Ep 10. Why Were Plastic Mirobeads Banned? Marine Debris and Sustainable Plastics

Plastic debris in our water is a huge pollution problem, and just one source of that pollution is the tiny microbeads that have been widely used in personal care products.

We discuss the recent federal ban on microbeads and what consumers can do to be more sustainable in our day-to-day use of plastics. Continue reading
