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?

The difference between wanting things and needing things
Overall, most people get things because they want them. People get new phones, computers and tv's because they want to keep up with the new technology. The thing is that these are all wanted. You do not need these things because usually, the older thing that you are replacing is perfectly fine and will work fine. When you need something it means that it is necessary to have and you will not be able to do without it. For example, a need is water but a want is a phone.
