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?

Green gas
It is important to use bio fuel bc regular fuel doesnt fill the needs of modern world and is bad for enviroment, green algae or even euglena are good makers of oxygen and should be making world better.
Wow I did not know that you could use green algae for fuel we should start using that more often for our fuel needs.
Good option, but it would be difficult to convince people, and another point to take in count is the price.
