Svalbard Global Seed Vault is the world’s largest seed bank on the Norwegian island of Spitsbergen about 1,300 kilometres (810 mi) from the North Pole. The storage rooms are kept at −18 °C (−0.4 °F) as the low temperature and limited access to oxygen will delay seed aging by lowering metabolic activity.
The mission of the Svalbard Global Seed Vault is to provide a safety net against accidental loss of diversity in traditional genebanks. This seedbank will be accessed in the event of a major regional or global catastrophe. For example, the national seed bank of the Philippines was damaged by flooding and later destroyed by a fire; the seed banks of Afghanistan and Iraq have been lost completely because of war [source: Wikipedia].
