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?

Technology is a want and a need.
Having the latest technology is a want and a need but it varies for different people. Technology is a want for most people because it is used for things that are wastes of money like refrigerators have technology with cameras. But without prosthetics and computers some people wouldn't be able to live. Technology is the #1 method of saving lives. Without technology we wouldn't even know how to make medicine because all the data is stored online.
