Fair enough, but when you include the world's farmland and consider a more sustainable food system, we could probably support more than you think, especially when you include the oceans and newer technologies, such as integrated urban farming.
However, there might just come a time when we need to expand beyond the stratosphere, so we had better have a plan.
Personally, I'd rather
