Global population is not going down, is stabilizing, but we are too many already.

The issue is that we, as animals, have had unnatural survival behaviour, so the world population grew exponentially from 4 billion in 1974 to 7.5 billion in 2018, almost a duplicated number:

So yes, it is an issue, though. If any other animal had this kind of behaviour, humans will, for sure implement a reproduction control in order to stop the (hypothetical) animal to become a plague.
So, in fact, and given the reproduction behaviour, humankind can be considered as one.
Yes, education can be absolutely something of value in stopping this incredible and crazy increment. But the humans have already altered the earth so much that is starting to be considered at this particular time as a new geological era: Anthropocene.
