　　The floors of the ocean contain many riches that can be used by man. Oil and chemicals and minerals are already taken from the sea. By using nuclear (核) energy, ocean water can be turned into fresh water by removing the salt. In the near future, it is possible for human beings to produce food from farms under the sea. Food grown in the sea could help meet the needs of the fast-increasing population all over the world, thousands of which go hungry every day. About 10----15% of the world population don't have enough food. Some scientists believe that someday the sea will be used to make electric power. This would help meet the need for more power for the world's industries. The decreasing supply of coal, oil and gasoline shows the need to find new kinds of power is urgent.
