We are merely somewhat intelligent animals whose biological needs to reproduce overwhelm our limited intelligence.If you were to survey a lot of people, and if people were answering honestly, very nearly all of them would have to admit that they wouldn't be alive today if it weren't for modern medicine.
If I had survived until my teenage years, strep infections would've had me. If I'd survived those, pre-eclampsia in my pregnancies would've had me at 24, or 27, or 30. Since 30, there have been a number of other things.
If anyone has had any kind of serious illness/infection, or injury, or birth defect, or any other medical misfortune, well, just visualize that.
Many people thought how barbaric the Chinese government's regulation of family size has been over the past many years, but certainly having a policy is less barbaric than engaging in war. It's also less barbaric than bringing children into the world anyway, and leaving the baby girls in the woods to die.
Sounds to me like we created, or at least exacerbated, a problem in an attempt to be humane and empathetic, and cannot solve it without being barbaric in one way or another, or several. What a position to find ourselves in! We're painted into a morality corner!
And the vast majority of humans believe themselves to be the most intelligent beings in the universe
