Marine Environmental Protection Free Edit Add Name

The ocean is an important source of human food. There are more than 200,000 species of organisms in the ocean, including about 180,000 species of animals and more than 20,000 species of plants. There are 25,000 species of fish in animals, and there are more than 200 species of fish that can be eaten by humans. The ocean can provide green energy for mankind. The potential of ocean energy resources is considerable, including tidal energy, wave energy, temperature difference energy, salinity difference energy, ocean current energy, tidal energy, etc. According to estimates by American scholars, the theoretical reserves of ocean energy in the world are more than 1500×108kW, and 73.8×108kW can be developed and utilized, of which wave energy is 27×108kW, temperature difference energy is 20×108kW, salt difference energy is 26×108kW, and ocean current energy is 0.5× 108kW, tidal energy 0.3×108kW. The ocean is an important channel for water transportation. Although international marine cargo transportation has the disadvantages of low speed and high risk, its large capacity, large volume, low freight, and strong adaptability to goods make it the main mode of transportation in international trade. 80% to 90% of my country's total import and export cargo transportation is carried out by ocean transportation. The ocean has brought so many benefits to our life and production, and more and more large-scale ocean development have also caused harm to the ocean. On the other hand, people have always regarded it as a bottomless pit for dumping garbage and at the same time rely on its inexhaustible source of rainwater. In fact, the ocean itself is very fragile and its self-purification ability is limited. Recently, there are more and more signs that the ocean is no longer able to withstand continuous pollution, and we must protect the ocean.
