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?

E-mail vs. letters
I think that [more] people should start writing letters again! Of course e-mail is more ideal for certain things, but it is not better for the environment than mailing paper letters. According to this article; http://www.nytimes.com/roomfordebate/20 … d-a-letter this is partly because of the fact that paper can be recycled, whereas e-mail cannot. Also, many non-renewable metals and fossil fuels go into sending e-mails.
