Linda Walters researches microplastics in the Indian River Lagoon. Microplastics are smaller than 5 millimeters and most look like small fibers, while others look like tiny fragments.

“(There’s) at least a piece of plastic in every liter of water,” Walters said. “That’s scary.”

Our beautiful waters are filled with billions of microplastics, most of them too small to be seen with the naked eye.

Microplastics are so small that oysters filter feeding and take them in. On average, some of the oysters take up to 20 pieces.
