Well, Guest Steve, I think you've hit the nail on the head. If we look at what is best for the planet, we would be interested in decreasing the size of the "human footprint," I would think. The best way to do that would be to intervene in human migration around the globe, so we are not encouraging people to move from hopelessly overpopulated areas to places that are not-quite-yet overpopulated. And work on saving wilderness, oceans, wild and sea life, organic farming and etc.
