Once upon a time, there was a crystal clear river in front of my house, like a silver mirror, and these lovely ducklings. You can also see pebbles. The sky is blue and deep, the air is fresh and sweet, you can wash clothes and vegetables, and there are lovely and lively small fish. However, day after day, year after year, I don't know how many years and bags have passed, and every household throws garbage into the crystal clear river and puts dead mice into it. All the trees by the river are dead, so are the small fish, and there are no pebbles left. The silver mirror is gone and the duckling is dead. The air is fresh and pleasant. I smell it with my nose. It stinks. I heard the river crying and asked what was wrong with it. What happened to it? It says, "People throw rubbish at me. Can you help me? " "yes."
I asked someone to pick up the garbage. The garbage in the river is gone and clean, and now it has become a silver mirror. The river said, "Thank you." I said, "You're welcome." Since then, humans have stopped throwing things into the river. If human beings do not cherish and love nature, they will naturally be brutally punished.
