And the river ha been eriouly polluted,n be een from the color of it. Along thi "black" river, there are a few people elling freh water which mut have been taken from far away place.
At the firt glance, it i very trange to u how can people ell water along the river, but thi i the cae, becaue the water in thi river i undrinkable. Thi preent a eriou ocial problem--environmental pollution. With the development of economy, our living tandard have been greatly improved. But we can‘ t ignore the fact the air we take in and the water we drink today are not a freh and clean a they ued to be. Some kind of pollution can even be deadly to people. It i high time that we took ome meaure to olve the problem.I think we can firt call people‘ attention to thi problem o that they will be aware of the eriou conequence of it. Then,we can pa certain law to retrain the factorie from ending out wate. Finally,
