- dukeyukey 3y agoAlthough that leads to the mother of all natural selection - after a few generations, you'll have selected almost exclusively for families that have lots of kids. My bet is that fertility will flatten out and recover a good bit over the next few decades.
- LightBug1 3y agoGlobal replacement rate is about 2.3 so ... I wonder when many in those 'rich' countries will learn that they need to embrace that instead of 'build the wall'. Anyway, I don't think replacement fertility is the right measure here. Replacement fertility could be crashing, but if the ratio of 'modern'* humanity is increasing as it is, then the problem remains ... there's probably a term for this if anyone knows. * (by 'modern' [super air-quoted] I mean, those who have the wants and desires and ability to get the goods and services of the 'rich' countries).
