And I do believe that we are in fact headed towards such a die-off. Perhaps not in our lifetimes, but I see it as inevitable without some crucial technological and economical developments.
Really though, I don't think we should worry about natural selection and evolution. We're human beings. We write our own rules.
Actually because we have basically dominated this planet the chances of natural selection ever having an impact on us is very slim, so we are actually much weaker then we could be, all though we are much smarter so its kind of a catch 22.
I guess for us, natural selection will be something like if we vaccinate each other so much we create a mega virus that wipes out the majority of human life.... This is possible.
But as for traditional natural selection such as hairy greek humans will survive in cold climates and hairless asians dieing, or tall humans picking the apples from trees and short ones dieing of starvation... Yeah you are right, we write own own rules here, I think it will be our rules that lead to our selection...
