Duckweeds block a Yangtze River tributary

Workers clean duckweed floating on the Pengxi River within Yunyang county of Chongqing municipality, May 27, 2010. Large amounts of duckweed rushed into the Pengxi after torrential rains struck Chongqing during middle and late May. The rising temperature accelerates its reproduction and it has blocked parts of the river. Up to now, 900 tons have been removed. [Photo/Asianewsphoto]
