An anonymous reader writes to mention a New York Times article entitled Life After Earth. The article looks at 'bio-vaults,' be they in the frozen north or on the moon, which might allow the human race to continue on after a globally catastrophic event. From the article: "The trouble with doomsday, Dr. Shapiro argues, is that it is almost always rendered in popular culture as grandiose, though in reality, many minor incidents present substantial everyday threats. In 1918, an influenza strain killed some 30 million people; a possible new bird flu strain spurs contemporary panic. In January 2003, a computer virus shut down airlines, banks and governments. That same year, a tree fell on power lines outside Cleveland, resulting in a blackout for much of the Northeast. Doomsday can be understated."
