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?

Surprised
I had no idea that we had over 100 lightbulbs in our house. Seriously, who needs over 100 lightbulbs. Although my footprint was lower than our state average, I think it underestimated what my family's footprint might be. Our house is far from my parent's jobs and, although we have fuel-efficient cars, that is a factor that was not included in my calculation.
