A strategic reserve is the reserve of a commodity or items that is held back from normal use by governments, organisations, or businesses in pursuance of a particular strategy or to cope with unexpected events.[1]
A document issued by the US Department of Defense in 2005 defines a strategic reserve as follows: "An external reinforcing force which is not committed in advance to a specific Major Subordinate Command, but which can be deployed to any region for a mission decided at the time by the Major NATO Commander."[2]
There are several national and international projects aiming to preserve the existing natural wealth and diversity in case of mass extinction or a global catastrophe. The Svalbard Global Seed Vault facility, opened in 2008, focuses on collecting duplicate samples of plant seeds from all around the world and currently contains close to 1 million different agricultural seed samples. The final storage capacity is said to be 4.5 million seed samples.[3][4] Another such institution, Frozen Ark, concentrates on DNA preservation of endangered animal species for generations.[3][5]
