Science & Tech Spotlight: Microplastics in the Body and Environment

Why This Matters Across the globe, over 24 million tons of plastic (as much weight as 12 million cars) enter the environment each year. Larger plastics gradually break down into smaller microplastics, which can move into the organs, blood, and cells of humans and other animals.
