Plus I strongly disagree with nature being perfect. I know you didn't say that, but everyone else in the comment is. Nature is. It needs no adjectives. Even that which is artificial is still natural, why? Because it happens within the context of Nature. Humans are part of nature. We modify stuff in nature. We use materials that are part of nature. Nothing therefore is artificial. Lets keep rolling until destrcction, which is probably the only certainty of nature.
