北极深处的种子库：守护世界粮食的未来
Deep inside a snowy mountain in Norway, there is a special room. It is not for gold or money. It holds millions of seeds from around the world. This is the Svalbard Global Seed Vault.
Why store seeds in a cold mountain? The vault is like a safe. It protects seeds from war, fires, and floods. If a big disaster happens, the seeds can help farmers plant again. It is a backup for our food supply.
