After watching this video I am left with this question.
The video ultimately claims that humans will not disappear, but doesn’t do a great job explaining why.
Correct me if I’m wrong, but for the (or a) population to be and remain stable, the total fertility rate needs to be equal to the global replacement rate (which recently was 2.3).
And since the total average fertility rate appears to be currently at this 2.3, any drop in the fertility rate in place A would have to be compensated with a rise in the fertility rate in place B (assuming that, at some point, we would like to stop population decline)?
I guess one way for a population to remain stable, while women are having fewer than 2.3 children, would be to have fewer men? If a population has 100 women and 10 men, each woman would only have to have on average (a bit more than) 1.1 child? (Which would of course also require a collective form of prenatal sex selection.)
I realize that would be bonkers and unethical. Just wondering out loud.
Yea I completely agree with everything you said. Life in rich countries doesn’t mean that everyone is rich and lazy and fat. I mean just look at the US. So many people live in poverty and literally cannot afford kids.
Well I’m glad it made sense since I put my phone down and accidentally posted while I was still drafting it lol
I’m going to make a few edits to complete my train of thought.
