Get a little perspective, too. The problems in Africa are mostly due to warring peoples. Starving each other, etc... Luckily here in America we simply killed all the previous inhabitants fighting for their land on this continent, so we don't have to worry about such problems anymore. We, America, are no different from anyone else. We were just much more effective at our genocide.
Reproduction is meant for just that. And so there is no point in condoms.
It would be nice if issues were so black and white. Unfortunately, reproduction is much more complex. STD's throw a pretty malicious wrench into the works. Condoms are an effective solution (99.9% when used properly) to STD's. However, the church's view is that people are going to start having rampant sex and have a total disregard for the sacred institution of marriage.
If we didn't have marriage we'd never get anything done! Whole cities would grind to a standstill as men donned a condom to plunder pleasure from every pair of legs nearby. Okay, I took that a little too far; but it's funny...
