Pollution is the most serious problem in the world. Pollution always goes with humans. There are many kinds of pollution.
Water pollution is one of the most serious kinds of pollution.
Water is very important to humans, because we can't live without water. But now water is becoming dirtier and dirtier. Many of us throw rubbish （垃圾）into rivers. Many factories are < polluting rivers, too.
I hope people could see this problem. If we don't protect（保护）or save water, the drinking water will become less and less. But what should we do? Here are some suggestions（建议）: First, we mustn't throw rubbish into rivers. Second, we should plant more trees on both sides of the rivers. Next, we should stop the factories polluting rivers. Then, after washing the vegetables, we can use the water to clean the floor. Finally, when we see someone wasting water, we should stop him or her.
At last, I would like to say "To protect water is to protect life." It's our job to protect and save water. Let's do it from now on.
