Oh yeah---tell that to the nutria and fire ant (and thousands of other species whose range has been greatly expanded by human activity.
Climate changes, species go extinct---so what. It has happened since the planet cooled enough to have liquid water.
Change is the reality of the world--you "global warming" propagandists are trying to achieve stasis--which is flatly impossible.
If I had a goal, it would be to limit, as much as possible, the loss of habitat and species tied to human activities. That's a vague and unquantified statement, but it acknowledges that stasis is impossible. However, some planning can mitigate avoidable losses.
