"The planet has been through a lot worse than us, been through all kinds of things worse than us, been through earthquakes, volcanoes, plate tectonics, continental drift, solar flares, sunspots, magnetic storms, the magnetic reversal of the poles, hundreds of thousands of years of bombardment by comets and asteroids and meteors, worldwide floods, tidal waves, worldwide fires, erosion, cosmic rays, recurring ice ages, and we think some plastic bags and some aluminum cans are going to make a difference?
