2. Extraterrestrial Doomsday Ark
Seed and gene banks around the world stockpile genetic data, providing backup files on everything from Joe the sperm donor to the extinct Indian Cheetah. That's great news, but, what happens if we lose nearly everything?
Enter the New York University-based Alliance to Rescue Civilization (ARC), which, along with the European Space Agency, really wants to establish a vault on the moon. The members foresee a lone redoubt, buried deep beneath endless lunar wastes. In its depths, they hope to store all human knowledge on hard disk, including DNA sequences, technological information, agricultural instructions and, yes, maybe even a copy of "2012." The more ambitious stages of the plan call for a sealed Earth-like habitat in the lunar vault and even a staff of human employees -- eventually a human colony.
You may be wondering what good a lunar vault of complete human knowledge would do for a scrappy band of post-apocalyptic wanderers on a forsaken Earth. Well, ARC plans for them to tune into radio transmissions from the moon, perhaps from one of 4,000 heavily fortified radio receiver stations on Earth. Each of these stations would remain constantly tuned in to the apocalypse's only radio station for instructions on rebuilding society.
ARC hopes to install the first stage of the project by 2020.
