Doing everything we can, including birth limitations and laws, to not get there.
I recently heard about China stopping the one-child law stuff and I only wanted to facepalm. That's so typical. "We need more population for all our old people here!" disregarding what will happen with the planet (an objectively much more important thing than China, but hey, it's not China, so not their problem, right?!), if population surges again in China. I just hope, that the experts are correct and that it will not lead to another population increase.
