There is a river near my hometown.There are many weeping willows by the river,and many fish swim in the river.Every morning or evening,people will come here morning exercise and walking.But in recent years, many factories buil by the river.Weeping willow leaves the river was covered with a thick layer of dust.The fish in the river began to move,and some even died.River scenerty isn't as beautiful.Had clear water into a dark,and people don't come here exercise.
Proctect the water of every people on the earth share of responsibility.If we don't proctect the water,then the world will be the last drop of out tears.
