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?

Reuse and recycle
Americans throw away over 35 billion plastic bottles a year. Using reusable water bottles can save the environment because less plastic water bottles will pollute the earth. If the majority of people started using reusable water bottles, then some plastic water bottle companies would not need to make as many bottles because of the factor of demand. The demand will decline because less people would need plastic bottles. If more people used reusable water bottles, then number of wasted plastic bottles would decline.
