16、the Internet. C Seeds on Ice Close to the North Pole, the remote and rocky Plateau Mountain in the Norwegian Svalbard Archipelago seems an unlikely spot for any global effort to safeguard agriculture. In this cold and deserted environment,no grains,no gardens and no trees can grow. Yet at the end of
17、 a 130-meter-long tunnel cut out of solid stone is a room filled with humanitys most precious treasure, the largest and most diverse seed collectionmore than a half billion seeds. A quiet rescue mission is under way. With growing evidence that unchecked climate change will seriously affect food prod
18、uction and threaten the diversity (多样性)of crops around the world,the Svalbard Global Seed Vault (保险库)represents a major step towards ensuring the preservation (It藏)of hundreds of thousands of crop varieties.

19、n the seeds: the genes that give one variety resistance to a particular pest and another variety tolerance for hot, dry weather.

The Seed Vault was built by optimists who wanted to do something to preserve options so that humanity and its crops might be bet
23、ter prepared for change. If it simply resupplied seed gene banks with samples those gene banks had lost, this would repay our efforts. The Seed Vault is about hope and commitmentabout what can be done if countries come together and work cooperatively to accomplish something significant,long-lasting,
