Millions of tons of plastic that should be floating around in the world's oceans are unaccounted for — and some of this plastic may end up on your plate.
Researchers (reporting in the Proceedings of the National Academy of Sciences) believe the answer lies in microplastics: pieces of plastic that measure less than five millimeters across. As debris drifts on the ocean, solar radiation and waves break it down into these millimeter-sized fragments, which researchers believe are being eaten by marine animals.
When marine animals eat the microplastics, they’re ingesting these toxins along with them — toxins that may then move up the food chain and into your fish tacos.
