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?

Hydro-Houses
Seattle should start building houses over the water, that generate their own electricity from the currents and tides. This way Seattle can expand as it needs to, without stacking apartments in one place, or expanding outwards on land- creating more space for trees so they can help slow the carbon emissions. Hydro-Houses could also use solar panels for energy. The only problem is the expense.
Oh Yeah!
Good Idea Dichali! This is a great idea that should definitely be used in our cities and communities.
That's a good idea, but what implications does that have on marine life living in habitats above the hydro houses? Is that worth it?
