In China, a Lake’s Champion Imperils Himself
By JOSEPH KAHN
ZHOUTIE, China — Lake Tai, the center of China’s ancient “land of fish and rice,” succumbed this year to floods of industrial and agricultural waste. Toxic cyanobacteria, commonly referred to as pond scum, turned the big lake fluorescent green. The stench of decay choked anyone who came within a mile of its shores. At least two million people who live amid the canals, rice paddies and chemical plants around the lake had to stop drinking or cooking with their main source of water.
The outbreak confirmed the claims of a crusading peasant, Wu Lihong, who protested for more than a decade that the region’s thriving chemical industry, and its powerful friends in the local government, were destroying one of China’s ecological treasures. Mr. Wu, however, bore silent witness. Shortly before the algae crisis erupted in May, the authorities here in his hometown arrested him. In mid-August, with a fetid smell still wafting off the lake, a local court sentenced him to three years on an alchemy of charges that smacked of official retribution...
The country’s third largest freshwater body, Lake Tai, or Taihu in Chinese, has long provided the people of the lower Yangtze River Delta with both their wealth and their conception of natural beauty. It nurtured a bounty of the “three whites,” white shrimp, whitebait and whitefish, and a freshwater crustacean delicacy called the hairy crab. Natural and man-made streams irrigated rice paddies, and a network of canals ferried that produce far and wide. Along the lake’s northern reaches, near the city of Wuxi, placid waters and misty hills captured the imagination of Chinese for hundreds of years. The wealthy built gardens that featured the lake’s wrinkled, water-scarred limestone rocks set in groves of bamboo and chrysanthemum.
Since the 1950s, however, Lake Tai has been under assault. The authorities constructed dams and weirs to improve irrigation and control floods, disrupting the cleansing circulation of fresh water. Phosphates and other pollution-borne nutrients made the lake eutrophic, sucking out oxygen that fish need to survive. Even in its degraded state, Lake Tai made an ideal habitat for China’s chemical industry, which expanded prolifically in the 1980s. Chemical factories consume and discharge large quantities of water, which the lake provided and absorbed. Its canals made it easy to ship goods to the big industrial port city of Shanghai, downstream. With strong local government support, the northern arc of Lake Tai became home to 2,800 chemical plants...
