FirstPrepare materials to be used
Draw a general frame.
And then color the little animals.
The most important step is to write our theme this time.
And write a sentence about protecting the ocean.
Finally, our handwritten newspaper is finished.
The ocean is an important source of food for human beings. 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 25000 kinds of fish in animals and more than 200 kinds of fish for human consumption. The ocean can provide green energy for human beings. The potential of ocean energy resources is quite large, including tidal energy, wave energy, temperature difference energy, salinity difference energy, ocean current energy, tidal current energy and so on. According to the estimation of American scholars, the theoretical reserve of ocean energy in the world is more than 1500 × 108 kW.73.8 × 108 kW can be developed and utilized, including wave energy of 27 × 108 kW, temperature difference energy of 20 × 108 kW, salinity difference energy of 26 × 108 kW, ocean current energy of 0.5 × 108 kW and tidal energy of 0.3 × 108 kW. The sea is an important channel for water transportation. Although the international ocean freight transportation has the disadvantages of low speed and high risk, it has large capacity, large volume, low freight and strong adaptability to goods.Making it the main mode of transport in international trade. 80% ~ 90% of the total amount of China's import and export goods are transported by sea. The ocean has brought so many benefits to our life and production, and more and more marine development has also caused harm to the ocean. On the other hand, people have always regarded it as a bottomless pit for dumping garbage and waste, while relying 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 can no longer bear the continuous pollution. We need to protect the ocean.
