Students from around the world calculated their class mean and standard deviations for their footprints and posted them on our world map.
Do you see differences across the globe? If so, why do you think those differences exist?
Did you use the calculator to try to reduce your footprint down to the average from a citizen of another country? What changes would you have to make to lower your footprint in this way? Are you going to try and take some of these actions in your daily life?

Family Footprints
While calculating my family's footprint I noticed that I had a large part of my Co2 emissions come from food and food waste. This surprised me because I thought my family was pretty good at making sure what we ate was good for the environment. But I forgot to consider one factor, transportation. Many foods we eat say they are organic or sustainably sourced, but this doesn't cover transportation. Much of over food, like fish, can travel over long distances to end up in supermarkets and our houses. From this I learned that I can do more to ensure my food is better for the environment, that I should be looking for locally sourced foods in addition to organic.
