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?

Does garbage recycling important?
Now in the modern world the increasing popularity acquires recycling raw materials. In many countries on the streets are installed containers for separate waste collection: paper, plastic, glass. Build plants for the processing of secondary raw materials.
We are faced with the question: how it can help all of oruzhayuscheny environment.
First of all, recycling paper helps us to save the forests of our planet. One hundred kilograms of waste paper can save one tree. A tree is our first helpers in the fight against carbon dioxide as they absorb it and release oxygen, neolbhodimy us for life.
Then we can discuss the processing of plastic. Throwing plastic bottles, we greatly pollute the ground. Just imagine, one plastic bottle can be expanded about a hundred years! So why not take the start in the plastic processing, to replace plastic bags with paper or fabric ?!
Thus, I can say that the processing of waste is not the last place in the environmental protection sreedy.
