We have ruined our earth (face it, we have). Look around, it's ugly; concrete, sprawling, dirty. We have coated our earth in humanness, and I hate it. This wonderful energy of nature, the green trees and bright flowers, is being slowly strangled. Personally, I'd take us back to the stone ages. We could hunt cows and sheep (which wouldn't be hard - the lazy buggers) and have mass demolishing celebrations where we destroy all remnants of our industrial past. Motorways are the worst. They are like big conveyor belts of people; we are just the sausages in the sausage factory.
