Annalee Newitz has a succinct, bittersweet message for the human race: Mass extinction is coming, and we're probably going to survive it. Whether it's manmade (a nuclear holocaust, anthropogenic climate change),
earth-spawned (mega-volcanoes, a pandemic) or of the cosmic variety
(radiation bombardment or an asteroid impact), there's eventually going
to be catastrophe big enough to snuff out the vast majority of life on
Earth.
