Micro-plastics in our waters

The shoreline of the Raritan River in Newark is plastic soup. Plastic bags, bottles and broken Styrofoam stretch far and are piled high. But researchers are looking for the pieces you can't easily see: micro-plastics. A 2016 study by that group estimated 166 million pieces of plastic, mostly micro-plastics, are floating in the New York-New Jersey harbor estuary.
