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?

A PPM reading in the Bay Area of California
Recently I did a study on the PPM of certain places on BOD campus. We went to the living lab, a small place surrounded by trees. This place is in the urban part of Oakland. We got a reading of 383PPM. Then We went to another part on campus. Near the has pipes of school, around this area are many cars and a kitchen where the food is cooked. This place is also in the heart of urban Oakland. The PPM for this place was 350. We had thought that since one place was covered with trees and a small pond and one place had gas pipes, a kitchen, and cars that that one would be higher than the first. Does anyone know why this problem occurred, or was this human error?
