Microplastics are everywhere -- even inside your body. It sounds scary, and it is. Just listen to University of Washington’s Dr. Sheela Sathyanarayana: “You want to try to get it out, but it’s something that can build up over time and potentially cause harm.” Plastic is everywhere you go, from car tires to food storage containers to PNW-beloved fleece and synthetic exercise clothes. And it never goes away.
