In a way, human beings have never been part of the natural order; we’re not biological in the normal sense. Normal biological animals stop eating when they’re not hungry and stop breeding when there is no sense in breeding. By contrast, human beings are what I think of as “biomythic” animals: we’re controlled largely by the stories we tell. When we get the story wrong, we get out of harmony with the rest of the natural order. For a long time, our unnatural beahvior didn’t threaten the natural world, but now it does.
