awed by the biodiversity secured in the seed vault.
B The seeds in the Svalbard Seed Vault are stored in rows of sealed boxes in
a highly secure vault. The vault is made of steel, located inside a mountain, and
requires the use of many codes to enter. The cold environment preserves the
seeds even if power to the facility is lost.

them for later use. Many rare seeds have already been sent to the vault and have
contributed to the effort to maintain biodiversity.
D The Svalbard Seed Vault is considered the greatest store of crop diversity to
date. Efforts to build the seed vault began when scientists noticed that crop variety
had decreased significantly in recent years. The vault contains many rare and
