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?

Life in the Earth
I think that nowadays the problem of pollution is very acute. The car and factories in and around our cities are giving off dangerous fumes. It is very dangerous for human health. People may have allergies or other diseases. Moreover, factories are polluting our rivers and lakes with dangerous chemicals. Fish are killed, rivers are contaminated. People drink polluted water and breathe dirty air. It is very bad for humanity and nature. We must prevent the destruction of the Earth and the death of all life. People need to take care and protect our Earth. All people are required to sort the trash. It is very important!
