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?

greenhouse gases
Greenhouse gases trap heat which makes our earth warmer. Many people are adding more greenhouse gases. Each gas has an effect on climate change. The gases travel around and mix . if we keep on heating up the world we can have many problems. for example the ice can melt and animals like polar bears depend and live mostly on ice and if the temperature keeps on rising then there is a possibility the ice will melt and they will go extinct.
