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?

Light Bulbs
I noticed that my home footprint is the only category that is higher than the average. I believe this is due to the fact that we have mostly incandescent bulbs. Incandescent bulbs are incredibly inefficient and harmful to the environment when compared to something like an LED bulb. Overall my home footprint is 6,803kg per year. How does this compare with someone who has mostly LED bulbs?
