If we were up there among the planets, if there were self-sufficient human communities on many worlds, our species would be insulated from catastrophe… A cataclysmic impact on one world would likely leave all the others untouched. The more of us beyond the Earth, the greater the diversity of worlds we inhabit… then the safer the human species will be.I like Sagan, but looking to one sort of loopy visionary astronomer for policy direction might not be very productive.
