It is an interesting argument. I take exception to the suggestion that the earth and animals would be happier if we were gone. Happiness seems to be a purely human concept. Without humans there would be no happiness. It is true that animals would almost certainly be better off without us. But I’m not sure it’s possible to say that the earth would be. The earth doesn’t care one way or another if life thrives. And concepts like justice are only meaningful in the context of intelligent life so it’s hard to argue that justice requires the elimination of the only known life-form that has a concept of justice.
