"Evolution can go to hell as far as I am concerned. What a mistake we are. We have mortally wounded this sweet life-supporting planet—the only one in the Milky Way—with a century of transportation whoopee. Our government is conducting a war against drugs, is it? Let them go after petroleum. Talk about a destructive high! You put some of this stuff in your car and you can go a hundred miles an hour, run over the neighbor's dog, and tear the atmosphere to smithereens. Hey, as long as we are stuck in being homo sapiens, why mess around? Let's wreck the whole joint. Anybody got an atomic bomb?"
