This episode of The Children's Hour focuses on pollution, which is a problem around the globe, but there are ways to un-pollute dirty and contaminated places. How we do that is explained by chemist and journalist Dr. Marina Philip, and we check in with mycologist Peter McCoy from the world's first school for mycology, Mycologos about how mushrooms can transform some of our most toxic pollutants into building materials and more. We also hear from the kids in the Extinction Diaries about the problem of plastic pollution worldwide. Kids can help solve this international crisis and we learn how. This show is mixed with great music from the Beat Buds, Zee Avi, Mister G, One More Song, Ellis Paul, Earthworm Ensemble and more.
