Is it normal to think we should adopt before starting new life?
There are so many kids who desperately need homes and love and security, and yet still so very many of us feel a "need" to reproduce. It's not as if our species were endangered, either. And our population growth, even with advances in sustainability, is among the greatest threats to the ecosystem--including us humans ourselves.
And there are people who'll have four, five, six, seven... kids. I won't ask "why?" because I know it's complex, even visceral. But, really. It's time to start controlling human reproduction, 'cause it's too easy and too frequent. And all the while kids are abandoned because no one happens to want them.
