Blue-green algae appears in Taihu Lake again

 

Blue-green algae is seen on the surface of Taihu Lake in this recent photo taken in Yixing, East China's Jiangsu Province. Outbreaks of blue-green algae, which sparked last year's water shortage crisis in Wuxi, Jiangsu Province, may hit Taihu Lake again this summer, say some scientists and top environmental officials.
