Are our day’s numbered? Here is a thought-provoking video. Last Days of Man is a scientific examination of the top ten disasters that have the capacity to annihilate the human race — and it’s not just the usual threats from nuclear weapons, climate change, and meteorite impacts. There are a number of lesser known but much more probable risks to humankind–threats that humanity has created for itself. Borrow Last Days of Man (I.D. 2433) for a month by clicking here.
