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
When we run out of water for example, we should refill it instead of buying a new bottle. We also have to reuse paper that we barley use instead of throwing it away. Zip lock bags are another example, we can easily make another sandwich and put it back into the same bag so we don't have to keep getting more of it.
