The apocalypse could strike the world any time, given the violent forces at work everywhere. But man can still survive such a holocaust, Norway says.
For it will soon start storing all the available crop seeds across the world n a cavern under a remote Arctic mountain.
Dynamited out of a mountainside on Spitsbergen island around 1,000 km (600 miles) from the North Pole, the store has been called a doomsday vault or a Noah's Ark of the plant kingdom.
It is the brainchild of a soft-spoken academic from Tennessee who is passionate about securing food for the masses, and will back up seed stores around the world that are vulnerable to loss through war or disaster.
A 20-metre (66-foot) long concrete entrance, still under scaffolding, juts out of the snow-dusted mountain above the coal-mining town of Longyearbyen.
It is reached by a switchback road rising to 120 meters above sea level, offering spectacular views of the fjord below and snow-capped Arctic mountains beyond.
Visitors descend through the mouth of a gently sloping 40-metre steel tube into the frosty cavern which smells of new cement and is dotted with portable lamps as work progresses for February's opening.
"There aren't going to be any better storage conditions than what we will provide here," founder Cary Fowler told reporters during a recent visit to the site in the Svalbard archipelago off northern Norway. "This is a safety deposit box, like in a bank, where you put your valuables."
