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?

Litter
Everybody knows that our environment today is endangered, but very few people want to know why and how to cope with this problem. Various forms of pollution are happening due to some careless human actions. Littering is one of them. It can lead to water and air pollution, land and soil pollution, and to many other unwanted effects. Litter has become a serious environmental issue nowadays. Of course, the majority of normal people know that littering is a negative thing. However, there are still lots of careless people who continue scattering their trash around. Litter can come in many various forms, starting from simple newspapers and proceeding to poisonous chemicals left from industry. People buy more and more unnecessary things every day, instead of reviving their old things.
