Man is a land animal, but he is also closely tied to the sea. Throughout history

 Man is a land animal, but he is also closely tied to the sea. Throughouthistory the sea has served the needs of man. The sea has provided man with foodand a convenient way to travel to many parts of the world. Today, nearlytwo—thirds of the world’s population live within 80 kilometers of the seacoast.

   In the modern technological world, the sea offers many resources to helpmankind survive. Resources on land are beginning to be used up. The sea,however, still can be hoped to supply many of man’s needs.

   The list of riches of the sea yet to be developed by man’s technology isimmense. Oil and gas explorations have been carried out for nearly 30 years.Valuable amounts of minerals exist on the ocean floor ready to be mined.

   Fish farming promises to be a good way to produce large quantities of food. Theculture of fish and shellfish (贝类动物) is an ancient skillpractised in the past mainly by Oriental people.

   Besides oil and gas, the sea may offer new sources of energy. Experts believethat the warm temperature of the ocean can be used in a way similar to thesteam in a steamship. Ocean currents and waves offer possible use as a sourceof energy.

   Technology is enabling man to explore ever more deeply under the sea. Thedevelopment of strong, new materials has made this possible.

   The technology to harvest the sea continues to improve. Experts believe that bythe year 2020 the problems that prevent us from exploiting fully the food,minerals, and energy sources of the sea will be largely solved.
