The importance of protection of water
Water is important of human and plants.As we know there are much water in the river and ocean.However the amount of water suitable to drink is limited.Water is very precious to our human beings for cooking,drinking and so on.However,now the water is become worse and worse,and we can see water pollution everywhere.Many factories pull the dirty water into rivers,and throw rubbish into the rivers,so we can't find any clean rivers anymore.
As teenagers,we should try our best to stop these behaviors.We should do from small things,to protect our water.Such as reusing the used water,water the plants with used water.It is our duty to protect the water because if we don't save water,the last drop of water would our tear drop.
