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?

Plastic bags pollute our environment.
Plastic bags don't seem to be a big problem compared to extinction of endangered species but they can cause a big problem to our planet. Bad thing about plastic bags are that they need hundreds of years to decompose. While they decompose they produce greenhouse gases which takes to global warming and kill animals. I have heard that some countries bannded plastic bags or even introduced tax on them. I saw on our seaside that people left plastic bags on the beach which is no good for birds and other animals. In m
In my opinion we all should use cloth bags or ecopaper bags so that we don't pollute environment and we should make people aware of the danger of plastic bags.
