Footprint Calculations

1. My carbon footprint is 23.8 tons of carbon dioxide and this requires 22.4 global acres to sustain. This would be about five planets worth of land if everyone on earth lived the way I did.

2. This is a graph comparing my global footprint to the national average to the footprint obtained when three factors were maximized.

FINAL GRAPH

Discussion Continued:

1. My footprint is slightly higher than that of the national average if we compare based on acreage, but is the same if we estimate based on planetary land needed.

2. Since I depend on public transportation to get to school everyday, I don’t think this is something I can change for now. However, I do eat meat on a daily basis and if I could, I would try to eat less animal derivatives overall. This should decrease my footprint by about one to two average earths if everyone else lived the way I did.
3. As we have discussed in class, there is no one perfect solution to making the world more sustainable. There is always a challenge to determining what resource is “more worth” saving. However, I think that getting larger institutions to adopt some characteristically individual-based approaches to sustainability would be a good start. For instance, my family recycles, but it would be great if larger organizations like schools, supermarkets, office buildings, and hospitals, for instance, started recycling more regularly. I think it would also be good to encourage people to eat fewer foods that contain animal derivatives. These are practices that are usually held responsible by individuals, but if larger policy and institutions made more of an effort to promote these practices, I think we would be making a lot more progress towards living sustainably.

On Elephants and Introduced Species

The first display I observed was the “Forest Elephants and the Saline” display in the Rainforest section of the Hall of Biodiversity. This display appeared to give a general idea of how elephants served as a keystone species in the rainforest. This part of the exhibition contained information regarding specific species of rainforest elephants such as their relative body and population sizes. The display did not appear to try to persuade any specific opinions, but rather tried to give a broad overview of this topic.

The second display I observed was the “Introduced Species” and “Laws and Regulations” display in the Resource Center. This section of the exhibition put more effort into convincing the museum patrons to act a specific way. To bring attention to issues caused by humans’ interaction with nature (such as creation of endangered species, introduction of nonnative species, and subsequent disruption of ecosystems), this presentation showed a series of plaques that attempted to educate the readership. The language compelled readers to behave in a way that would not cause further damage to the biodiversity of the earth. The vocabulary placed a larger responsibility on the readers to act in an environmentally sound way and to even go beyond monitoring individual behaviors: “citizen action,” “humanity’s spread,” “disruption.” The panel also showed off a large quote stating, “the job of a citizen is to keep his mouth open,” as a direct call to action.

In the Forest Elephants exhibit, viewers tended to read the plaque descriptions briefly before looking at the plant and animal recreations behind the separation bars. Some of the viewers who stood near the built-in books would flip through some of the pages and skim the pages before leaving. Others standing near the video player would watch the video for a few seconds before promptly leaving. Commentary from the visitors also proved that they did not learn very much from the display. Much of the conversation about the display was either a direct observation of what was in the display: “Look, elephants!” “I think I saw a fish.” Other conversations were entirely irrelevant to the contents of the exhibit: “Where did she come from?” “Ahahaha; that happened to us.”

Visitors interacted with the Introduced Species display  in more meaningful ways than with that of the Forest Elephants. As there were small computer-like devices built into the display, patrons spent more time at this display and also had more deliberate interactions with the display. Some museum-goers stopped to press buttons on the electronic device. Others would pause to read the descriptions on the wall while their fellow museum-goer looked at the information on the electronic screens. This may be due to multiple factors.

For one thing, the two atmospheres differed greatly. In the Forest Elephants exhibit, the lighting was very dim; in fact, it was so dark I could not even really see the writing on my notebook. There was enough light to read the description plaques, but not enough to see very far into the actual artwork of the display–especially if your eyesight is not the best. In stark contrast, the Introduced Species exhibit was very well-lit. The display was either placed on electronic screens with bright backgrounds or on light-colored non-electronic backing with highly contrasting font colors. Though I very much enjoyed the laid-back atmosphere in the Forest Elephants exhibit, it was less enticing to read through all the material and look for particular animals in  the display when the lighting was so dim. It was much easier to examine the display in Introduced Species.

The content also made a difference. In Forest Elephants, one was provided only with relatively non-opinionated data. There was no real argument being made–or at least not one that was easily interpreted. A clear argument, however, was presented in the Introduced Species display. The creator(s) chose a position and supported it with data that could be potentially very emotionally compelling–depending on how involved with this issue the viewership is.

Though more interactive displays are not always a better solution, I would say that having an interactive element added to the elephants display would help a lot. Increasing the amount of light a little bit would probably also help. The viewers who did stop to examine the displays did so mostly when there was something that required direct participation, not just observation. One thing that I did like very much was that the video in the elephant display had clear audio that was loud enough to hear when at the display but not so loud that it would disturb viewers at a nearby display.

The Hall of Biodiversity had a plaque in the center where it was not well lit.

BIODIVERSITY PLAQUE

It was a large paragraph that eloquently explained the concepts of biodiversity and protection of biodiversity. However, it would probably have served its purpose in conveying the conservation message if it was placed in an area where more people would read it–perhaps somewhere near the entrance of the hall. Overall, however, the Hall of Biodiversity is effective in educating the public. I liked the fact that the environment could be relaxed but simultaneously educational. There was no need for overly didactic chair-lecture-board methods for patrons to learn about the different species on this earth and the different ways that they could help save what biodiversity remains.

I really hope that people who go to this hall learn about the biodiversity message. I hope they take this lesson to heart, because as my fellow classmates and I were leaving, we overheard one visitor loudly declare, “I don’t care about animals.”

Cruelty-Free Cuisine

The BBC News: Science and Environment covered an article about the recent regulation in trade of shark and manta ray meat and fins. The article mostly maintains a seemingly neutral position on the issue of over-harvesting shark and manta-ray populations for their fins and meat; however, analysis of why this article was written and the word choice shows that the author is probably anti-shark and manta ray harvesting.

To begin,  the title of this article “First Ban on Shark and Manta Ray Trade Comes into Force” just about sums up the article’s position: neutral with slight inclinations towards banning such trade. I say this because if the author Matt McGrath was not even slightly interested in preserving the shark and manta ray species, he would not have covered this story, nor would he be the Environment Correspondent for BBC News. He would also not be using terms like “trade,” which for some, can elicit images of the brutal hunting of animals for bushmeat and prized resources like ivory and furs.

Going into the article, I assumed the author would don the position that shark fins in particular should not be harvested. You may already know that the method by which hunters harvest shark fins is by pulling a live shark up to a fishing boat and using a machete of sorts to slice off all fins from the shark. Since sharks need to stay motile to breathe, the moment they stop swimming, water and oxygen stop passing over their gills and they suffocate to death. I believe that personal bias may have influenced me to think the author would side with the sharks on this one. McGrath discusses some statistics that show how the shark population is at risk due to over hunting, so there is still a chance he is for the protection of sharks.

BBC is a pretty well-known broadcasting organization, but the fact that there are no citations for “scientific estimates” and certain other statistics makes me skeptical of how accurate this article really is. The title is also improperly capitalized, and one would think that in a large company like BBC, there would be some level of proof-reading. At the same time, the author posts his face, name and professional twitter, making him responsible for the content he has posted in this article and, reasonably, less likely to post false information.

The article mentions that the trade flourishes most in Hong Kong and China and this leads to a point for counter-argument. One could say that since shark fin is considered a delicacy in these two areas, it would be sort of culturally insensitive to put a ban on this trade. However, I believe that this is a weak argument, because there are foods other than just shark-fin and many Hong Kongers also agree that harvesting this way is inhumane and not worth causing suffering to all those sharks. In the end, the ban is not about cultural suppression; it is aimed towards preserving what species of sharks and manta-rays are still in existence so that they may support the food web of today and tomorrow.

It can also be argued that placing this ban will hurt those who depend on it do earn a living; but i believe that this, too is a poor argument. People can still trade sharks if they have a permit that certifies they are harvested “legally and sustainably.” It is not that the trade is being banned, it is that the over harvesting is being controlled.

In New York, there has already been a ban on trading shark-fin and I am glad that the rest of the world is staring to change, too. It is important to see that there is a larger picture that includes all species of organisms and that losing one does not only disrupt that local environment. It disrupts the whole network of nested relationships.

Overall, the argument was fairly weak. I felt like there was an attempt to provide sources for the claims made, but not enough evidence-based support was available. It made me cynical about an issue on which I already have an established opinion. Of course, I am always open to change if I am given new evidence, but this article does not say anything new, either. No real alternative conclusions are proposed and the consequences are not elaborated in any real detail. I am afraid I must say that this is not science.

Mosses at Bioblitz

On Sunday, I got to join the mosses group along with some other Brooklynites and explore the variety of species of bryophytes in the New York Botanical Garden. My group was given a guidebook and some small magnifying lenses to help identify different species. The magnifying lens was about a quarter in circumference and we were able to use it to look closely at the distinguishing details of the mosses.

Even though our guide informed us that the NYBG has one of the largest–if not the largest–collections of plants in New York, it was still quite fascinating to learn that there could exist more than three species of mosses in a single square inch of land. The moss specialist for our group explained that there are slight differences in temperature, substrate, and even moisture over a given square foot of land; because of this, the species of mosses that live on one side of that square foot can be entirely different from those on the other side.

To the untrained eye, the mosses will look almost identical; however, with the help of the guidebook and our moss specialist, we were able to identify over eight different species.

My favorite moss of the day was the Marchantia polymorphaWP_20140907_005This moss looks just like a little forest! The guide informed us that the palm-like structures aid this organism in reproducing. The base is where new plants sprout. There were many other varieties of mosses, (all of which have their own methods of reproducing and maintaining the species diversity in New York) but there was just not enough time to fully study all of. Even if the biodiversity in the larger community is still declining, it is at least being preserved in this area of New York; and I am glad that I was able to participate in examining the biodiversity–or at least for that of mosses–at this year’s Bioblitz.
