Seven-tenths of the earth is covered by water. However , we are still facing many water problems. Now there are fewer and fewer clean rivers and lakes. Many factories dump waste into rivers and lakes. The poison of the waste kill the fish and plants in the water. It also pollutes the rivers and lakes. Water is very important. Every life in the world can't live without wate, so we must take action to save water. For example, we should keep the tap closed when we are using a soap. If everyone tries his best, water problems will better

It is generally believed that there is a good supply of fresh water. But to our disappointment, the fact is just the opposite.
As we can see, the world population is growing rapidly day by day. So enough fresh water is needed to feed such a big population. What's more, with the development of industry, factories and vehicles produce poisonous gases or wastes, which consequently results in the pollution of water. Though fresh, a good amount of it can no longer be used. Only quite limited fresh water resource is available to human beings. So it's high time for us human beings to take quick action to protect water resource. Stop pollution and save water, otherwise, we cannot survive on the earth.
With fresh water, the world will be prosperous. (130words)
