Creatures in the deepest trenches of the sea are eating plastic
"A British research team captured amphipods, tiny shrimp-like crustaceans that scavenge on the seabed, from six of the world's deepest ocean trenches and took them back to their lab. There, they discovered that more than 80 percent of the amphipods had plastic fibers and particles in their digestive systems, known as the hindgut. The deeper the trench, the more fibers they found. In the
Mariana Trench, the deepest at more than seven miles beneath the waves in the western Pacific, the scientists found fibers in 100 percent of the samples–in every amphipod collected. Prior studies of plastic particles ingested by marine organisms caught near the surface have found far smaller percentages."
