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?

What would be the best way to reduce the CO2 produced by airplanes?
Make airplanes bigger =Less amount of "Lift Off"s but more fueld required for lifting off
Make airplanes smaller = less fuel required for lifting but more amount of "Lift Off"s
But if you make airplanes smaller then that will be more fuel going in the airplane because that will have to make more than one trip?
I think the best way would be to make airplanes bigger because more people could get on those planes which would cause less "lift off's" and prevent how much carbon dioxide goes into our atmosphere.
