Water is the source of our lives. Having water,we can do many things, such as washing hands,having a bath and brushing the teeth and so on.we can not live without water.
However, some of us are wasting too much water.They care nothing for turning off the tap after washing their hands.Worse,water pollution is more serious.Waste water is being poured continuously into rivers.
In a word,we must protect the water for our own future.
