There are too many people on the planet already, and most of them don't have a good quality of life. And more importantly, there isn't a way of significantly improving it (with today's technology and social/ethics understanding)
I feel the reaction many people have about population decline in NA and EU is understandable (one may or may not share the concern though, that's personal): your tribe is making less children, the others do no seem to care. And they will replace your tribe in the future if you don't make children, it's a game of numbers in the end.
NA and EU count very little in the great scheme of things from a population perspective [1] anyway - there are 5+ billion people in Asia and Africa (many in places that will be devastated by global warming), and those people aren't going to stop making babies any time soon. Are we going to force them to stop? How?

Actually, in Asia they are mostly stopping https://ourworldindata.org/fertility-rate India is 2.5ish already, China is below 2
Yes, there is reason to worry about decline and population replacement, at the same time, numbers are not all there is (especially when people are unhappy).
