Good point, aC23.
If its overpopulated where you live... then move. I know of whole areas here in the U.S. alone where there is not a single soul around. Overpopulation is a myth in my opinion that is only believed by people living in big cities. If fact, there are whole states that have less population than New York City. I heard a report once that said that you could fit the entire population of the earth in the state of oregon (though not confortably). So if your feeling crushed in, go find a desolate place to live in... there are plenty of 'em!
Overpopulation has nothing to do with land. There are hundreds of thousands of square miles of uninhabited hinterlands all over the earth, but that is not what overpopulation refers to. Overpopulation is when there are too many people to be able to provide them all with decent, human, healthy standards of living. Sure if there were 15 billion people on the earth many of us would survive, but it wouldn't be too much fun. We would be living a miserable existence. Overpopulation has more to do with the environment being destroyed and becoming incapable of supporting human life, something that is happening rapidly. It also has to do with providing adequate living conditions and providing people with food and medical care. We can't even provide AMERICANS with adequate living conditions and food and medical care, forget about the rest of the world!
As for reconciling religious beliefs and population control. I support human life and think that it is holy and beautiful, but I support population control. I don't support population control of people of Western Civilizations because there has been a form of population control imposed on them for hundreds of years that should be reversed for the world to continue progressing. Population control can also be supported on humanitarian grounds. I want the people of Africa and India to live comfortable lives and not have to starve to death. By fueling their population growth through food and medical aid to third world countries, we are prolonging and exacerbating their suffering. The only way they'll be able to live comfortable lives and support themselves materially and spiritually is if they decrease their populations to managable levels and learn to support themselves. We can't do that for them, they must do it on their own.
Population control can be supported based on religious and humanitarian grounds because it ultimately benefits the people who will be living in improved conditions and it upholds their right to live decent and honorable lives. If we remain objected to population control, Africans and other people will be subjected to misery forever.
That's inhumane if you ask me.
