We're overpopulated. I'm not sure whether or not that's debated, but I think it's pretty obvious.
So, in a world where resources and the future could be severely impacted by how many people are on the planet, why do we still reject ideas of 'population control' such as overseas adoption, abortion, and homosexuality?
1st: China is limiting it's number of US parents adopting by saying you have to be married, in a certain age range, and at a healthy weight. Guess what? That means fewer adoptions in the US. That also means worldwide adoptions

And that basically says 'no' to all homosexuals who want to adopt.
2nd: Abortion is always debated. The fact that China forces a 1-child per family quota has angered many Bible-Belt Americans who believe the world revolves around making as many babies as possible. Although I don't like the idea of enforcement here in the US, in a place like China where at least 1/5th of the world population resides, they really need it. There needs to be some serious care going on here.
3rd: Homosexuality is seen as something bad because it does not follow religion, and does not produce children. Well, honestly, do we *need* anymore children? No. So wouldn't accepting homosexuality more be a better step than saying it's bad?
The encouragement of adoption over vitro-fertilization should be something that doctors do.
Another loosely related topic is that of birth-control. Since an Abstinence-only education doesn't seem to work, shouldn't schools encourage a Birth-Control and Safety in Sex education better? The fact that you need to be 18 to get B.C. on your own suggests something - America doesn't want your kids to take birth control. So when kids decide to have sex (and they will) there will be births. Is it so bad for teens to have sex, especially when they're protected?
