Chinese swimmers driven away by smelly green algae Swimmers are being driven away from a popular coastal resort in north-east China after it was engulfed by algae. The oxygen-thirsty algae started growing quickly along the coast waters of Qingdao, a city in east China's Shandong Province, last month and its overpowering smell has kept many beachgoers at bay. Local authorities say the green algae, which poses no threat to humans, will be sent to a factory where it will be dried and ground to make animal food. Lorna Blount reports.
