I like the idea that somehow the quality of the world is somehow intrinsically better when humans aren't involved. Certainly there are plenty of ways that humans can make it worse, but that is not the same thing as saying that somehow humans are less a part of nature than any other organism or geological feature.
I wonder if the narrative that humans are not of nature makes it easier for us to harm the environment, since we do not feel part of it (as evidenced by our use of the word nature as some _other_).
To the contrary, there is a worldview whereby humans are not part of nature. Instead, they have dominion over it and a responsibility to care for all aspects of it as a custodian. To use a metaphor, nature without humans can never reach its full potential, just as a garden without its gardener will revert to a less ordered -- and less diverse -- state.
I believe the hypothesis that we're not one of these animal species may well prove false.

Neither do humans. We tend to fuck things up until they become real problems, then mitigate the damage, sometimes with success. That's not really conscientious, that's "winging it". This is the true nature of the human being.
