Our beautiful earth has been seriously polluted. The river weeps for its polluted water, and the blue sky is sad that it is no longer blue. We can go without food for ten days, but we cannot go without water for ten days. If your hands are dirty, wash them with water; if your clothes are dirty, wash them with water. . . . . If the water is dirty, what do we use to wash it with? Currently, 60% of the world's regions face water shortages, 20% of the population has difficulty obtaining clean water, and 1.2 billion people are short of water. We can use water from washed rice to water the flowers, and we can also use water from washed clothes to mop the floor. To save water, you have to start with small things. Let's take action!
If we want to be qualified environmental protection guards, we should start from small things.
