From ocean depths to mountain peaks, humans have littered the planet with tiny shards of plastic. We have even absorbed these microplastics into our bodies—with uncertain implications. Images of plastic pollution have become familiar: a turtle suffocated by a shopping bag, water bottles washed up on beaches, or the monstrous “Great Pacific Garbage Patch” of floating detritus.

They're everywhere: microplastics in oceans, air, and human bodies. (2022, July 4). Manila Standard, p. B4.
