Chinanews, Wuhan, July 12 - Nearly all the fish in the Donghu Lake in Wuhan died recently, about 50 tons. The foul smell has spread to adjacent areas, arousing wide complaints.The fish were killed by polluted water; besides, local farmers had released too many fish fry into the lake, which had only made the problems worse."The pollution in the lake has long been a severe problem, but local environmental protection administration has never treated it seriously. In fact, we report the condition of the lake to them every year, and they just came, put some chemicals in the lake and collected some of the garbage in the lake, which was no use at all," said a resident living nearby.Our reporter also saw many drain outlets around the lake, discharging untreated sewage directly into the lake.
