Ah yes capitalism where the female partner needs to work and have no time to be a mom. Then politicians worry about dwindling young labor when it's too late. Also banning porn and censoring sexuality... Shaming sex. Fertility is known to be higher when younger but there's no support to allow the young fertile people to thrive so they work until retirement fate, brilliant capitalism
It IS falling globally. It's also been proven in studies that it will not matter to the current environmental crisis, our consumption habits are what matters.
How does there being less people not matter? If there's more people, there's more people that can consume. It's not the only variable, but it's absolutely relevant.
A billion people will consume more than a million people do.
I haven't seen any studies showing the birth rate is actually falling below previously recorded levels globally. I have seen the rate of births have slowed from an annual significant increase in population to an annual lesser increase in population. Still increasing population, but the rate at which we are increasing has slowed.
