Yes and no, the way our society is built/structured can't handle negative growth. A lot of infrastructure and way of life/quality of life would suffer massively. That being said, pop growth also can't go up forever (while limited to earth). We actually have a ton of livable land left too, cities have learned how to be so super dense that it's eating all the rural area's populations in quickly developing places (It's where all the jobs and opportunities are -cities). Estimates suggest we will top off around 10 billion people
