An international group called the Global Crop Diversity Trust is working on the project. The director of the group, Carp Fowler, spoke to New Scientist.

　　He said the project would let the world rebuild agriculture if, in his words, “the worst came to the worst.” Norway is expected to start work next year.

　　The project is expected to cost three million dollars.

　　Workers will drill deep in the side of a sandstone mountain. Temperatures in the area never rise above zero degrees Celsius.

　　The seeds will be protected behind concrete walls a meter thick and high­security doors.

　　The magazine report says the collection will represent the products of ten thousand years of farming. Most of the seeds at first will come from collections at seed banks in Africa, Asia and Latin America. To last a long time, seeds need to be kept in very low temperatures. Workers will not be present all the time. But they plan to replace the air inside the storage space each winter.

　　Winter temperatures on the island are about eighteen degrees below zero Celsius. The cold weather would protect the seeds even if the air could not be replaced.

　　Mr. Fowler says the proposed structure will be the world's most secure gene bank. He says the plant seeds would only be used when all other seeds are gone for some reason. Norway first proposed the idea in the 1980s. But security concerns delayed the plan.
