My hometown is in a village in Hunan province.In the past ,it's a place full of green trees ,the river was clean,and the air was fresh.
Over the past years,it changed,and developed a lot.People here all have built new houses,almost every family own a motorbike,and some family even have cars.People are richer than before.However,many trees have been cut down,the river is dirty,the air becomes thick with dust.
In some ways, the development has brought some good things, but it has also causes much environment pollution. I think we should take action to reduce the pollution.
