Thick waves of green growth are washing onto the shores of China’s yellow sea. A massive bloom, caused by an abundance of nitrogen and other nutrients, has turned beaches into massive patches of seaweed shag carped. The algae poses a hazard to marine life in the sea, but it’s non-poisonus to humans. Which is good, because beachgoers have taken a liking to the green stuff. As workers slowly cart away more than 40,000 tons of seaweed, tourists have been turning themselves into swamp things and otherwise frolicking in the green sea. Way to make the most of a potentially icky situation, China.
