Well we did more presentations today. There are several sources of alternative energies like solar, wind, geothermal, and hydro. WE are still working on ways to make these sources produce sufficient amounts electricity. Polar bears are one of the first animal to be endangered by global warming. The endangered species act protects endangered animals and help revive them. Polar bear numbers have gone down lots because of human hunting and global warming. That was as far as we got because bruns had to leave for a tennis meet or something so we had the rest of the day as a work day.
