[阅读理解]Man is a land animal, but he is also closely tied to the sea. Throughout history the sea has served the needs of man. The sea has provided man with food and a convenient way to travel to many parts of the world. Today, nearly two―thirds of the world.s population live within 80 kilometers of the sea coast.In the modern technological world, the sea offers many resources to help mankind survive .

The development of strong, new materials has made this possible.The technology to harvest the sea continues to improve.
