There is a failure of fertile-age couples to get pregnant.
Could be contraception, but a lot of it is due to perverse sex (hetero or homo), and I'm reading that a surprising number of fertile-age men and women have to some extent given up on actual interpersonal sex altogether, and instead are doing sexting and porn.
It's extreme in Japan, which is in the midst of slo-mo demographic collapse, but it's happening here as well.
Japan will survive as a people and culture as long as they dont start importing culturally backwards savages like europe is doing.
Their population my dip down, but it will stabilize.
Europe is commiting cultural suicide for sure.
