I just hate when people refer to that specific part of his standup as anti-environmentalist. I think he didn't meant it like people are quoting him to approve destroying nature. The planet will be fine (c), sure, this stone rock will be fine. Humans won't be, animals won't be, plants won't be. We probably won't be able to exterminate all living things on Earth, and some plankton and bacteria will evolve into something new again. But again, current snapshot of "nature", the one we are all living in will be lost if it continued to be destroyed.
