Water is very important to humans. We can’t live without water. The water suitable for drinking is becoming less and less. But some people don’t seem to care about this. They waste a lot

of water. They pour dirty water into rivers and pollute them. They throw rubbish into them,too. Many rivers and lakes are seriously polluted. We must do something to stop the pollution. We must protect the water as well as find ways to reuse it. If we don’t ,the last drop of water will be a teardrop.
