The only problem with that, though, is that it's hard to license. If you needed a license to have children, it would mean you needed it to have sex. Since sex is a basic human need, it would be making such illegal without said license. Which, in turn, goes against the Constitution (for America).
I agree, though, that something should be done to ensure that children are getting the care and love they deserve and require. This kind of thing cannot continue to happen. It's appalling, and almost makes me hate being part of the human race.
