Ok sorry guys I forgot about this thread. In my opinion I think the "population control" argument is bullstuff.
In the first place, I don't think abortion happens often enough to have a significant impact on the population. Secondly, the world is capable of handling a few billion more people if we could only handle our resources in a responsible and effective manner. For example, the U.S. government subsidizes farmers to NOT produce all they can in order to keep the price of food up and help the economy. Relieving policies like this (or better yet doing away with them) could allow us to care for a larger population.
As of right now we produce enough food to care for the world's population. I don't think we're overpopulated.
