I won't elaborate too much as it's a pretty common debate.
Why create children when there are so many children out there that need love and are just as young and viable? If you had a child and it was accidently switched at birth with another child you'd love it and raise it just the same as long as you didn't know. The obsession with having biological children is entirely primordial without any logical basis.
Then again, it is so ingrained in the psyche that I understand people succumbing to it. Also, if a couple has two kids or less they aren't a problem in regards to overpopulation.
What are your thoughts?
