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?

Transportation
As an international student, I will shuttle between two countries always. Thus, I must use plane to travel. However, the plane will release a lot of carbon dioxide or carbon monoxide and these will cause the global warming. Scientist should develop some new transportation which use electricity to run like Pneumatic Tubes which is as fast as the plane but protect the environment more.
