I saw a show about mouse infestation...they ran out of food and ate each other. I could see humans doing that.
If it was just homosexuality on the rise, that'd be nice.
What was that like having so many siblings? Did you ever feel like your parents didn't have time for you or like you were being raised by your siblings? That's my big problem with large families is siblings raising siblings. That's not fair to the older or the younger children. Of course, I only had one sibling and I had to raise her. Considering how bad she turned out, I didn't do a very good job of it either.
Given the same total number of offspring... I think it's healthier to have fewer larger families, than millions of one-child families. Larger families are learning experiences and built-in socialisation programs. They are good for the parents, getting built-in baby sitters, and good for the children, who grow up with at least some basic parenting skills. That was China's great mistake, to force everyone to one child, making THAT child ever so precious and sending abortion and infanticide of baby girls through the roof.
Unless I get my dream that humans stop breeding altogether, which isn't going to happen, we need a lottery system (to be fair and unbiased), where some get to have a decent sized litter (to emulate Dogly) and live the extended family lifestyle, and other members of society remain childfree and work or research or volunteer or do politics or whatever others tasks required of modern society which generally creates absentee parents.
Single children are more spoiled, uncaring, selfish, egotistical than among a group of siblings.
I just wrote a blog entry including some more thoughts about the difference between breeders' and non-breeders' perception of what is self-interest.
I am not defending breeding as anything of value. I am only attempting to explain the breeders' instinctive urge to breed to restore homeostasis as something real for them. I accept that their urge to breed is as real as is my repulsion and repugnance of breeding. It is my attempt not to project my own inclination on others.
Some people's urge to eat and get fat and survive the next famine, that for them never comes, is very real. That does not give value to obesity. Instinctive urges are an obsolete but real part of the animal part of the human brain.
