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?

Plastic Bags
The problem of plastic bags is urgent nowadays. Recently, I began to notice that my city also faced with this one. I did a little search on this. I found that people use plastic bags because of the money issue. In most of the markets there are free plastic bags for packing your products. I know that plastic bags are much cheaper than, for example, paper bags. But if we think about our environment, this small amount of money doesn’t matter. I know that most countries have environmentally friendly packages available. But I haven’t seen a market in my town that sells such bags.
