Question

Humans are land animals, but we are also closely connected to the sea. In history, the sea has given a lot to mankind. The sea has provided man with food and a better way to travel to different parts of the world.

In the modern world, the sea offers many resources to help mankind survive. Resources on land are going to meet the end. The sea, however, still can be hoped to satisfy man's needs.

The list of riches of the sea to be developed by man's technology is amazing. Oil and gas explorations have been carried out for nearly 30 years. Valuable minerals on the ocean floor are ready to be mined(开采).

Fish farming promises to be a good way to produce plenty of food. The culture of fish and shellfish is an ancient skill practiced in the past mainly by eastern 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(蒸汽) in a steamship. Ocean waves offer possible use as a source of energy.

Technology allows man to explore more deeply under the sea. The development of strong, new materials has made this possible.

The technology to harvest the sea continues to improve. Scientists believe that by the year 2050 the problems that prevent us from making full use of the food, minerals, and energy sources of the sea will be largely solved.
