Well if Malthusian scientists are to be believed then we only really have another couple of decades at best before the global population level causes society to collapse. So you could interpret recent events to be the first warning signs of that.

Personally I remain unconvinced of that, though. Or at least, it seems to me that humans have the unique benefit of being able to problem solve their way out of the issues related to population growth, at least for a while. We don't have to be gazelles grazing themselves to death or to act merely on selfish instinct.
