I do not believe that our relationship to the earth is liable to change for the better until it gets catastrophically worse. Our record indicates that we can walk with our eyes wide open straight into sheer destruction if there is a profit on the way-and that seems to me to be what we are doing now. I have no great expectation that human cussedness will somehow be quickly modified and turned into generosity or that humanity's care of the earth will improve much. But I do go around planting trees on the campus.
