I mean, there are only two ways this can go: 1. Humanity's population decreases (voluntarily or otherwise) 2. We figure out how to get humans off of this one specific oblate spheroid we call "Earth" Personally, I'd much rather see Option #2 happen, but given how unwilling we seem to be as a species to pursue that branch, #1 seems to be inevitable.
