Waters cover seventy percent of the planet, but actually only three percent can be used. The others are frozen glaciers or not be able to be used. Because of the shortage of water, many people were exposed by diseases. Rivers are now polluted too. If we cannot stop polluting and wasting water, two-third of the world's population may face the lack of water. In addition, animals will die without water.
I think that we should use lesser water by using lesser time to bathe. Or using the water that we wash the dishes, vegetables and fruits to water the plants. We should also stop polluting the river by not throwing litter in it. As polluting river will make the animals to lose their lives and slowly become extinct. And very soon the Earth will be destroyed by us.
