GR:  Nowhere is safe for rhinos. Once intelligence arose alone without the guidance of wisdom, most of Earth’s species were doomed. Can our species survive when only the toughest ruderals remain? Perhaps we will die or send a small colony into space. Either way, evolution could once again begin to recreate the biological riches it held when we appeared. Probably not. Why go to space when we can cover Earth with solar cells, wind turbines, hydro-generators, and of course, hydroponic greenhouses. With only small adjustments, our current non-sapient behavioral systems will survive.
