Q:
A: The planet will go on. As for the life living on Her, that depends on how long our species can survive and what we do while we're here. A lot of cleanup is already going on, but there is a great deal more to be done, every day. We don't have a simple on/off switch for this, and many life forms could survive long after the earth can no longer support humans and other large animals. If we didn't do anything at all to clean up as a species, the 75 year mark for human life plummeting is as good as any, and it would get pretty ugly for most of it.
