Recent research out of Oregon State University found micro plastics in some mega-fauna.

Scientists estimated gray whales off the Oregon Coast ingest between 6.5 and 21 million micro particles per day, including micro plastics and fibers from clothing. To get to that number, they looked at the micro-particles in two things: the tiny zooplankton that whales eat and the whale’s poop.

Susanne Brander is an associate professor at OSU. She said the effect of the toxins on whales isn’t known, but her research with fish and other organisms shows something called food dilution: “Which basically means t...
