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?

CO2 not just a problem for the planet
Hey everyone.
We always think that CO2 and the pollution are a problem just for the planet, but we don't think that pollution is a problem for animals too.
First of all we need oxygen, which is produced by plants, and if we keep polluting the world there won't be enough plants to reduce the problem.
The second point is that we are breathing a lot of harmful gases which come from cars and planes. Just think about the China, where there are a lot of people who go around their country with filter masks.
The last point but not less important is the Earth's atmosphere. If we don't act quickly we'll destroy ozone (O3) which is important for the life on Earth because it decreases the effect of the UV. There are already some ozone holes and it's one of the problems of the planet overheating.
