Did you see David Attenborough on TV last week? According to him overpopulation is what we should be solely concerned with. Nature naturally balanced population to about 1bn worldwide until the intervention of science prevented deaths. Over the past century the worlds population has exploded to 7bn projected to reach 9bn by 2050. Religion, although contributory, has not had much impact.

The Catholic position on condoms is that it promotes promiscuity to send a message that having promiscuous sex is fine. Convincing people not to be promiscuous would be more beneficial in the reduction of the spread of AIDS.
I'm not suggesting that you need God to think positively. I just think it ironic that you hold this against God like this physical reality is far from ideal. If you're positive for this reality, then in my book that's the same assaying you're happy with it should it have been created by God. IOW stop the bellyaching.
