1. Refuse to eat shark fin and encourage others to do the same.

Sharks are part of the biological chain. If there were no carnivorous sharks, there would be too many weak fish, and then there would be too few aquatic plants and plankton for small fish to survive. Then a large number of small fish will die because of lack of food, then the ecology will be further destroyed and the composition of seawater will even change. If this situation worsens further, it will cause the collapse of the biological world.

Therefore, any creature in nature has its inevitable value, and we can't measure its value by the direct benefits of animals to people. In order to protect the earth on which we live, human beings must protect sharks and other creatures.

Distribution range of sharks:

There are sharks in the Yellow Sea and Bohai Sea in the East China Sea. Sharks are generally distributed in the Yellow Sea, South China Sea, Bohai Sea and East China Sea, and blue sharks are the most widely distributed. There are nurse sharks in the southeast coast, Philippine sharks in the South China Sea and dog sharks in the East China Sea of China.

Sharks can't stand the low temperature, so most of the time they live in the Yangtze River estuary, the East China Sea, the South China Sea and the Beibu Gulf in China. Even with the high temperature in midsummer, few small sharks will enter the northern part of the Yellow Sea at high latitudes, and even less will enter the Bohai Sea.
