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

has served the need 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 kms of the sea coast.

In the modern technological world, the sea offers many resources to help mankind

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 is impressive. Oil and gas explorations have been carried out for nearly

30 years. A lot of valuable minerals exist on the ocean floor ready to be mined.

Fish farming promises to be a good way to produce large quantities of food. The

culture of fish and shellfish is an ancient skill practiced in the past mainly by

Oriental

people.

Besides oil and gas, the sea may offer new sources of energy. Experts believe that the

warm temperature of the ocean can be used in a way similar to the steam in a steamship.

Ocean currents and waves offer possible use as a source of energy.

Technology is enabling man to explore ever more deeply under the sea. The

development of strong, new materials has made this possible.

The technology to harvest the sea continues to improve. Experts believe that by the

year 2050s the problems that prevent us from fully exploiting the food, minerals, and

energy sources of the sea will be largely solved.
