English composition: Wuchuan's seaside

It was sunny the other day, and my father took our family to the seaside to play. Everyone is very happy, and they were too excited to sleep the day before. We have prepared tools for playing with sand, goggles for diving and swimming rings for swimming. We must have a good time before going home.

As soon as we got to the seaside, we rushed to the seaside to build a castle. My sister and I took buckets of water and dug sand with shovels. Although we piled the castle high, the walls of the castle were washed away by the sea as soon as the waves hit the coast. My sister and I took some stones in front of the city wall, but we still couldn't stop the invasion of the waves. Finally, my father helped to dig a long and deep moat in front of the castle. When the waves come, they will flow into the moat first to protect the city walls from being washed away. My father is really smart.

Dad also took us diving. We saw clown fish, grouper and many unknown tropical fish in the sea. When they see us swimming, they should think that they have met a big fish that wants to eat them, right? The fly in the ointment is that seeing some rubbish in the sea from time to time has ruined our good mood of enjoying fish. We can see starfish, crabs, conchs and other marine life in the intertidal zone. Among them, starfish move as slowly as old people, so we can pick them up and observe their five brachiopods. My mother said that they have amazing regeneration ability, and some broken brachiopods can regenerate complete starfish. It's really amazing.

Today, besides visiting the seaside, we also found a lot of rubbish at the seaside. Before going home, we picked up the rubbish in plastic bags. Soon, the bag was full of bottles, glass bottles, plastic bags and other rubbish. I suddenly feel sorry for the fish. There are all kinds of fish and creatures in the ocean. The sea used to be clean and clear, but now it is dead and full of rubbish because of environmental pollution. I hope everyone will take care of nature and protect marine ecology, otherwise there will be fewer and fewer marine life, and we will not even see fish in the future!
