This picture was taken on a beach, and I can tell that it's a beach clean-up. About eight high school students in yellow vests and gloves are picking up trash. Right in front, a girl is bending down to pick up a plastic bottle with a long tool, and a boy is dragging a heavy trash bag. I think beach clean-ups are helpful, but they can't solve the problem alone. The trash on the beach consists mostly of plastic, and new trash comes in with every wave. So people need to use less plastic in their daily lives. Otherwise, a new layer of trash will cover the sand again the next week. Let me describe the picture in more detail. On the sand, there's an old fishing net with a bunch of bottles caught in it. A little further away, two students are sorting trash into blue and green bins. In the background, the waves are rolling in, and a white lighthouse stands under the blue sky.
