35 or 40 years ago, the Catholic Church was subject to a lot of criticism for its stands against any form of birth control. Many Catholic third world countries were seeing an expansion of their population, and the resulting furthering of poverty, while the Catholic Church made it a sin to practice birth control. I always found (and still do find) that to be incredibly irresponsible. But again, I don’t hear much about that anymore.
I just think that it’s time we revisit the idea of controlling the population a bit better than we do now. I’m not sure how we lost focus on it in the first place, but it’s time we rediscover an “old” problem.
