Fishing nets are left on the dry lake bed of Poyang Lake, in Nanchang, East China's Jiangxi province, Sept 21, 2011. Poyang Lake - China's largest freshwater lake - is experiencing severe drought conditions. The lack of water is killing fish and inhibiting the growth of several kinds of grass that act as food for the migrant birds that will arrive at the lake in one month. [Photo/CFP]
