One of the beautiful things about planet Earth is that it does not care whether we live or die. It is independent. It has its own thing going on. We are tiny, tiny mites on the surface of the Earth. And some day, if we’re careful, if we care, we will learn how to live on the Earth without wrecking it. You see: it doesn’t care if we wreck it, but we should, because it is we who find it beautiful. Some day whole nations will move across the Earth and leave every place just the way they found it, not a blade of grass bent over. And they will do this not because the Earth wants them to, but because they want to.
