There’s a lot of empty space everywhere. Entire continents are mostly empty. You may have a preference to leave those continents uninhabited, but if humans need the space they’ll use it. It will be a lot easier to colonize the Australian Outback and Antarctica than Mars.
- defrost 3y agoBetter yet, learn to live within our means and leave these spaces as they are. To the question asked, 4 -6 billion seems a better range than > 8 billion as our current numbers and expected near future demands are straining resource and energy supplies, piling on waste and taking down non human planet cohabitors.
- sillywalk 3y ago"Entire continents are mostly empty." For many reasons. Big one: water. Or lack of. Or too much. Also food.
- bryanlarsen 3y agoFood and water are not significant obstacles for a rich society. Desalination would increase the price of water from 0.2% of GDP to 2%. Greenhouses produce 1000x as many calories per acre for 10x the price per calorie. (And a 10x of ingredient prices would only double the final cost)
