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?

To recycle things
In the past year in the country, I noticed that people (including myself)usually only use materials and things as paper and plastic bag for once. People usually don't care about recycling simple things so they throw them to the garbage. I personally think something like use paper twice should be a habit.
You are right! People should use and reuse things more than they do now. For example, I have a friend who every day changes his plastic bottle. Where I live we are lucky that tap water is drinkable, then why don't people fill their old water bottle with new fresh water every day? Going from a plastic to a metal bottle would be the best thing to do because you don't polute, but going from one plastic bottle a day, to maybe one a week by filling it with tap water, is already an improvement.
