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?

Light bulbs
Only turn on lights/use lightbulbs in your house when needed, and turn them off as soon as possible/when you leave an empty room. A decreased use of electricity means decreased emissions of CO2 from powerplants. If we all do this, we can collectively reduce our carbon footprint.
I agree. Aside from turning off lights when you're not using them, you should also buy LED lights because they use less energy. Since they use less energy there's less of a need from powerplants. Also, LED lights last longer reducing waste. If more houses and buildings used LED lighting there would be a lot fewer greenhouse gasses in our atmosphere.
