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?

Sustainable city
We need to make a lot of changes if we want a sustainable city. We want a sustainable city. Good changes that will help the planet. I think we should not cut trees. Trees suck in carbon dioxide and when you cut them down it releases it back into the atmosphere.
