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?

We should help our planet
If we cannot learn to use the environment carefully, very soon we'll have no world to live in. In my opinion, pollution can be stopped or at least reduced by using fuels which are low in pollutants, more complete burning of solid fuels, shift to using alternative forms of power such as wind power, electricity or solar energy and banning the use of nuclear power. The first reason why I believe these ways to be most effective ones is that industry and transport are the most important sources of all chemical pollution of air, water and soil. The second one is that banning the use of nuclear power will destroy the danger of radioactive contamination.
