The fact that I don’t speak any other languages doesn’t imply that I’m only referring to English speakers. That’s a ridiculous argument.
And I don’t advocate that people stop procreating. I don’t actually advocate anything, but I don’t personally think it would be a net harm if the entire population of the world chose to have less children for a generation or two.
No, I live in a pretty small place. My point is that we could probably find all kinds of ways to cram way more people on the planet. But would we want to? Is that really the world anyone wants to live in?
