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
Plastic is an item we use everyday, but do we really need so much of it?
It is very cheap and good to use in many things, we can't completely eliminate it, but we can change what makes up it. Plastic is made from chemicals that mainly contain carbon, so if the chemicals were something biodegradable it would mean the plastic is less harmful to the environment. The sub could be corn, potatoes, or other plant-based chemical. This will reduce a large amount of soft floatie carbon and we can continue to use plastic.
