous view of nature is that it seems to ignore the parts of nature that actually are close to us. Marris argues that nature exists in even the most developed areas. She points out that, when we stop only considering the pristine to be nature, we begin to see it all around us. Even in heavily developed areas, nature exists in yards, on streets, along rivers, and in more places than we realize. Even introduced species are a part of nature.
Marris argues that, because humans have such a great impact on the world, we need to “admit our role and even embrace it.” I agree with many of the points she made and I believe we need to look at nature in the bigger picture and, instead of focusing so much on conservation, we should also be putting more effort into researching and implementing ideas to improve what nature we have locally.
nahid bakhtari
According to the articles, anthropocene can be defined as our present geological era marked by the advent of the Industrial Revolution, where humans have had a massive and dominant impact on earth’s various ecosystems. People have argued the negative and positive impact of the anthropogenic imprint, and how we must also understand urban ecology, human interactions with nature in urban communities, to solve the many problems we have. Both articles argue opposing sides to the “conservation of nature” argument; Vitousek arguing that “human alteration of Earth [has been growing so substantially]” in a detrimental way that it may lead to an extinction of our natural world unless extensive conservation is practiced, while Kareiva claim that the human population is growing and needs the natural resources on earth, and there is no slowing down these rates.
Vitousek et al point out in their article as they discuss the impact human dominance has had, and the facts they give are compelling enough to want to begin your own conservation movement. Almost 39 to 50% of the land has been transformed or degraded, a large percentage compared to the few hundred years it took to change it. Since I have a penchant for marine life, the fact that “commercial marine fisheries around the world discard 27 million tons of non-target animals annually” is upsetting, and a cause I would fight for. I also love to eat fish, but “as of 1995, 22% of recognized marine fisheries were overexploited or already depleted, and 44% more were at their limit of exploitation” makes me want to avoid fish even more than the mercury factor. Extinction of animals has also been severe with almost 20% of mammals going extinct and 11% of birds.
Though Vitousek makes good points, I do not completely agree with him. His article had been written about fifteen years ago during a time when people were stringent about our need to conserve natural ecosystems, and also enough time to change the mindset of most conservationists. That is why I like and agree more with the recent article Kareiva et al article that claims that we have made significant changes in the past decade conserving the earth, and human starvation is a bigger problem. And their idea that it is best to use the Earths land and resources to help the starving in developing worlds is better than leaving them untouched for the few who can access preserved (gated) areas.
Scientists have seen the effects of the damage we have done in the past centuries, and action has been taken. We now have solar, wind, water, and other cleaner sources of energy. The only problem is for making these sources of energy more economical. And another point that Kareiva et al brings up is the fact that the Earth knows how to heal itself. The damage we have done has been cleaned up like the oil spill in the Gulf of Mexico (which I was surprised would happen). Rather than preserving natural landscapes to be untouched, I think it is better to use the resources to help mankind.
Rambunctious Gardens-Chapter 1, 2
Compared to many other ecological readings, such as the previous Vitousek and Kareiva articles, Rambunctious Gardens is a more reader friendly version. Within the first two pages, Emma Maris clearly states her thesis of the book by saying “this book is about a new way of seeing nature” (Marris, 2.) She combines the theme of the articles by Vitousek and Kareiva in the first two chapters, by arguing that “we are already running the whole earth,” (2) and that baseline conservation techniques are harmful because regardless of human influence the earth is forever changing.
The first chapter, Weeding the Jungle, focuses on the concept of how modern nature should be defined. Marris does this through the term Rambunctious Gardens, which she defines as nature that is “tended by us”, and describes that as any strip of land surrounding us that contains greenery, even “in your backyard [and] on your roof” (2.) She then gives a description of the modern conservation techniques of maintaining a pristine wilderness, which contrast her idea of a Rambunctious Garden. One thing that Marris does, which makes her book more approachable to the non-informed reader, is give a brief background history of the ecological terms she uses. For instance, the term baseline is clearly defined, given examples of, and her opinion of it is plainly stated. The two points that Marris makes about baseline conservation techniques is that there is no such thing as “pristine wilderness” anymore because humans have touched all parts of the earth, and that baseline conservation techniques are damaging to the present ecosystem because “conservationists must shoot, poison, trap, fence, and watch, forever watch” the “invasive species” that enter these ecosystems. Marris backs up this argument by giving several examples of areas that she visited, including the Scotia Sanctuary in Australia. She indirectly conveys this message by giving examples of how maintaining a baseline defies the idea that the pristine wild is “unmanaged” (12.) Marris offers a new outlook on conservation by saying we should be “layering goals and managing landscapes with an eye to the future “ (15.)
Marris continues on in the second chapter, The Yellowstone Model, with ideas from the first chapter. In the first chapter she argues against the assumption that a baseline is “good” and extends this argument by challenging the assumptions that there is a “balance of nature” and that areas devoid of humans is necessary for pristine wilderness. This chapter in general contains more history because she explains the “Yellowstone Model,” and how conservationists over the years have come up with concept of “setting aside pristine wilderness areas and banning all human use therein” (18.) She accounts this model to the famous park advocate, John Muir who was a forefather in the idea of “pristine wilderness.” The consequence of having a human free park, was the displacement of the native tribes that lived on the land, and according to Marris these were the people doing the “least harm” (26.) Furthermore, Marris discusses this concept of having a “static or stable nature” (27.) She goes back and gives a brief history of the concept of the balance of nature derived by Clement, for those of us part of the less informed scientific community. She disproves his point by the experiments of Scientist Botkin, who proves that the “balance of nature,” which Clements believed to be true, was false because through his studies he found that “chaos, rather than equilibrium, is more common” (30.) Marris continues on by going against this concept of global warming, and says that regardless of human intervention climate will increase because “we’re in an interglacial now,” meaning that the earth is getting out of the ice age (32.) Essentially her point for the second half of he chapter is that there is no correct baseline to look back to because the earth is constantly changing, and these conservation efforts that look at the baseline are all going to waste. Overall, Marris summed up her thoughts and ideas cohesively for the common individual to understand.
From AUS to USA, The Hunt for Pristine Wilderness Continues
Rambunctious Garden, written by Emma Marris, opens up with tales of conservation methods in Australia. In Chapter 2, Marris goes on to describe the Yellowstone Model. Marris is quick to assert her point that using baselines for conservation may not be the best, or even damaging, to the ecosystem. The author defines a baseline as a point in time at which conservationists aim to restore the land to “pristine wilderness.” It is most often pre-European. Instead, she says that ecosystems are constantly changing, and human efforts to preserve these lands should reflect that, instead of restoring them to an anachronistic time.
In Australia, conservationists have attempted to restore lands to pre-European times. The Australian Wildlife Conservancy, in 2009, tried to restore a 250 square mile piece of land, Scotia Sanctuary, to pre-European times. This project was arduous and expensive. The Australian plan faired well because it required killing feral animals like goats, foxes, cats, and rabbits. The hunters shot the goats, trapped the foxes and cats, and poisoned carrots to rid the rabbits. That is quite an extreme example (that PETA would dislike), but it worked in the sense that the “little furries” were now under no threat. Native species thrived. Therefore, Scotia Sanctuary proved that achieving a historical baseline was possible, under intense management. But what does “management” entail? Is this land no longer wild if it is “managed?” Maybe. Is this land no longer “pristine wilderness” because of human intervention? Not quite. Let’s look at America’s answer to the quest for pristine wilderness.
The Yellowstone Model serves as a guide to the world of what conservation is today: setting aside wilderness areas and banning human use apart from tourism. Never before had a society voluntarily restrained itself using natural resources in deference to higher uses of nature such as pure enjoyment (Marris). Now 13% of the Earth’s lands are protected areas. Is this necessarily right though? In 1877, Native Americans were forcibly removed from their lands. This is very ironic because it was the care of the Native Americans that first interested the conservationists in the land. Needless to say, the ecosystem suffered without its caretakers. I think Marris will use Yellowstone of what the face of conservation used to be. Sure, having this great area of “untouched” space is great but is it really productive? Does it really suit to the needs of the land and the people? She compares it a bit to the European model of aiding human use and avoiding extinction. Americans perfected this model of nothingness, leaving the land as it is, and exported that to the world. Both ideas are being debated here.
Emma Marris presents excellent cases so far. Australia’s model of returning to the baseline proved successful. Wyoming’s Yellowstone has also seen success. Both attempt to move their respected lands into “prestine wilderness,” Yellowstone with no activity whatsoever, and Scotia Sanctuary with human intervention. I am inclined to think that Marris believes in the latter.
A Vision of a Rambunctious Wilderness
In Rambunctious Garden: Saving Nature in a Post-Wild World, Emma Marris introduces the idea that today’s understanding of conserving nature is flawed and backwards. Importantly, Marris asserts that nature it is not pristine and simple, and it is not constant and static. It is constantly changing—whether it occurs naturally or artificially. Instead of having a “pristine wilderness” concept, Marris suggests a vision of a “rambunctious wilderness” should be taken on to coincide with human activities and actions, not against it.
In the first chapter, Marris criticizes human efforts of attempting to restore nature to a state in its past. Trying to repair an ecosystem’s damage from invasive species, destroyed plant life, and altered climate or territorial natural states, cannot magically bring back nature from the past. Although this type of restoration sounds extremely optimistic, it is not realistic. For example, since more than fifty percent of Hawaii’s plants are nonnative, an experiment of ridding a specific forest of all nonnative species took place to see if native species would be reintroduced naturally. It was discovered that only a few native seedlings reappeared on the forest floor and there were no drastic, laudable changes. These efforts also have complications in documenting about the point of restoration, as well as the requirement of much time and money. In the second chapter, Marris continues with “The Yellowstone Model” to reason the impossibility of perfect restoration. Since nature is constantly changing, a “stable equilibrium” that societies want to conserve simply does not exist.
Marris also makes a significant point about the misconception of keeping nature separate from humankind. The human species has had an impact or influence in every ecosystem on the Earth, already! Nature includes “the bees whizzing down Fifth Avenue”—it is around us and within our reach. It does not make sense to conserve nature by removing, sometimes forcibly, humans living on the land that ‘must be conserved’. On the contrary, Marris actually suggests, “achieving coexistence between humans and other species” to avoid the removal of indigenous peoples and to allow the environment to thrive more. Instead of seeing nature as something untouchable in the distance, people should start seeing the beauty of nature that can coexist with humanity.
Marris succeeds in educating her readers of the importance of embracing nature as it is, while asserting the false perceptions of “restoration” and “conservation” that most of society has today. Throughout, her general use of examples expresses a dedication to research and for finding alternative, and maybe even more effective, solutions to society’s current problem with nature—which allows readers to take her seriously and even with a new perspective.
Rambunctious Garden
Emma Marris, in her book Rambunctious Garden: Saving Nature in a Post-Wild World, examines the pervasive yet incorrect way people see nature and offers a more proper way to approach the environment around us. Two strong points she makes in the first two chapters of the book are the following. One, the earth’s ecosystem is never pristine and despite any human efforts, it will never be. Second, ecosystem is never stable and constant. It is always changing, both by human disturbances and internally, on its own.
Both claims above are new and bold. They are not what most of us are used to hearing. Marris also claims that for many many years, people including ecologists who’ve dedicated their lives to study the earth’s ecosystem and conserve nature have believed the opposite (3). One, the correct and the best way to conserve nature is to preserve its “pristine wilderness”. Or to recreate the area to resemble the way it used to be before human dominance over it. Second, “the idea of nature as unchanging or fluctuating (27).” Much of the ecologists failure to conserve nature arises from such incorrect views of nature. Marris’s goal in her book then, is to shatter such long-held and culturally engraved ideas about wilderness. It is to show us a “new way of seeing nature” (2). It’s about better understanding how nature operates so that we can better conserve it. Rambunctious garden isn’t about “just building walls around the nature we have left” but about creating “more and more nature as it goes” (2-3). Its focus is not on the past but on the future. Not how nature used to be but what it should look like as the world continues to evolve. Marris attempts to make the point that nature is everywhere, not just in protected parks or isolated landscapes, and most importantly, the beauty of nature can co-exist with humanity (3).
Human interaction with nature is constant but our relationship with it is limited to our “romantic notion” of what it should be like: untouched. Marris demonstrates this misfortune very well with the Yellowstone National Park model. The park’s conservationists did not understand “that the ecology of Yellowstone is not stable over historical or prehistorical time” (34). Their goal then, was to return it to its pristine state or baseline. Naturally, they thought, to do that, the park should exist apart from humanity. Consequently, people living in the area were kicked out (26). In this example, conservationist’s blinded view of nature resulted in futile and ineffective action to conserve it. Now we better understand that “a protected area doesn’t have to be depopulated to work”(26). Regardless of people, nature change on its own. With such new knowledge, “obsessing over 1872 is” definitely “no longer as helpful to park managers (34). The focus now then for the park is on managing resilience, which is “an ecosystem’s ability to endure disturbances…without substantially changing in character” (36).
I believe she has made a very good point. Humans have dominated and continue to affect every area on the Earth. We have altered its climate, land, plants, as well as the animals living in it. And so making humanity the enemy of nature would be foolish. We need to work together, not backwards in time but to the future, equipped with a new way of seeing nature.
Rambunctious Garden Chap 1,2
The main idea of the author seems to be that although conservation is not necessarily futile depending on its goals, if its goal is to keep a place the same as it was years ago that is vain and so is our view on nature. The author lists two ways in which nature has been lost. One is through man. An example would be deforestation. Another is what she calls “misplaced” nature.
Our perception of nature is far away, not in the cities, with no people and untouched by mankind. The author points out that nature is everywhere, even in cities such as birds in backyard. Even if not pristine as we view nature, it can still be viewed as such. After all, there is no going back to when nature is considered pristine. The author points out changes happen to nature all the time.
She understands that changing our ideas is hard. The methodology she described as how conservationists go about preserving an area. There are baselines that are the goals, the ecosystem that conservationists want to obtain. According to our nature ethics, it is to go before human touch. Problems that arise though are ecosystems are complicated to figure out. Ecosystems are always changing with or without humans. Although a baseline is created, we don’t always know how the ecosystem looked back then. Most important of all, these goals are almost impossible to achieve unless decides to put in large amounts of money into it and everywhere makes it their priority. I agree with the author when she says it is almost impossible to obtain this.
Even though parks and reserves can be worth having like Yellowstone Park and the reserves in Scotia and Australia, nature is always changing. There are new ways to embrace nature. When the grad student saw the ecosystem in Hawaii, he wasn’t like the other ecologists who believe that it is something to scoff at. They can still have benefits and the ways they interact with each other are unique and interesting as those before. As she says these ecosystems are the ones driving the earth, not the ones of the past.
Even though human touch is thought to be bad, parks with fertile land had people there. The reason nature was there however was the people living there were doing the least harm.
I believe she makes a good case of her main point. People want a stable equilibrium in the ecosystems but it almost impossible. Ecologists know that change is the norm of ecosystems. Some changes in forests aren’t even the work of human. Sometimes it is the work of nature such as the Ice Age. Ecosystems aren’t static.
Even if an ecologist knows nature is always changing, he will try to establish a balance of nature policy. They always change. Even park managers admit so and hope that the system will be resilient. Even knowing change is happening, manmade change is still held to be bad. Searching for the untouched is vain in searching the unchanging. I am one of those people, too. Even if I know nature always changes, having our influence on nature makes me feel conflicted as to what should be done. Even if nature always changes, we can’t help but feel responsible for those changes. I see her point but saying preservation is vain feels off to me.
Rambunctious Garden, Chapters 1&2
Emma Marris, in the first two chapters of Rambunctious Garden: Saving Nature in a Post-Wild World, expresses her opposing view to the common traditions of conservationism that aim to maintain a “pristine wilderness” (2). The first chapter, “Weeding the Jungle,” mainly criticizes the practice of restoring nature to a state of its past. For years conservationists have rid ecosystems of invasive species, reintroduced native species, constructed elements that were once present, and created habitats in an attempt to bring back original qualities from the designated point in time. Although the outcome sounds tempting, such an achievement is practically impossible for several reasons. Firstly, the example of Hawaii that Marris described did not produce particularly spectacular results. Secondly, there is usually very little documentation about the point of restoration so there is no way to know how successful the project was anyway. Thirdly, executing these restorations consumes a great amount of time and money that the world simply does not have to contribute to the cause.
The reasoning behind the impossibility is further explained in the second chapter, “The Yellowstone Model,” which is mostly about how nature is forever changing. According to paleoecologist Feng Shung Hu, the stable equilibrium to which conservationists desire to return Earth’s ecosystems simply does not exist (Marris). The second chapter also discusses conservationists’ view of human interaction with nature. A significant point Marris repeatedly points out is that humankind has interfered with every piece of nature that exists on the planet. Even so, for a long time conservationists have seemed to believe that the best way to approach nature is to separate it from people altogether. It has been determined that in doing so, the United States would be “a white continent flecked with green here and there” (37). Furthermore, native people have been forced out of their homes so that the parks could be created and kept untouched. As for this practice, Marris argues for the exact opposite: “achieving coexistence between humans and other species” (32), which would allow for more nature to thrive and prevent the removal of indigenous peoples. In other words, she advocates for a ‘rambunctious garden’ – nature that is created and maintained by humankind.
Overall, Marris has developed a powerful argument. The conservation traditions that she rivals are widely known and accepted. However, she manages to bring to the table a different perspective – the ‘rambunctious garden’ – on conservation that has been previously addressed by few but never fully recognized. Challenging such broadly established practices is a difficult task, but she does it extremely well. Throughout the two chapters, Marris provides clear and strong support for her arguments. Offering plenty of examples, she proves that she is not just complaining about the failure of various conservation tactics and creating surreal solutions, but that she has researched those failures and thoughtfully crafted alternative solutions. If the rest of the book continues with a similar format of eye-opening opinions and substantial evidence backing change, by the end of it Marris’s arguments will have definitely influenced my outlook on conservation.
Rambunctious Garden Chapter 1&2
In the first two chapter of the book Rambunctious Garden, Saving Nature in a Post-Wild World, Emma Marris addresses issues about nature. According to Marris, we have lost nature in the sense of how it has been destroyed, and also how we have misplaced it. Marris makes a clear argument in the beginning of the first chapter about the common misconception of how people view nature. I agree with her that when people think about nature, things that come to most of their minds are forest, wild animals, and plants. Natures shouldn’t be something that is “out there”, somewhere far away from human touch; instead it can be in everywhere around us. In Marris’ words, “Nature is also the birds in your backyard; the bees whizzing down Fifth Avenue in Manhattan; the pines in rows in forest plantations the blackberries and butterfly bushes that grow alongside the urban river…”(Marris, 6) She suggests that nature is not only about those national parks such as Yellowstone, it can be anything that’s around us.
Marris also makes a strong argument that “Nature is almost everywhere. But wherever it is, there is one thing that nature is not: pristine”(Marris, 6). We are living in a planet that is constantly changing; for example, carbon level keep increasing, many species were moving from one place to another, and there is also a huge climate change. All these changes were closely related to human’s actions, in which high carbon level and climate changes are results of burning fossil fuels. Because of the significant impact that human can have on the nature, people must be responsible of their actions, and start looking at nature in a different prospective. Marris makes a forceful statement saying “we can find beauty in nature, even if signs of humanity are present.” I truly agree with this quote, because of our undeniable influences on nature, human is actually a part of the nature, which cannot be separated. Keeping nature away from human is not the most efficient way of reserving nature. Many conservationists are trying to restore nature into a state before any presences of human. However, it is very difficult for conservationists to achieve this goal, and sometimes they even have problem decide what their baselines are, because nature is constantly changing, and we don’t always know what these places were like thousands of years ago. We cannot restore everything to its original fate; therefore, we ended up having “little islands like the past” (Marris 16)
Marris also gives an example of Yellowstone to argue that nature shouldn’t be keep away from people. Millions of indigenous people have been moved just to protect nature, but Marris believes that this is not the effective way of saving our nature because natures and human are closely tied with each other. According Marris, these indigenous people can be the one who is doing least hurt to the nature that they live with. I think Marris did a good job in the opening of the book; she has made several strong arguments about nature with the support of examples.
Rambunctious Garden Ch. 1 + 2
From the first two chapters of Emma Marris’ Rambunctious Garden, it is apparent that the main point she wants to convey is that the goals of conventional ecologists are flawed and outdated ways of approaching conservation. She is explaining her thoughts on how science’s and the public’s romantic stance on nature being simple, pristine, and unaltered, should not be the basis for modern day conservation. The ideal vision of a pristine wilderness should be put behind us to allow for a more rambunctious wilderness to grow in conjunction with human intervention(hence the term garden).
Chapter one establishes the idea of a baseline that many ecologists and conservationists strive for when protecting a land. Marris deconstructs the idea of a baseline throughout the two chapters to allow the readers to see that the world and nature is not stagnant or unchanging. The baseline that most ecologists strive for is one that is unaltered by people, or has most of its native species intact. Marris makes it clear that a pristine wilderness is simply unrealistic, which is a point that I can agree on. She says that, “the ecosystems that look the most pristine are perhaps the least likely to be truly wild.” If a baseline were to be achieved, constant human intervention, like at the Australian Scotia Sanctuary, would be necessary to keep the lands in a “pristine” state. Aside from the costs of maintaining pristine wilderness, the fact that humans are needed to tend to these protected lands weakens the pristine aspect of mother nature.
These “romantic” ecologists tend to believe that an unchanging nature is how nature was aways supposed to be. They believe that a “balance of nature” or equilibrium in an ecosystem is the ending point for any stable ecosystem. However, most ecosystems never hold still. There is no point where nature is always in in equilibrium, so the romantic nature that we try to recreate is an unreasonable idea. Marris brings to our attention that change is unavoidable, thus we should take advantage of nature’s characteristic to be wild and rambunctious. Marris mentions that, currently, many conservation park managers are looking towards the idea of “resilience” in their ecosystems. This is the idea that ecosystems are strong enough to gradually change on their own, and are not unstable to the point that several species are threatened. If an ecosystem does reach a point of instability, human intervention is welcomed.
I find that Marris’ case to be compelling, but I also feel that she does not give enough credit to the current conservation/protection of ecosystems. While the idea of allowing a rambunctious garden/world to grow is charming, protecting special lands and endangered species are still issues that have to be addressed. There should be a balance between protecting lands, maintaining unstable ecosystems (ecosystems where some species are threatened), and allowing for nature to take its course.
Rambunctious Garden – Chapter 1 & 2
In her book Rambunctious Garden: Saving Nature in a Post-Wild World, Emma Marris presents a new way of viewing nature. In her eyes nature is not limited to untouched ecosystems, but instead, it is everywhere. Marris rejects the conservationist approach of fencing off nature in hopes of preserving or attaining the pristine. Instead, she supports the idea that nature is in constant flux and consequently, proposes the cultivation of wild gardens alongside human development.
According to Marris, the typical conservationist fruitlessly aims for a retreat to the baseline, before human actions induced negative changes on the ecosystem. Using Hawaii as an example, she proved that restoring an ecosystem to its prehuman baseline is almost impossible. Human activity on the planet has altered temperature, landscape, and even the air composition. Hence, when experimenting on the possibility to reverting Hawaii’s Big Island to its native tree species, Marris found that the results were discouraging. In addition, she noted that the cost burden of getting rid of invasive species, repopulating the ecosystem with its native trees, and maintaining the baseline conditions would be too expensive for any government to bear. As a result, Marris does a good job of affirming her point that returning to the baseline is not a feasible approach to conservation.
Likewise, Marris also makes a good case for approaching nature by looking to the future, where gardens sprout amidst the destructive human hand. She states that there is no scientific reason for believing that the baseline nature is better than the nature of today. In fact, she supports the idea that ecosystems have always been subject to change. Meaning, there is no scientific evidence supporting the idea that nature will be stable or static if reverted to its pristine state. As a result, Marris claims that we are better off focusing on the future ecosystems that will be most responsible for driving the Earth’s natural processes. Hence, the search for the pristine should be replaced with a desire to cultivate the “gardens” in our own backyard. In other words, Marris believes that we need to foster a new thought, where nature is embraced as being everywhere. Through this idea, we can begin the process of creating rambunctious gardens that encourage humans and nature to interact, grow, and coexist.
Overall, Marris made a good case for leaving behind the ideals of a pristine ecosystem to focus on a future where nature is conceived as being almost omnipresent. Her ideas have a clear logical progression that supports the incorporation of both the human hand and wild nature.
Revisiting History and Discussing a Better Future for Nature in “Rambunctious Garden”
Emma Marris in the first two chapters of her book Rambunctious Garden: Saving Nature in a Post-Wild World makes her main points clear: that “there is one thing that nature is not: pristine,” humans “are already running the whole Earth,” and it’s too difficult and time-consuming for society to turn back the clock and attempt to conserve parts of the world as if they were untouched by humans (2). She goes through several examples around the world as evidence that the past and present efforts of conservation are invalid, discussing such ideas as the “baseline” in-depth and evaluating conservationism in America from Thoreau to today’s ecologists following in his steps accordingly. The idea that nature is peaceful, undisturbed, and stable is false, according to Marris, and there must be changes in the way society visualizes nature and the ways in which we approach the topic, from an ecological and topical standpoint.
One of the examples that she uses to demonstrate her points takes place in Hawaii, where presently “half of the plants in Hawaii are nonnative,” and study plots used by other scientists to restore tiny parts of forests back to its supposed pristine state appear “a bit sad and empty, like someone’s living room in the middle of a move-out” (6-7). Apparently, efforts to restore plots like these have failed, as “the mature native trees had grown very little,” and the trees were being restored by humans, ironically: after all, why should humans interfere with a typical ecosystem, that changes frequently and has very little stability? Marris elaborates more on this idea in the second chapter, when she says that “(g)enerations of field ecologists tried to make their observations fit this model, but the real world was stubbornly unpredictable” (29). Although the instabilities of ecosystems have been confirmed decades ago, the “assumption of stability is still with us and is as tenacious as ever” (30).
Marris talks extensively about the history of conservationism, rooted in Europe and America where writers such as Wordsworth and Thoreau criticized their urban neighbors and surroundings, wanting to escape them and explore the solitude and balance that is only found in places away from rustling towns and people. Yet, using Thoreau as an example, some of these writers detested the wilderness, contrary to what most people would believe: he “actually preferred a middle ground between the truly wild and the truly civilized” (20). Another famous conservations John Muir furthered the “wilderness cult” by “trying to bring civilized humans to God through the glory of His mountains and forests,” believing that the wilderness “must not be changed radically to suit man” (21). It was and is “nature for nature’s sake,” a purely human invention that harms the way in which humans can co-exist with their environment.
Hopefully more changes have been taken on by governments, ecological organizations, and other entities to shift our conservation efforts towards the future by accounting for human dominance; yet, a change in Western culture and attitude towards nature will take quite a while, as the world continues to urbanize and people run out of space for their so-called “solitude.”
Chapters 1-2 Rambunctious Garden
Through the first two chapters of Rambunctious Garden, by Emma Marris, the main point being stressed is that the reader and society as a whole must rethink the way we conserve nature. She describes rambunctious gardening as “Proactive and optimistic; it creates more and more nature as it goes, rather than just building walls around the nature we have left.” People are often worried about protecting the nature we have left, but they fail to realize that a greater impact can be made if we let nature take its coarse and not build fences around it.
More than half of Hawaii’s plants are nonnative. An experiment took place to determine whether a native Hawaiian forest would bounce back if all the introduced species were removed. The results that Marris discovered were that quite a few native seedlings appeared on the forest floor. Marris realized that despite not being able to turn back the clock, many conservation projects like to recreate a former time of the native land on a larger scale. Examples of this would be know as little islands like the past.
The past ten years, according to Marris, scientists have moved beyond focusing on the past, but now focus on the future and asking themselves what they would like it to look like. “No single goal will provide for a sensible, well-rounded conservation program…Layering goals and managing landscapes with an eye to the future, rather than the past, is the cutting edge of conservation.”
Marris goes on to talk about the Yellow Stone National Park effort to preserve the area. About 13% of Earths land is protected area. Initially, most early parks preserved land that could bring tourists, but later after the 1940s, land such as the less sexy swamps that were rare in ecosystem were finally being preserved. To sum up the first two chapters by Marris, she tells us that part of the beauty of ecology is its change.
I agree with many of the strong points that Marris made against the current ways of conservation. Her idea that people are making nature conservation just for the sake of preserving nature alone is a strong one. She supports it by saying that we as humans should accept that we have modified nature and should preserve it the way it is, not by trying to reinvent the past. Nature has its ways of balancing things out and as humans we should help it through the process instead of providing it with barriers. The key to all of this is to embrace nature, and since ecosystems never hold still, we should value the history that is taking place right in front of our eyes.
Rambunctious Garden – Chapters 1 + 2
The main point Emma Marris, author of Rambunctious Garden: Saving Nature in a Post-Wild World, is trying to get across in her book is represented in one of the lines from the opening chapter: “This book is about new ways of seeing nature.” Marris tries to point out the flawed way many ecologists and conservationalists see nature and try to preserve it, and how due to the changing definition of nature, there must be new ways to study and take care of it. Marris has made a very good case in the first two chapters of her book, explaining the dynamics or nature and bringing many examples of her experiences studying the ecology of many places, including Hawaii, Australia, and Yellowstone Park.
Marris argues that nature must be viewed and understood correctly in order run it correctly. Her main argument is that people must admit that we are running the world in order to run it “consciously and effectively.” Marris provides many examples of how people are running nature because of the ways nature is lost to us and how people have brought about so many changes in nature. She explains that nature is lost in two ways, it is destroyed and we “have hidden nature from ourselves.” People often believe nature is “out there” somewhere but not accessible or near to us. Marris makes a good case talking about the everyday aspects of nature and how it is “almost everywhere.” She mentions nature is in the commonly thought of places such as in the forests but it is also found as well in the cities, where plants still grow and bees still pollinate. Focus on preserving nature is placed onto natural parks but because nature can be found everywhere, Marris argues there should also be a larger focus on the everyday nature found around people, whether it be in a large city or rural area.
Conservationalists are “desperately trying to stop the wilderness from changing” yet as Marris points out, “there is no pristine wilderness on planet earth.” People have been changing the landscape for many years on a global scale with things such as “climate change, species movements, and large-scale transformations of land.” Marris provides many examples of the way nature is adapting such as how “bobcat families [are] moving into foreclosed suburban homes.” Because nature is constantly changing, “whether humans are involved or not,” there are many problems with the common practice by ecologists of setting a baseline when studying an area. A baseline is used to compare the current ecological state of an area to a certain period of time, but many factors affect the validity of such measurements.
Marris’ main point of the book seems to resonate in one of her quotes, “we can find beauty in nature, even if signs of humanity are present.” Marris disagrees with the the static way ecologists are trying to preserve what they consider as the only nature worth preserving, and argues that nature is all around us and effected by us, so it should be studied with that in mind.
Rambunctious Garden Ch 1 and 2
In Rambunctious Garden, Emma Marris tries to point our mistakes about looking towards nature from an idealistic point of view- that it exists untouched and pristine in a distant corner. Author Marris also points out that the traditionally held point of views about conservation must also be modified because nature not only exists in national parks, boreal forests and the Arctic, but also in backyards, forrest plantations and even city blocks.According to Marris, we must abandon our romanticized notion of pristine wilderness and take on the responsibility of tending a new garden of nature, which is everywhere. We must move on from the deeply held views of “pristine wilderness” as the ideal for every landscape, and adopt a new standard which is as dynamic as the changing ecosystems themselves.
Despite human presence, ecosystems are always changing due to several factors, therefore Marris in the first chapter points out the difficulty in setting an appropriate baseline for establishing a time period- where nature is pristine and untouched. Furthermore, in terms of time and money the procedure often proves to be rather difficult and impractical.
It is clear that most ecosystems or wildernesses have been misplaced, but still several conversationalists strongly adhere to the idea of creating restoration parks that aim to recreate a former time- for instance Cathcart’s efforts in Australia, where non-native species are being eradicated and “pristine wilderness” is being kept in fences.
According to Marris, there is a distinction between preventing extinction and trying to recreate a former system. It may not be feasible to return to the past, but preventing extinction certainly possible and does not require perpetual weeding.
A new view of conservation needs to be established, and the future must be embraced rather than abandoned in an effort to bring back the past. Just because an ecosystem has changed, it doesn’t make it worthless. They still drive the natural processes and help with problems such as climate change.
No one approach to the conservation efforts is adequate, what is important- to layer goals and manage landscapes with an eye for the future, rather than the past. The whole notion of preserving what is native and pristine is a misconception which is deeply rooted into the fields of ecology and must be modified.
I strongly agree with Marris’ point of views- Just because a specie is non-native, and fits perfectly well into an ecosystem does not make it any different. It helps achieve the overall goals and contributes to the landscape. Furthermore, in the current world wilderness in its pristine and romanticized form can only be kept in controlled zoo-like environments, so is it truly wilderness if its kept tamed? And is justified to eradicate a specie because it doesn’t originally belong to that landscape? Marris makes excellent points and questions are deeply rooted views about conservation, wilderness and ecology.
Rambunctious Garden – Chapters 1 and 2
Rambunctious Garden by Emma Marris seems to be a very thought-provoking book. Throughout the first two chapters, Marris explains her views on the current state of ecology. First, Marris makes it clear that in today’s day and age there is no such thing as “pristine wilderness.” She explains that no ecological habitats have been uninfluenced by humans since prehistoric times. Next, Marris attacks the attempts of many conservationists to return specific habitats to the way they were before humans arrived. Marris attacks the Yellowstone Model and elaborates on the difficulty and costliness of achieving this goal. Finally, Marris argues against the “balance of nature view,” which states that nature does not change on its own very much, but instead remains at a stable equilibrium. Marris retorts that chaos is more common than stability in most ecosystems and that natural events such as fires and climatic changes are constantly changing habitats all over the world.
It seems clear from these two chapters that Marris’s main point is that there is beauty in the new ecosystems that are being created today. Although some conservationists may argue that ecosystems in places such as New York City are impure, Marris believes that native ecosystems are not any better than these new “synthetic” ecosystems. Marris finds beauty in this new nature in which nonnative species interact with native ones. In fact, she believes that these new “synthetic” ecosystems are just as beautiful as natural ecosystems untouched by humans. Marris argues that “the changes, the disturbance, the outlying events, and the confounding factors are often the most important drivers of the system” (34). This quote exemplifies her belief that conservationists must stray away from trying to return ecosystems to the way they were before humans arrived. Marris is a realist and understands that in the highly advanced societies of today it is impossible to eliminate the effects of humans on natural ecosystems. She recognizes that it is inevitable that humans will affect nature. This is demonstrated when she states that “we must temper our romantic notion of untrammeled wilderness and find room next to it for the more nuanced notion of a global, half-wild rambunctious garden, tended by us” (2). Just like Kareiva et al in “Conservation in the Anthropocene,” Marris believes that coexistence should be achieved between humans and wilderness.
Marris has made a good case for her point throughout these two chapters. First, she points out the costliness and difficulty of maintaining preserved areas. For example, she writes that it took nearly six years to kill the nonnative species in The Australian Wildlife Conservancy. Also, she illuminates the fact that millions of people have been forced to resettle due to preservation. Finally, she argues that maintaining preservations is nearly impossible due to the extreme amount of money and manpower required.
I agree with Marris’s view on the current state of ecology. I think we need to establish some sort of coexistence between humans and wilderness. This is because the effects that humans have on every ecosystem are impossible to deny. As industrialization continues to increase, ecosystems will continue to be affected. However, humans cannot halt advancement for the benefit of nature. A balance needs to be established between nature and wilderness. We must accept these new “synthetic” ecosystems that are created by humans. If we do not, we will be focused on preserving the past instead of gearing toward the future.
Rambunctious Garden Chapters 1 & 2
Throghout the first two chapters of her book, “Rambunctious Garden: Saving Nature in a Post-Wild World, Emma Marris attempts to reveal her thesis and the main point which will be stressed throughout the book’s duration. She argues that the modern view of most conservationists is mistaken and needs to be adjusted. She claims that this view refers to the “Yellowstone Model,” which was made famous by John Muir and President Theodore Roosevelt. According to this model, natural parks should be set aside as protected areas in order to be restored to their natural conditions, before they were altered and interfered with by humans. Marris argues that this process does not seem plausible for a number of reasons. Firstly, in order to do so, conservationists would have to be able to recreate what this ecosystem may have been like before human interference. Then they would have to be able to reintroduce the species that would have been natural to that ecosystem, while removing all of the introduced species. This process would have required a lot of effort, time, resources and money and would have proved to be worthless.
As an alternative, she believes that instead of using up all of this time and energy in converting nature to a pre-human “pristine” environment, conservationists should work on intertwining the two and allowing them to work side by side and in harmony. She believes that nature in all around us and in this respect conservation can happen wherever we look. She states, “Conservation can happen in parks, on farms, in the strips of land attached to rest stops and fast-food joints, in your backyard, on your roof, even in city traffic circles. Rambunctious gardening is proactive and optimistic; it creates more and more nature as it goes, rather than just building walls around the nature we have left.” Instead of cutting off a section of land and characterizing it as sacred we should support an organization where man and nature can work and live together in order to support the ecosystem and allow it to thrive.
One strong point that Marris stresses throughout the first two chapters is that over the years we have developed a notion that nature is something that is far away and mysterious. In fact, we view nature as a place in which there is an absence of human life and interaction. In reality, there is no such place that can be referred to as truly “pristine.” Not only have humans altered and interfered with almost every ecosystem, but even if this wasn’t the case nature constantly reshapes itself, whether there is human interaction present or not. Therefore, it is pointless to try to reshape nature to its former natural conditions due to the fact that change is constant and ecosystems are always changing, with or without human interference. Therefore, Marris claims that instead of forcing nature and man to become enemies we should strive to combine the two and create a “rambunctious garden” where both can live in harmony with one another.
September 4th – Marris chapt. 1 & 2
Firstly, I have to say that I think the reason that Emma Marris wrote the book Rambunctious Garden: Saving nature in a post-wild world is to explain whether wilderness is pristine or not. Throughout the first chapter she saying that there is a problem with calling nature pristine, she goes so far as to say that, “This dream of pristine wilderness haunts us.” She says this because there is no place in nature that has does not have an effect on mankind. She even provides a date and says that specifically since 2011 there has been no pristine nature on planet Earth. She goes on to say, similar to our readings from last week that conservationism is the wrong way to deal with nature. Instead humans should try and work with nature instead of trying to seclude it. The way Marris describes it is probably the best way to say it, she says, “We are already running the whole Earth, whether we admit it or not. To run it consciously and effectively, we must admit our role and even embrace it.” In other words Marris is basically saying we basically control the Earth, we have been altering the environment around us for as long as we have been around. Now Marris is simply saying that we should take some responsibility to help Mother Nature out and embrace our roles as leaders of the Earth since we affect it the most. One example she gave was how because of humans the amount of Carbon Dioxide molecules in the air is thirty six percent more than it was in the seventeen hundreds. One point that Marris made which I thought was very interesting was the whole idea of baselines, meaning if we were going to try and revert nature back to how it used to be (as in a truly pristine environment) how would we go about doing that? What would be the “baseline”? Would it be from when before humans came to the environment or an earlier time because even without humans present the environment was still changing? I have to say when it comes down to it I thought she explained her points very well, in my opinion she was trying to explain what nature is and why it can not be considered pristine. She clearly explained what pristine means regarding nature and that it can no longer be found because human effects are everywhere in the environment. Truthfully one thing I have to say about the first two chapters is that I appreciated how she brought so much evidence to support her claim and even though at times it became a bit strenuous to read for this particular reason. I have to say that I think the fact that she put so many examples helped me understand the chapters better because if one of her examples did not cut it for me the rest would help me get a good idea of what it is she was trying to say.
Rambunctious Garden, Emma Marris, Chap 1-2
At the beginning of her book “Rambunctious Garden: Saving Nature in a Post-Wild World,” Emma Marris argues that the idea about “true” nature that most conservationists have is an inaccurate one. She claims that the notion of creating protected areas that resemble a time when man had not dominated that landscape, the time when nature was “pristine” is impractical and unrealistic. Marris, instead, leans toward a system of conservation where nature and man coexist and where conservation takes place everywhere. Nature sure is no longer natural, then, according to her, why should we make the futile effort to change something that is ever changing by nature.
The author first addresses the difficulties of creating these “pristine” areas and the massive efforts needed to create “islands like the past”. One project the Australian Wildlife Conservancy was working on was returning the condition of a part of the Australian outback to the time when humans first colonized the continent. The creation and maintenance of such a place requires an enormous effort to evict all the invasive species including human and to erect walls and fences around the area. The Sanctuary, as the Australian termed it, was meant to sweep away all the domestic species that had been introduced by human a long time ago, such as cats, rabbits, goats and foxes. The violent methods that were enacted were aimed toward considered “invasive” entities including remaining human, like in the Yellowstone where Indians were “forcibly removed” from their land. The author thus illustrates the great amounts of work, unethical however they maybe, needed to achieve pristine nature.
I believe that at the beginning of her book, Emma Marris makes many strong points against the current way of nature conservation. I favor her opinion about people trying to conservation areas for the sake of preserving nature alone. They don’t account for many external and internal factors, including the fact that nature has already been modified and humans have been included as part of nature. Instead we should preserve nature the way it is and not try to revert it back to a previous “baseline” that we humans have set for it for the status that nature should be in, according to our own limited opinion. Changes will definitely occur no matter what, changes that will alter the species and land in the ecosystems, and not by the hands of humans. Conservationists have to accept these facts before moving on to the real mission of conserve it.
“But it was always nature”
Emma Marris lays out her argument clearly from the first paragraph of Rambunctious Garden: Saving Nature in a Post-Wild World “We have also lost nature in another sense. We have misplaced it. We have hidden nature from ourselves” (Marris). While the “carefully managed national parks and vast boreal forest and uninhabited arctic” (Marris) belong to nature, New Yorkers take for granted the man-made surroundings of the city and the “invasive” pests. These quotidian sights certainly fit in the umbrella term of nature as much as the next wilderness. As comprehensive as nature can be, it can no longer be “pristine” (Marris).
Much of the ruin and decay can be attributed to the human expansion. The effect of human development upon the earth cannot be ignored. Humans bend the environment to their will and in the process affect ecosystems around them. For example, “bobcat families move into foreclosed homes”, “Yellowstone moose birth calves” near human activity, and songbird reach “full throat to car alarm sequences” (Marris). Marris does not appear to be shocked by the adaptation amongst wildlife. Humans recognize the extent of their effect include “climate change, species movements, and large-scale transformations of land” (Marris). The next step would be to realize our role in this new ecosystem then take action by conserving the wilderness and even transplanting it to cities. Conservationists strive to achieve a harmony between lost wilderness and current ecosystems. To “find beauty in nature, even if signs of humanity are present”(Marris) would be my goal.
Conservationists work towards returning to a baseline within an area. Restoration falls under our ethical responsibility because “we broke it; therefore we must fix it” (Marris). Leaving the area better than its existing condition would improve the ecosystem. First, conservationists revisit a baseline. Then, an area undergoes a transformation by recreating water bodies, replacing species, and reconstructing habitats. What is important to note is that this ecosystem is nature despite being man-made. Nature constantly changes, even without human hands.
Marris’ definition of nature shatters preconceived notions of nature in mainstream media. I occasionally daydream because of my wanderlust for lush forests and distant wilderness. This “nature” no longer matches the current definition. I can appreciate her point that nature is omnipresent and the future lies in restoring as many baseline features in our ecosystems, be they urban or rural. Our heavy human hands have pummeled our dreams of a “virgin wilderness” and perhaps it might be the best to recreate bits and pieces of an earlier ecosystem within our modern city. My favorite example of this ideology being put into practice exists in Chelsea, Manhattan. The High Line runs from Gansevoort Street all the way up to the West 40’s. Real estate development companies reconstructed this dilapidated elevated railway track into an urban park filled with a diverse species of native and non-native wildlife. I can come to terms with this kind of unobtrusive nature that does not mirror the wilderness but embraces it.
Rambunctious Gardens Chapter 1 and 2
Rambunctious Gardens by Emma Marris talks about how the conservation of nature is unsuccessful using current methods. Marris believes that restoring effected areas to “baseline” is ineffective. She states that there isn’t a place on the Earth that hasn’t been affected by humans. “We have stirred the global pot,” she says (Marris 10).
Since nature is always changing and being affected by everything around it, it is almost impossible to restore it to its “baseline.” Also, nature has its own way of changing nature. Volcanic activity in Hawaii affects the ecosystems present there. Like Hawaii, ecosystems need a fresh start to allow the species to grow without interference from other factors. Usually, the removal of certain existing species can be lengthy. There just isn’t enough participation from people in order for this restoration to be a quick process.
Marris visited many restoration projects such as the Australian Wildlife Conservancy and the Scotia Sanctuary. Such projects require a lot of effort to begin and complete. For many of these projects, invasive species are first removed so that the original species have an opportunity to grow. Human beings were included in the species that were removed. This is an extremely difficult endeavor to partake especially with all the obstacles. This proves how ineffective current conservation methods are. Even though some results can be observed, it just isn’t strong enough to bring about dramatic changes.
Marris believes that nature should be preserved through this idea of a rambunctious garden. The rambunctious garden includes nature everywhere. This includes places in the city such as trees on the sidewalk and the backyard of a suburban home. If everyone took the effort to help protect nature, they should start with the nature that surrounds them already. This project will require less effort from people. This only holds true if everyone participates to protect the nature around them. The money and time spent on restoring areas to their previous “forms” is a tedious and ineffective strategy.
Even though Marris believes that the idea of a rambunctious garden will help us preserve nature, I still believe that it will be futile. The rate at which humans are affecting the ecosystem is too drastic for such small changes to make an impact. I do agree that it is a good step to begin with and can set the foundation for environmental protection projects in the future. Most people have accepted the fact that restoring nature is a lost cause. I also believe that protecting nature is far fetched due to the selfish nature of mankind. It’s a pity that nature cannot be appreciated as it was. However, trying to protect the very little nature around us isn’t going to change the majority of the ecosystems throughout the world.
Marris 1 & 2 – 9/4
Emma Marris immediately presents her standpoint in the fundamental environmental debate with the title of her book, Rambunctious Garden: Saving Nature in a Post-Wild World. Though “rambunctious garden” may seem like a paradox at first, the concept is fairly easy to grasp. “Rambunctious” as in letting nature run its’ course and “garden” as in allowing humans to oversee and manage. Marris states that this notion “creates more and more nature as it goes, rather than just building walls around the nature we have left (3).
In “Weeding the Jungle”, Marris calls on history, statistics, and her own personal experiences in order to put into perspective how the natural world has changed at the hands of humanity. Additionally, Marris presents the notion of a pristine wildness (another paradox) and modern efforts to recreate it. She describes pristine wildness as a cultural construction of an idealistic world (15). It is impossible, Marris argues, to create a pristine wildness unaffected by mankind. Numerous difficulties prevent us from doing so: disagreements on baselines, sparse or non-existent information on what was present, extinct animal and plant species, atmospheric disparity, etc. Still, the pristine wildness approach dominates conservationists. Marris advocates that is only when that ideology is dispelled and modified that we can move forward. Marris also suggests that, depending on the needs and wants of people, “forests…can be managed to achieve a smorgasbord of alternative goals” (13).
The “Yellowstone Model”, the views and writings of past conservationists and romantics and their contrasting views are presented. Marris says, Americans “perfected and exported the ‘Yellowstone Model,’ based on setting aside pristine wilderness areas and banning all human use therein, apart from tourism” (18). This model has set a precedent of conservation, prompting other countries with “lots of land inhabited by few people—or by people with few rights” (25) to follow. The caveat of the Yellowstone Model is that it requires land to be “untouched”. This leads to the forcing-out of indigenous people, which we first saw in the Conservation in the Anthropocene article. Marris builds on this, stating that forcing native people out is ironic, as “their land had sufficient nature to interest conservationists in the first place. (26).
Marris, instead of holding onto accepted theories against human intervention, creates a unique approach that embraces humanity. I agree that trying to restore places hundreds or thousands of years back is fruitless and that we should look to the future. While I believe that saving species from extinction is necessary, creating and maintaining exclusive havens for them is not the way to go about it. Not only do these refuges require a lot of time and resources, but also sheltering and isolating species is what led to the demise of many (6). The belief in a pristine wildness may be the ideal for many, but it is far from realistic in the world that we live in. Humans have altered the world too much as is to return to such a state. Marris put it best when she wrote, “layering goals and managing landscapes with an eye to the future, rather than the past, is the cutting edge of conservation” (14).
Rambunctious ch. 1-2
In Rambunctious Garden, Emma Harris’ main point is that society’s ideal of “nature” is ill-conceived and it needs to change in order to make the best of the opportunities open to us.
She claims that we generally think of the “virgin” and “pristine” as true nature (2-3), while those ecosystems brought about by man are not. These are fair claims, and she traces the birth of these ideas from the 18th and 19th centuries, reviewing how it slowly developed from thinkers such as Emerson, Thoreau and Muir (32-34). She makes it clear that these ideas have been manufactured in human minds and are not absolute principles. The Yosemite chapter also gives much support to the argument that keeping an ecosystem aligned with its “baseline”. A healthy ecosystem cannot be captured in a snapshot of a single moment, but is subject to shift according to Earth’s ever-changing conditions and surprises. Not only this, but life itself has already accounted for what we would consider “disturbances”, as evidenced by Harris’ example of seeds that need a recent forest fire to grow.
The mindset that Harris pieces apart is a paradoxical one where humans simultaneously shame themselves for human imperfection into Mother Earth and bestow themselves with the responsibility of “restoring” the perfection that once was, because we are able.
We consider humans to be so alien to “nature” that any change we bring is “degradation” (24). Humans are outsiders, trampling on the goodness of nature with a mixture of clumsiness and evilness. The idea is that anything we influence is the very opposite of nature. However, we also feel that we are so influential and powerful that we are compelled fix the problems we have wrought and bring about “restoration”.
I, like Harris, believe that this traditional style of thinking is both impractical and purely a cultural product. However, I am wary of Harris’ confidence that we are able to be responsible gardeners of the “rambunctious garden” Earth has become. It’s my impression that she is not just merely suggesting that we stop trying to aim for repairs but begin developing our own ecosystems (something only hinted here, but the chapter titles are telling). It is true that we often give exaggerated significance to nature untouched by man, but do we trust man to make the right and wise decisions necessary to build a better future? One of the points Harris brings up in the Yellowstone chapter is the complexity and constant flux of most ecosystems makes it basically impossible to recreate (let alone manage) how an ecosystem used to be. Who says that we know enough about Earth’s cycles and flora that we are able to create environments we have in mind?
There is reason why human activity has built up stigma. A book I have recently read, Collapse: How Societies Choose to Fail or Succeed by Jared Diamond, covers a myriad of examples of how humans have misjudged, created change in their environment, and brought their own demise. An example shared by both books is the rabbit and fox populations of Australia. While Harris focuses on the ridiculousness and burdensomeness of the attempt to rid the continent of the pests, Diamond delves deeper into other implications of their population boom. Rabbits are responsible for eating so much of Australia’s plant-life that native herbivores struggle to survive the competition, as well as domesticated animals that are vital to the country’s economy like sheep and cattle. The pests are not simply pests because they do not belong or ruin a “historical baseline”, but they literally eating away Australian’s income and well-being. The problem is so great that every year, a few hundred million dollars are spent on rabbit control alone. It is not unlikely that well-intended projects can become disasters.
While it is silly to consider traditional “pristine wilderness” as perfection, the underlying (and more powerful) notion is that nature has gradually come to achieve that kind of balance over countless years. I trust that ecosystems can and will find new balance as humans introduce new species and tinker with finding the “better” and “best” combinations. But that process may not necessarily go as we imagine. I agree with most of Harris’ points but I do feel that there is a certain degree of security we can find with traditional protected lands as compared to human ventures.
Rambunctious Garden Ch. 1 & 2
In the past couple of years, human development has increased exponentially and has touched upon many aspects of the Earth. Thus, the effects of the development has increased exponentially. To match the effects of their development, humans have increased the concentration done on conversations. But chapters one and two of Rambunctious Garden questions as too how we have misinterpreted the methods and thought processes of these actions. What we see as nature is something that is not touched upon by humanity. That is why environmentalists and conservationists are trying to reach baselines, which is “a zero point before all negative changes.” However, Marris believes that there is no such thing. Instead of thinking that way, Marris quotes, ” We can find beauty in nature, even if signs of humanity are present.”
Marris expresses her thoughts on baselines in chapters one and two. She writes, “ecosystems are in constant dance, as their components compete, react, evolve, migrate, and form new communities.” It is nearly impossible to look back in time to see how the environment was like beforehand. Even through using all the available resources like fossil pollen records and climate information, we still can not see what it looked like thousands of years ago. She also points out that, ” A historically faithful ecosystem is necessarily a heavily managed ecosystem. It is not the “pristine wilderness” many nature lovers look to as the ideal… If we define wild as “unmanaged,” then the ecosystems that look the most pristine are least likely to be truly wild.” As we live in a world heavily operated by humans, it is very unlikely to find an area that is untouched. And as we block off areas for conservations, we are still being involved in the process of changing the area to before humans changed it.
Another idea that Marris expresses is the definition of “nature.” People picture nature, they see those magazine pictures of forests, deserts, and oceans. However, people fail to realize that nature is all around them. The small park a few blocks down from your house is also nature. We are too focused on our own definition of nature that we fail to recognize the nature surrounding us. We think we live in a place isolated away from nature, and feel the need the travel away from the city to experience nature, when it fact it is always beside us.
In chapters one and two, Marris comments on the traditional views of conservation. She wrote, “This faith that native ecosystems are better than changed ecosystems is so pervasive in fields like ecology that it has become an unquestioned assumption.” And she ends with, “The cult of pristine wilderness is a cultural construction, and a relatively new one.” People think that nature is always better than what people themselves have made throughout the years. I agree with Marris and her views against the traditional method of conservation. People think on extremes, whether it is their definition of nature or in trying to go back to the baselines. We need to incorporate new methods in embracing humanity’s work on nature and work from their in finding new methods of conservation.
Rambunctious Gardens- Saving Nature in a Post-Wild World chap 1&2
Emma Marris’s novel Rambunctious Gardens- Saving Nature in a Post-Wild World suggests the readers to see the nature through a different view. In the first chapter, Marris introduces here thesis and the current state of the ecologists and their conservation projects. One of the major goals of the ecologists is to return nature to its “baseline”. People strive for the most natural state of the ecosystems. The term “baseline” refers to a most basic state of nature. However, Marris argues that there is no way for the nature to be pristine. It means by that nature changes even without any human interference. So here is my question? What is the base or the standard for nature? Is there a real pristine nature? My answer is no. The nature has been changing from the beginning when there were no humans. The other aspect of nature such as animals and climates has evolved and changed each other. Yes, it is the humans that destroyed the nature and made problems. However, my point is that it is pointless for the humans trying to restore the damages. One of the past two articles states that the speed of nature’s restoration is unbelievably fast. Therefore, what human needs to do is not to disturb the nature while it restores. (Which seems like impossible at this state.)
Current conservation projects isolate the nature from the human society. The ecologist hopes for the protected area to return to its pristine state since there is no human contact with the land. However, the conservation project drives people away from the homes. Eliminating people from there traditional habitual area to protect lands seems hypocritical. Ecologists strive for the pristine nature, however, the protected area are basically man-made. Humans control everything inside the area. So, is protected natural area such as Grand Canyon and Yellow Stone Park pristine?
Later on in the chapters, Marris introduces the readers the idea of “rambunctious garden.” In rambunctious garden, humans and nature live together as one. Marris states are nature and ecosystem is everything between our very own backyards to the protected area. This statement criticizes current operation of conservation projects as it only focuses on the protected areas. What ecologists must realize is that it is important to protect nature that resides with human in the urban ecosystem. Therefore, the rambunctious garden is solution to the current problems of the ecosystem. Since there is no pristine or the baseline of nature, what we can to is to make sure the nature survives with the existence of humans.
Weeding the Jungle and The Yellow Stone Model, Chapter 1&2
Emma Marris’s Rambunctious Garden is a book that describes a new type of conservation that we should adopt instead of trying to restore patches of our nature to pristine ecosystems. Her main point focuses on how we are losing nature by misplacing it. We should not look at nature as pristine ecosystems, but as rambunctious gardens.
Marris points out why recreating pristine ecosystem is almost impossible. First, there is no pristine wilderness on planet Earth in 2011 (2). There is no way to preserve pristine if there’s no more “virgin” areas untouched by human influence. We stirred the globe too much that it is difficult to reverse the damages and changes we had done on our planet. Second, there are few or no spots on earth with ecosystems that remained unchanged for more than 12,000 years (34). Even without human influences, climate changes and natural disasters like wildfires can change an ecosystem dramatically. Yellowstone, a model for many preservation efforts in the world, is “non-equilibrial”. The fire in Yellowstone in 1988 was an example. Species can be wiped out by one fire, where they can be recovered or be replaced by new species that better adapt to the new ecosystem created by the disaster. Third, secular climate changes occur constantly without human input, which provide constant changes in ecosystems. We are currently in the interglacial period, where temperature is getting warmer on its own and ecosystem is constantly changing. Setting a baseline and trying to counter all the human influence and natural climate changes is ineffective. Some pristine species, according to the set baseline, might not be able to survive and grow in the climate and the environment of their ecosystems today
Marris also gives some examples of recreating pristine ecosystem to prove it as time consuming and ineffective. Recreating pristine ecosystem includes getting rid of the invasive and undesired species in an ecosystem to allow the “original” species to grow. Tony Cathcart took eighteen months to conduct the removal of introduced animals in a fenced block in Scotia Sanctuary. It took more than 6 years to remove introduced species in about thirty miles of ecosystem. As Marris states, “… unless the whole country decide that its number-one priority is ridding Australia of feral animals, these little fenced islands are all that pristine focused conservationists can hope for” (11). Recreating pristine ecosystem is ineffective in terms of time and money. Also, recreating pristine ecosystem includes forcing the inhabitants to evacuate the land they live in. It creates problems and inconveniences to inhabitants that are doing little damages to the nature. On the other hand, recreating pristine ecosystem by getting rid of thousands of species is doing way worse to the nature than what those inhabitants ever did.
I agree with the case Marris presents in the chapters about having rambunctious gardens instead of pristine ecosystems as the best conservation method. As Marris describes it, “Rambunctious gardening is proactive and optimistic; it creates more and more nature as it goes, rather than just building walls around the nature we have left” (3). I think Marris is saying that we should work with nature instead of restoring our environment to its pristine look. As she states, no single goal will provide for a well-rounded conservation program (14). Thus, a conservation program should be a collection of alternative goals (13). Part of the project can be cleared of undesired species to teach people about its ecological history; part of it can be a protected area for endangered species, another section can specialize in species that are important to the culture of its people and economics of its area. I think doing conservation projects as such is one of the better ways in achieving conservation, without damaging the true nature to recreate the pristine nature.
The Necessary Pause on the Rambunctious Garden
For the past few centuries mankind has made substantial efforts in shaping the landscape and environment to fit his will. This in turn caused a separation of nature: that which is man-made and that which is naturally from earth, or more commonly known as nature. Since man operates in man-made environments, we view nature as something distant and untouched by man. For this reason, when we attempt to protect a piece of nature, we isolate it from mankind. This inaccessibility allows us to preserve nature rather than change it into something we’d prefer it would be, like a parking lot, shopping mall, or office building.
However, in her book “Rambunctious Garden,” Emma Marris states “our mistake has been thinking that nature is something ‘out there’ far away…somewhere distant…somewhere faraway. This dream of pristine wilderness haunts us. It blinds us.”(1) She recognizes nature as everything around us, from the forests in Hawaii, to the battling elk in the Yellowstone, to the pigeons on the streets of Manhattan.(2) Because of her perspective on nature, Marris is against the idea of a “pristine nature” and believes in the notion of a “rambunctious garden,” where humans control the environment and manipulate it.(3)
However, since she believes that no piece of the environment is pristine, because humans have touched nature in some type of way, then her idea has already come to pass. Over the past few centuries, mankind has taken an active effort to inhabit more land and shape it as he pleases. Since we are living in a human-operated world, the environment already bends to our will. With this power though, we have shown to be irresponsible and not ready for that kind of power. With many dying species, a growing population, rampant pollution, global warming and the inability to provide for other humans in certain areas of the world, humans aren’t capable of coexisting with nature, at least not at this point in time.
For this reason, environmentalists and conservationists pursue the idea of isolating specific pieces of nature from the public. If there were nothing to stop us from entering a piece of land, then we would simply shape in however we would like. Throughout history we have shown that our pursuit of growth and prosperity has made us inconsiderate to natives of the land. This includes, plants, animals, and even other humans. Because of this selfishness, if we were to remove the barrier between the “far away nature” and the man-made then it would eventually result in the elimination of the nature less tainted by human interference.
Hence, while humans ultimately do play a role in the future of nature, we have proven we can’t completely coexist with it at this point in time. Until we can resolve the issues we have created, or amend them to a certain extent and prove that we are capable of handling the responsibility of nature’s future without abusing our dominance over it, we will never be ready to achieve Marris’s goal of a “rambunctious garden.”
Rambunctious Garden Chapters 1 and 2
In the first two chapters of her book Rambunctious Garden: Saving Nature in a Post-Wild World, Emma Marris introduces us to her main thesis and reason for writing this volume. It seems to me, that her main focus of the book is ecosystems and the misconceptions people, especially leading conservationists, have about them. A point she makes is that nature is not something that can be easily shaped and molded to fit standards established in the past. A practice that she disputes is trying to restore ecosystems to the conditions they were in years ago. She doesn’t think that this is an action that has any real benefit or foreseeable success. It is very hard to accurately paint a picture of what a particular ecosystem looked like more than a century ago. It’s also no small task to root out the nonnative species and reintroduce species that haven’t been in this particular area for years. In Marris’ mind, the new face of the ecosystem that has developed over the years is just as much “nature” as the landscape that existed years ago. Nature itself is constantly adjusting to this ever-changing world so our perception of what nature is exactly should change and be flexible in just the same way. A concrete, outdated conception of nature is something we as a community should not dwell on.
Another concept that seems to be a theme in Marris’ writing is that pristine nature is not something that we should necessarily strive for. Marris makes the point that nature isn’t only the untouched ecosystems in the world, devoid of human life. Nature is everything from a garden in a backyard to the Grand Canyon. Rather than focusing on the protected areas of the world (only about 13% of Earth’s land is protected), we should realize that there is nature all around us everyday that should be cherished and protected. Over the years we have developed this illusion, especially as city-dwellers, that nature is something far away and mysterious. We feel as though we need to take vacations and go out of our way to experience it, when it is really around us every day.
Overall, Marris seems to be making points against traditional ecological views of nature. The current methods and ideas surrounding nature preservation seem to be outdated and in need of an overhaul. I think that Marris expresses her thesis and introduces her argument in a clear, concise, and strong manner. I found it very easy to interpret exactly what she will be trying to do in this book from the first two chapters. A strength in her writing is her use of sources and statistics. The book is full of references and data that make for a stronger and more reliable argument. The book is not merely a collection of Marris’ thoughts and arguments about ecosystems and preservation, but a structured and supported argument that the reader can more readily trust and assess.
Marris Chapters 1 and 2 Response
In Rambunctious Garden: Saving Nature in a Post-Wild World, Emma Marris makes it clear that current conservation methods are inefficient and do not work in our world. Within the first few pages, Marris already tells the reader that nature is not “pristine” and it is always changing. She claims that humans already control most of the whole Earth and people should “admit [their] role and even embrace it” (2). In other worlds, people should not depend on the old conservation methods because we have an even greater influence on the world now. This is similar to Kareiva suggesting everyone to not depend on the outdated conversation methods. Marris further adds that nature is more than just “untrammeled wilderness” since nature is almost everywhere in this world.
Marris also shows the reader how the old conservation methods do not work. According to Marris, many people want to transform an area of land into something similar to pre-human existence. Marris often refers to this as the baseline. The baseline is assumed to be “a time in the past or a set of conditions…before all negative changes” (3). However, there is no actual baseline because nature constantly changes. Yellowstone Park is often viewed as one of the most “pristine” places in the world, but it “has always been in flux.” (27). The idea that nature keeps changing makes it impossible to set a baseline because there was never a “zero point” in the first place. Ideally, this zero point should be where everything was in a stable equilibrium, but that is impossible according to Feng Sheng Hu. Marris even argues that if people continue to hold onto the baseline idea for Yellowstone, they may have to make the baseline “under cold circumstances” (35). Of course, this will be very difficult to do with the increasingly warm climate.
I agree with Marris’s case on nature. Regardless of human interaction, nature is always changing and reacting to its surrounding. For this reason, it is near impossible to change nature into a “pristine or untrammeled wilderness.” In fact, Marris calls it a paradox. “A historically faithful ecosystem is necessarily a heavily managed ecosystem… If we define wild as ‘unmanaged,” then the ecosystems that look the most pristine are perhaps the least likely to be truly wild” (12). While managing ecosystems are difficult, Marris argues that managing ecosystems to avoid a large number of extinctions is possible. To be able to do this, people should stop depending on the old romantic view of a “pristine nature” and start embracing the fact that nature is almost everywhere in this world. In addition, people need to accept the fact that humans are part of many ecosystems. This will change the way people think and perform their conservation method and it will also change the way people react to the term “pristine wilderness.” I think Marris summarized it best by saying to focus on “future, rather than the past, [as] the cutting edge of conservation” (14). Otherwise, we are wasting resources on an unachievable goal by attempting to reserve the past.
Rambunctious Garden Ch.1 and 2
In the first two chapters of her book “Rambunctious Garden: Saving Nature in a Post-Wild World,” Emma Marris argues that the idea of nature that most conservationists have is an inaccurate one. Marris argues that creating protected areas that resemble a time when man had not dominated that landscape is impractical and unrealistic. Instead, Marris favors a system of conservation where nature and man live together and conservation takes place everywhere.
Up until recently most conservationists have been following the “Yellowstone Model” (Marris, 18). This is the idea that wilderness areas should be set aside in conditions that the areas had before humans came to the area, an idea that was made popular thanks to John Muir and Theodore Roosevelt who were natural park advocates. Yellowstone was one of the first national parks in the world and lead to the creation of national parks in other countries. In the 1960s, A. Starker Leopold and other scientists visited national parks in the United States and published the Leopold Report which stated: “as a primary goal, we would recommend that the biotic associations within each park be maintained… as nearly as possible in the condition that prevailed when the area was first visited by the white man” (Marris, 24). The Leopold Report had a huge influence in the conservation community and conservationists strived to meet its standards.
Marris argues that conservationists that follow this standard fail to take natural change into account. Ecosystems often experience natural disturbance such as fires or droughts. In addition, ecosystems have to deal with secular climate change. The climate has shifted between cold and icy periods called glaciations and warmer periods called inter-glacials. Because of all these natural disturbances, ecosystems do not have a natural equilibrium, or balance of nature, on which conservationists should base their visions for natural parks. Instead, ecosystems follow stochasticity, or randomness. Professor Hu from the University of Illinois even stated, “There really isn’t one unique state of natural conditions for any given landscape. What is more realistic is to set a range of natural conditions” (Marris, 31).
Scientists are slowly starting to realize that they should manage natural parks in a way that builds resiliency rather than creating an ecosystem from the past. Marris and like-minded scientists realize that the ecosystems that man has created will still serve the same functions, such as storing carbon and harboring species, that the old ecosystems played. The ideas of Marris and the new conservationists can be summarized by a quote from Marris: “Layering goals and managing landscapes with an eye to the future, rather than the past, is the cutting edge of conservation, but some ecologists, conservationists, and citizen environmentalists just aren’t there yet” (Marris, 14).
