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?

Energy Saver
Energy costs at home can be very high if people do not watch how they are using it. A bathroom light left on might not cross your mind for long, but think of all the energy and even money you could be saving if you remember to turn it off. Or the amount of water that can be saved if the faucet isn't steady dripping.
There are lot of handy gadgets and apps nowadays to help keep track and control all this wasteful energy usage. I thought this one in particular was interesting and could be quite useful.
