I hear you, but for sperm counts to go down 50% from the 1940s. I don’t know what that’s about. It definitely needs more study. Of course, feminism has a lot to do with it.
As others have said, this won't be the end of humanity. But the western Roman Empire underwent a similar population collapse, with survivors huddled in cities with 5-10% of their peak population as things went to ruin around them before the barbarians swept in virtually unopposed. It was the end of civilization.
My sperm count goes down automatically when my eyes see nose rings, stretched-out ear lobes, multiple unartistic tattoos and hair of various unnatural colors - usually in combinations with each other.
Oh...and when mindless TDS tirades come out of their mouths. That alone negates physical beauty that God bestowed upon them.
