Green Algae Blankets China Coast

Green seaweed is blanketing the city of Qingdao in China in the worst ‘green tide’ algae infestation recorded in the region. According to Reuters, operations at the port city have not yet been affected, and officials have dispatched vessels to begin cleaning up the algae. It is expected that more than 1 million metric tons will be removed from the water.

The algal blooms have been appearing in Qingdao for 15 years, but experts say they have been made worse as temperatures rise and because seaweed is intensively farmed in a nearby region, washing fertilizers and sewage into the sea. The algae has a severe impact on the marine ecosystem as it deoxygenates the water and decays, giving off a toxic odor and making it difficult for other organisms to survive.
