If we grow our resource use to such a point that we reach a ceiling, then we are exactly like a pox, or any other organism that breeds until its niche is filled

If we grow our resource use to such a point that we reach a ceiling, then we are exactly like a pox, or any other organism that breeds until its niche is filled. Those who want to make us live sustainably now or previously are hoping that we can be smarter than that. We're supposed to be a smart species. Can we limit ourselves artificially to preserve a better quality of life? Easy to be pessimistic about this now(!)
