But now, the sea has changed. The sea has become turbid, and it is no longer as clear as before. It is piles of rubbish washed ashore by the sea, not those lively and lovely fish. You must be curious to ask who did this, in fact, we humans did it. Some people throw rubbish into the sea after eating when they are playing at the seaside. What is even more hateful is that the factory unscrupulously discharges waste water into the sea, putting a dirty coat on the blue water.
Students, think about it. What will the world be like if the ocean leaves us one day? What should we do if the sea turns into smelly sewage? If it were me, I would never let the sea leave. As soon as I have time, I go to the seaside to pick up the garbage on the sea surface and put it in the trash can; And people who see littering will remind them. We must start from ourselves, from the small things around us, so that the sky-blue sea is no longer just our dream.
The ocean is the home of fish and our mother river. We should protect it, cherish it and prevent the sea from leaving us.
