Microplastics Corrupted Our Planet. Here’s What We Can Do.

Plastic is designed to last. And last it does. Often composed of “forever chemicals” which take thousands of years to break down, it flakes throughout its life into microplastics — fragments, fibers and films less than 5 millimeters long. Microplastics are everywhere: they’re in our air, our water and our food, and they’re in our own bodies. And their effect on human health is still largely unknown, writes Wired science journalist Matt Simon in his new book “A Poison Like No Other.” Simon joins us to discuss the extent of the microplastic threat and what we can do.
