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?

Electric cars and their rise in popularity
As car companies like Tesla, Nissan, Chevy, and BMW create electric cars, I see them more and more making appearances on freeways which is a great advance in reducing our carbon dioxide output. These cars have a much smaller impact on our environment than the classic fuel burning vehicles most of the world drives. However, these cars are very expensive than the regular gasoline car so it becomes much harder for people to afford. But, it is a large, must needed step in the right direction for our planet.
