First of all, there is an awesome site called worldmapper.org
that has a whole collection of cartograms, maps where the size of each country is not determined by land area but by another variable, from the basics such as population to more specific but interesting data such as patents granted, or in the case of the map below, ecological footprint.
Technical notes for this map.
Notice that this is total, not average, ecological footprint, which is why India and China are on par with the United States. They have larger populations and smaller average footprints than the Americans' 24 acres. If everyone lived like Americans, we would need over five earths to sustain us. Considering that I share a bedroom with two other people in a building that houses over a thousand people and that I don’t have a car, I thought my ecological footprint would be significantly below the average American’s, even if it was more than the world average. However, after calculating my footprint, I discovered that mine, at 25.6 acres, was not only larger than the world average, but also larger than the average American’s. Housing and transportation, two factors that I thought would take up much of footprint as they do for the average American, were not the biggest contributors to my footprint. Instead, my largest footprint contribution came from monthly goods and services, especially from my spending on education.
The footprint from college was bigger than any other category, including food, and was much bigger than any other single item on the list. This made me wonder how the footprint factor for education was calculated; what items were included? The buildings and grounds? The research labs and textbooks? I cannot imagine how going to college creates a bigger footprint than all of my food. I also wonder about using how much we pay for education as an indicator of its footprint. Do private schools have significantly bigger footprints because tuition is higher? Or is the responsibility for the footprint simply shifted from the government to the individual tuition payer? The way the footprint calculator is set up, the responsibility for the footprint lies with the individual who financed it, not necessarily who uses or demands it.
The process of calculating my ecological footprint brought up many questions for me. I realized how little I know about what contributes to my footprint. I had to call my parents to ask about our insurance and phone bills, and look up information about my dorm to answer many of the other questions. I take many of the material goods in my life for granted and never stop to question where they came from or whether I really need them.
The other thing I noticed about my footprint was that there aren’t many small changes I could make that would have a significant impact on my footprint. Producing less trash perhaps, or using a little less electricity might save a few square meters, but without changing my lifestyle, such as eating less or dropping out of college, my footprint won’t change dramatically.
There is, however, one change I could make now that would affect my footprint, and that is going vegetarian. My meat consumption accounted for over half of my entire food footprint, and accordingly I am trying out vegetarianism for my class project, and have just completed week one. Going vegetarian alone will cut four acres off of my footprint.
In the “medium” term, such as in the next few years, I plan to reduce my footprint by reducing my waste output and eventually moving into an apartment, where I will have more control over where my food comes from and what goods I purchase to use. While my short-term plan of going vegetarian may or may not last, I am confident that I will be able to reduce my meat consumption significantly, if not completely.
In the long term, after college, I would like to live in a city. While growing my own food may be difficult, hopefully I will be able to take part in a community garden or at least have access to farmers’ markets. Living in an apartment will reduce my housing footprint, and biking or taking the metro around the city will keep my transportation footprint low.
Overall, this process was frustrating and while I’m not entirely convinced it accurately describes my footprint, it was worthwhile and opened my eyes to many aspects of my consumption that I rarely considered. As I grow older and begin to settle into a lifestyle after college, aspects of the process of foot printing will influence the choices I make and the way I consume.
