However, the next picture surprised me. People use fishing nets to catch marine animals such as dolphins, sea turtles and sharks. Then after cruelly cut off the shark's fins and tail, and threw them into the sea, we know that the shark can't swim without the fin, and will die because of excessive blood loss. They struggled painfully in the sea, and finally sank to the bottom of the sea. What a tragic scene! The public service advertisement made by Yao Ming said it well-"If there is no sale, there will be no killing." Let us act together, starting from me: refuse to eat marine life, wild animals! I saw in the book that shark fins and tails can be made into expensive "shark fins" on people's tables. In fact, a bowl of shark fin is not as nutritious as a bowl of egg custard, and once the sharks become extinct, the number of small fishes grows wildly, which will eat up plankton. On the earth, 70% of the oxygen comes from plankton. Without them, the consequences would be disastrous!
In the photos taken from the satellite, we can see that the azure ocean is gradually becoming dirty due to people's discharge of sewage into the ocean, the earth's environment has become completely unrecognizable, and the extinction rate of animals is thousands of times faster than before.
Fortunately, human beings have realized their mistakes and have begun to protect marine life. Nature’s self-repair ability is very strong. Coupled with human consciousness, it is not too late to protect the ocean. I hope that in the near future, the battered earth will return to her original beauty.
