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?

Self-sustainability
Creating a self-sustaining environment in your own backyard decreases the negative impact you have on the world. Having your own vegetable garden or orchard both provides nutrition for you and gives back to the Earth. And after a meal, you can compost the uneaten food and use it to plant more fruits and vegetables.
