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?

Carpool is the way!
I really think that a big part of the problem could probably be easily solved. How? With the public transports and the carpool! I get to school by bus and I try to avoid using a car or a motor scooter if it's possible. My friend gets to school by train and by carpool with 3 other people. It could get difficult, but if you really care about the environment, you should totally try these methods out instead of using your vehicle.
And a huge difference is that you are never alone! 
I totally agree with you, these methods also have other advantages, such has not having to find a parking spot (if you use public transport), if other people do carpool or use public transport automatically creates less traffic and they are both more economical. So, if you can, why not giving it a shot?
