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?

Cell Phones
Cell phones are everywhere now, they are a great safety tool for emergencies. Unfortunately, our battery runs low all the time with all these wonderful apps that are helpful or entertaining. When it comes to an emergency our phones may not have enough charge on it when we need to make a call for it.
Unplugging is a great way to save battery percentage
