Ineffective..for now. But, with how we're preventing man from adapting to all diseases with vaccinations and other "cures", there will be one eventually that we cannot hide from... we as a species are very vulnerable thanks to our reliance on our "advancements" and invetions. I hope that global warming and the predicted increase of natural disasters will take that role. It's random, at least. I just hope that we can learn to control our population before we sacrifice everything. Earthquakes, for instance, you'd think they'd only damage the human population seeing that we've put ourselves in death traps (houses). I don't really know what i'm saying anymore
Has anybody watched that show "Life After Humans" on the history channel? It's very reassuring to know that the earth will repair itself, however slowly, as soon as we're gone lol.... although I find the show rather phony, I'd like to believe it anyways.
