I think you might be looking at my comment in too much of a binary way. You also shouldn't build houses in places that regularly flood either. We have more than enough land in hospitable places with abundant water, and no consistent flooding or other major disasters. Our shortsightedness alone probably leads to more than enough waste to house and feed the entirety of the planet. Moving huge amounts of people is of course a logistical nightmare, but it would have been much easier a few hundred years ago. Anyway, none of this is realistic because we're humans. Our foolishness is an inherent trait. If we can survive ourselves, it'll be out of pure luck.
