Do you know about exponential growth? If birth and death rates are not about the same, it means the population will double every X years. You’ll need a major breakthrough in food production every X years. For ever. Even if we achieve that, at some point there just won’t be enough square meters on earth. But I guess it’s okay to you since we’ll have solved space travel and we’ll just send billions of people to Mars? Then other planetary systems? Then other galaxies? In any case, as I don’t buy we’ll ever be able to send billions of people to other planets, let alone make them habitable, this is exponential growth with finite ressources. Doesn’t sound sustainable to me.
