The algae, which can suffocate marine life, is thought to be caused by pollution from agriculture and industry. The largest algal bloom ever recorded in China has turned the Yellow Sea green and may be related to pollution from agriculture and industry. In future the name may change yellow sea into Green Sea.
Officials in the city of Qingdao had used bulldozers to remove 7,335 tonnes of the growth from beaches according to the Xinhua news agency. The phenomenon has become an annual occurrence in the region over the past six summers. This year’s incident has swathed 28,900 sq km (11,158 sq miles), twice as much as the previous biggest bloom in 2008.
