I don't think it works this way. It is more aboit things that stop family formation amd offspring creation from 15 to 35ish, of which earth ruining marratives and the trend in living standards no longer being your friend are part of it. Childhood being extended into mid to late 20's by post secondary is another, overly expensive family housing is another. among many other contributors. If these things succeed in delaying child creation then you end up like me (if you are lucky) and pop out two kids in your late 30's with many miscarriages and discovering the third probably isnt happening with very expensive ivf and even then it is a crapshoot. If you are unlucky you find out you waited too long and indadvertently optedout of the gene pool, at which point the environmental thing is a c(nvenient excuse to use when asked.
