Population growth can go too far, can’t it?

Last I checked the world seems to be ending around us one day at a time as we march towards an ever higher global temperature, but if you want to say that’s normal and fine and we’re gonna be ok in 250 years then overpollution from overconsumption isn’t a problem yet.

At what point does the earth become overpopulated? are we already there? if not… what’s the magic number?
