Although in this day and age there still the threat of nuclear war. Theres another emerging probability biological warfare. In the past ten years there have been massive improvments in the biological field. They've cloned animals, found cures and altered many virusesfor different uses. Thats not to say what if someone could enginer a virus that kills within a few days and is airborne. Just saying in a world of nuclear threats this one gets over looked. Just saying this could be another way that humanity could destroy itself. Millions of evolution all so nature could make a species that could cause its own extinction. Theres a movie coming out about this scenario.
