Accumulated garbage, spreading some 200,000 square meters and piling up one meter high, is washed down by recent torrential rain into the Lechangxia Dam, posing a severe threat to the people and environment downstream. Located on the border of Guangdong and Hunan provinces, the dam is a major flood control facility for the Beijiang River, the northern tributary of the Pearl River in southern China. (Photo/Xinhua)
