  See my answer above; before natural selection kicks in and makes the population rebound, we'll already have hit the replacement problem.

    See mine as well. Reduced population is not a problem. Life is easier, not harder, when there is less competition for resources. Our pension systems will collapse, though. People will adapt; pensions have not existed for most of human history.

      From current levels maybe, but not always. We cooperate as well as compete. A world with too few people would have its own struggles.
