Ideal population of humans: How many people can, or should, each country, and the whole planet support?
It seems like the human population has forever been growing, but any analysis makes it clear growth must stop eventually at some level. The question becomes at what level should growth stop?
Do we go for the maximum possible people just before everything collapses, even if average living standards could be far better with a smaller population? With caged hens being farmed for eggs people advocate for a lower free-range population instead of denser living caged hens as it provides a better existence, but does anyone advocate against multinationals and politicians pushing for denser and denser housing for humans in order to allow bigger populations of humans for them to farm?
It seems to be accepted that global population growth should stop but claimed that countries who end population growth face economic disaster.
