Ecological Footprint: Creating a Sustainable World

Going into this activity, I wasn’t even slightly worried that my footprint might be large. I don’t eat meat, and I take public transportation regularly. I really try to be conscious of my energy use. These things made me feel like an environmentalist extraordinaire. I was wrong.

According to this calculator, to sustain my lifestyle worldwide we’d need 4.6 Earths. Granted this is below the American average, it’s still not good – especially in light of what I thought it was. In terms of acreage, my lifestyle takes up 20.5 of global acres, compared to the average of 17. So in this regard, my footprint is actually worse than that of the average American. Most of the acreage is used by energy land.  To me, the fact that my acreage is more than the average American is even more disturbing than the amount of Earths it takes to sustain my lifestyle. This is really eye-opening.

My ecological footprint consisted primarily of services. I’m not entirely sure what this means exactly, but I’m positive that there are many changes I could make in my life to shrink my footprint. I could start eating more locally grown produce, and preparing more of my own food – which, as a college kid, I’m not the best at. I could also cut down on my use of electricity and my consumption of new gadgets, which take a lot of resources to make, and a lot of land to produce. I could encourage my family and friends to do the same, so that our household and others live more sustainably.

According to my graph, eating large quantities of meat has the greatest effect on ecological footprint. It follows that if everyone around the world were to switch to a vegetarian diet, it would be conducive to creating a much more sustainable society. In conjunction with using mass transit more and using energy sparingly, this could create a more sustainable world. Of course, these individual choices are important, and mass awareness is key – but to change the course of the world definitively, more must be done. Industry is the cause of a large amount of the environmental issues we are seeing today; we either change this system, or resign ourselves indefinitely to environmental degradation. This is something we all need to come to terms with, and commit to taking action against.

 

Ecological Footprint Analysis (will do in class 12/12)

In class on 12/12 we will be discussing what it means to be sustainable as well as what levels and scales we need to act to achieve sustainability: individual, local, global. You will then complete an ecological footprint analysis and vary the parameters to test the difference you could make to reduce individual carbon footprints.

Ecological Footprint Analysis
footprintnetwork.org/en/index.php/gfn/page/calculators/
1. Calculate your carbon footprint and how many planets and acres are needed to sustain a lifestyle similar to yours (use the detailed parameters).
2. Pick three parameters to maximize (e.g. diet, transportation, energy) and determine how that changes the footprint. Make a bar graph that shows how many planets OR acres you need based on the parameter maximized (also include your original calculation).

(NOTES: Can measure transport distance with Google maps;  NYC gets 11% of energy from renewables)

Discussion QUESTIONS to answer in you blog post:
1. How does your original footprint compare to the country average (US per capita is 5 planets and 17 acres)?
2. What changes could you make and what level would it make a difference, it any? Include your bar graph.
3. What do you think, overall, we need to do as a society, as a world, to really make a more sustainable society?

Readings and Podcast for 12/12 class- Also bring Computers!

You have two readings (one longer and one very short) and a 20 minute podcast to listen to for next class.

This first reading is going to provide the basis for our last discussion on urban biodiversity 🙁 in class. It is a new study on- you guessed it- arthropods!- Please at least read the abstract, the methods, and examine the figures (there are also some popular articles about it online). It also serves as a good model of the kind of scientific writing you all will be doing in the next couple of weeks for your projects. We will discuss what this study found, what they could have done differently, and what it means for urban sustainability.

The following pieces will be part of our class discussion on sustainability at the individual, city, and global levels.

Forget Shorter Showers, Orion Magazine. This is a short (2 page) piece basically saying that life changes at the individual level won’t make a difference in sustainability. We will discuss this idea, watch related videos, and examine your own footprint in class.

Finally, this is a 20 minute podcast on what we do and have done with all the poop generated here in NYC- an important component of urban sustainability- Enjoy!
