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?

Insulating Your House is Better For the Environment
Using effective insulation in your home can have a great effect on the environment.
When insulation is not effective, the home takes longer to cool down in the summer and heat up in the winter. This causes the air conditioning unit to work longer, which is bad for the environment.
With insulation that works properly, however, the energy used decreases drastically, which is way better for the environment.
