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?

Polluting food
We are very rich, so we want to consume perfect food and this is really polluting. For example: we want to have perfectly round apples, withou bruises,... . Certainly the processes for do this is polluting. One year ago in my country (Switzerland) a chain of supermarket sold apples "normaly" (with very less chemical treatment: the apples were not perfectly round,had bruises,...), nobody bought it and after not very much time the sale interrupted.
