China’s coastal city, Qingdao has been hit by a record algal bloom. The phenomenon has become an annual occurrence in the region over the past six years. However, the scale of this year’s algal bloom at 28,900 sq km was double the previous record bloom in 2008.
The algae itself is not toxic to humans or animals. Qingdao officials were clearing four to five million kilograms of the algae each day, according to local media. The collected algae will be dried to make animal food.
