Man can't live without water just as man can't live without air. So water is very important to us. Some people always think that we have enough water because we can see water everywhere around us. At home we drink water every day. We use water to wash clothes,to wash dishes,to take showers and so on.At work,we use water to put out fire, grow vegetables, to make things in factories and so on.
Do you believe there isn’t enough water on the Earth? Yes, it is true. In some big cities, there is not enough water for people to drink. In some dry areas, such as deserts, there are no rivers or lakes. It seldom rains. Water is much more valuable there. If we waste too much water, one day in the future, the last drop of water on the Earth will be our tear.
