From the Washington Post today, we read of a "high-security vault, almost half the length of a football field, [which] will be carved into a mountain on a remote island above the Arctic Circle. If the looming fences, motion detectors and steel airlock doors are not disincentive enough for anyone hoping to breach the facility's concrete interior, the polar bears roaming outside should help."
The project has been endorsed by over 100 nations so far. What's inside? Seeds. Millions of them. Why? The article explains:
The "doomsday vault," as some have come to call it, is to be the ultimate backup in the event of a global catastrophe — the go-to place after an asteroid hit or nuclear or biowarfare holocaust so that, difficult as those times would be, humankind would not have to start again from scratch.
