Biso,
I think the population is headed towards something that will bring it under control, because that is the way evolution works, it will be brought under control, or it may just become extinct, I don't know the future. Everything that happen happens for a reason, which are too numerous to understand.
But perhaps I could suggest this:
That since man "evolved" with a brain that has gained the ability to read dna ,,,and,,, restructure it,,, that this brain may also give us insight as to the best way to preserve our spiecies,, and perhaps cause us to voluntarily do things that make life much more comfortable which may include puting strict limits on the population.
I don't know if this would ever happen but I would not be surprised if it did.
