48、rtificial waste kills countless ocean lives every year.There are two main reasons for these problems. First of all, the discharge of untreated industrial waste water from coastal industries is the main cause of serious pollution of coastal marine water quality. Second, overfishing in the fishing industry destroys the ocean life chain. Therefore, I think the government should strengthen the supervision of the coastal enterprises and set up the closed season to ensure the fish breeding.Yours,Li Hua
