Short Term Memory

If there was a poll of 100 people that asked the question: Which is more dangerous? Nuclear Weapons or the prevailing sentiment that every single human life is sacred. I don't think the results would be surprising. I have no idea which actually is more dangerous, but I at least think that it is a much closer race than most.

I think it is generally accepted that weapons are more dangerous simply because they are immediate. They are active. Whereas, the danger that comes from the belief that life is sacred is much more subtle. It is passive. It takes much longer to feel the effects. It is also more ambiguous as to its result. But I do think that overpopulation is just as much a threat as massively destructive weapons. And more insidious, seeing as how you can't exactly march with placards that say "Let some human beings die!" as easily as you can with one that says "Choose life, stop the bombs."

I like attempting to deny my baser instincts and think about things long-term. It is much too easy to think only about the short-term. It just makes me wonder.
At what point does the quality of life of the human species outweigh the survival of a human individual?
