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?

Why to save our planet’s environment
Our Planet – The Earth is about 4.5 to 4.6 billion years old and is the only known planet to support life. Earth is the third planet from the Sun and is the largest of the terrestrial planets. The Earth is the only planet which is not named after a Greek or Roman deity like other planet names in our solar system. Earth is the only planet on which water can exist in liquid form on the surface and however liquid water is of course essential for life on earth. Also the heat capacity of the oceans is also aiding the Earth’s temperature to be relatively stable
