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?

Turn off the lights
Using less energy is essential to green living, and the easiest energy savings come from the energy you never use. Electric lights left on needlessly waste energy. A simple way to reduce your energy use is by just turning off the lights when you are leaving a room for more than a few minutes. Also, think about whether you need the lights on in the first place. I realized that by opening the blinds in my office I can work perfectly well with the lights off. Turning off the lights is easy and saves you money on electricity and light bulbs, regardless of what type of bulb you are using.
