A new rationale for returning to the Moon? Protecting civilization with a sanctuary

A process is well underway in which the scientific, technical and cultural information vital to our society is stored in digital form within a limited number of computer facilities. This practice is vulnerable to a variety of catastrophes which would destroy our knowledge base in addition to the losses they caused to population and structures. The Alliance to Rescue Civilization (ARC) proposes that a staffed data backup facility be constructed in a secure location, with the Moon as the site of choice. If Earth's population were destroyed entirely, the lunar sanctuary could serve to repopulate the planet.
