It's not a problem. Go look at a graph of historical world population: https://en.wikipedia.org/wiki/World_population#/media/File%3...

It's virtually flat for eons, and then in the last 100 years it shoots up like a rocket. We didn't hit the first billion people until 1800, but the 8th billion took only 11 years. (2011-2022)

This rate of exponential growth was never sustainable, and it's normal and natural that it's leveling off now.
