The Dirt on Plastic with Dr. Mary Beth Kirkham

Interview at 18:43. Just as the second half of the 20th century was all about the plastic revolution, the 21st century is going to be, among other things, about how we can clean up the world from the plastic revolution.

On this edition of Green Street Patti and Doug welcome soil biologist and educator Dr. Mary Beth Kirkham, a Distinguished Professor in the Department of Agronomy at Kansas State University. Dr. Kirkham has discovered how tiny plastic particles in soil are interfering with our food supply, and why it could turn out to be a big problem for our health and safety.
