With millions of starving and dying children - in abject suffering and without love EVERY single day of their lives - how can people conscionably create more children?
Because that is how evolution works and we aren't yet smart enough to avoid a population crash from having out stripped all our predators.
You see we are pretty much weak and defenseless. Your average chimp could rip your favorite hulking steroid popping wrestler to pieces. We've no claws or fangs, we are slow and our senses suck. So before brains and technology kicked in we had very few means of dealing with being low on the food chain was to breed like crazy.
I can't think of another species other than bonobos (our closest relatives) whose females are fertile throughout the year. That's really hard on the body and the group's social cohesion since it keeps the males going at each other all the time.
We also eat almost anything. We've an absurdly huge range of food stuffs.
And we are willing to move around and seek new territories.
And we can form symbiotic bonds with a huge array of other animals.
So... we lack the genetic ability to keep from over populating and dying back without our predators. So there is going to be a lot of people dying and a lot of people having kids until we either can handle it with our brains, our genes or we die out.
Since we are the predominant large animal in all land ecosystems, dying out is not likely, but we can sure do a lot of dying back.
The last time things looked like this was the die off at the beginning of the Triassic.
