First of all, what kind of terrible parent would let their kid swim in this?

In Qingdoo, Shandong Province of China, the coastal waters are covered with algae called enteromopha prolifera. The algae is not poisonous and doesn’t affect water quality, but there are concerns about how it may affect local sealife and whether it might spur a drop in tourism.

Researchers aren’t sure what’s behind the green invasion. One expert told CNN that it’s possible that the lush green algae plume  may have something to do with “the change in the environment.”

The algae now covers 200 square miles of the Yellow Sea and looks so thick that it resembles a fairway on a golf course.

Thanks to Mr. Cuomo for bringing this to the attention of the It’s Interesting community.
