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?

Green Travel
I feel that through these past few years many engineers are starting to get serious about eco-friendly energy in transportation. Some people think that solar energy is the best for aircraft, but I think we need to use a combination of biofuel and solar panels. The biofuel would be solely propulsion, where as the solar panels will simple provide energy to batteries powering the mechanisms onboard.
