Hello. Today, I want to talk about sea pollution because it’s a serious issue in the world right now. First of all, the main reason that oceans are polluted is marine debris. Most of it is ocean pollution of plastic. It creates a difficult environment for people to live in, and also causes fish which eats the trash to die in large numbers. Therefore, this not only reduces the amount of seafood we take in our meals, but also reduces the number of fishermen. They also preserve the marine environment, so a decrease in the number of fishermen could worsen the marine environment. In this way, this problem causes a negative spiral. Secondly, leakage of hazardous substances is also reasoning that oceans are polluted. For instance, oil spill due to ship accident, emissions of chemical substances from factories, and domestic wastewater are serious reasons. Therefore, not only people in jobs related to the sea, but we are also closely related to marine pollution, so we also should try to reduce the amount of wastewater we often use in our lives. I think there are many things that we can do to solute the problem. For example, we should avoid using plastic products, not throw trash on the beach, not use extra water. To sum up, we also need to face the problem of marine pollution.
