Coastal eutrophication is an increasing problem in China, due to their massive use of fertilizers.
Large blooms of blooms of blue-green algae are clogging parts of the sailing course at one of China’s Olympic sites in Quindoa. Algae are being manually removed by a thousand boats and thousands of people at (AFP, AP, Guardian, NYT, and photos from Xinmin). Bloomberg news writes:
Warmer waters, increased rainfall and high levels of nutrients in the ocean brought about the algae explosion along vast stretches of the 800-kilometer (500-mile) coastline, according to the Qingdao Weather Bureau.
Qingdao, located 830 kilometers from Beijing, is mobilizing more than 1,000 fishing boats to scoop up the algae and contain the outbreak, Wang said.
“We can only haul the blue-green algae manually and we’re doing all we can with our arms full and by the boat-load,” said Wang, a sailing spokesman for the Beijing Games organizing committee. “All you can see is fishing boats along the coast.”
