Lots of natural processes are bad for humans. Evolution, extinctions, forest fires, floods, droughts, hurricanes, earthquakes, erosion, etc. All of these things happened before humans, and we still would sometimes like to stop them so that there is no "after humans". We don't need to save the planet, the planet will be fine, we need to save ourselves.
