  If you cover 50% of the Earth's land with nuclear powered greenhouses, and the other 50% with skyscrapers, you could house and feed a trillion people. Food is not the limiting factor for population.

      Exactly. It being awful is a reason not to have a trillion people on Earth. Food isn't the limiting factor, other things are.
