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?

Changing Transportation
Taking trains, busses, and other public transportation will make our carbon foot print less. It will lessen the CO2 emitted in the air. This is an easy change.
Yes, I think Bart is a good method of transportation because it also saves money and takes you to all the places you want to go. Bus is also very cheap and saves gas money.
