That links helps a bit; it suggests that you mean that nature would be better off without humans, which is along the lines of what I was thinking.

If you unpack what most people mean by good for the environment, they mean how the environment would be if humans weren't around, or more particularly, if humans never developed reason.

Both of the bullet points in the wiki summary for Natural Environment explicity exclude effects of human activity - "without massive human intervention" and "not originating from human activity."
