The population will expand at a rate supported by available resources... as the population grows, the individual's share of resources reduces and fertility and/or survival rates will drop.
It's never been a case of "oops, too many people, we all die today", it's a case of "everyone gets more and more miserable but enough people die that some will live".
That's how Nature keeps populations in check... she's not a nice lady.
