And that's why I think they'll be the nail in our coffin.

Humanity can survive climate change; adapting to our environment is one of the reasons we're the dominant life form.

Obviously this isn't saying that climate change is good, but humans have made it through a bottle neck before. But you can't survive a bottle neck if you can't make more people.

Plus, the environment would recover when most of humanity is wiped out. Plastics are here for the next few hundred years at least.

Oh nooo... Not the fertility. We definitely aren't an overpopulated species putting extreme strain on all our environments and the planet as a whole. How can we get by if some, not all, breeders can't fulfill their animalistic urge to have shitty kids?

Too many people anyway
