About this episode

The episode discusses the presence and impact of microplastics in Lake Tahoe with expert Madison Wallner.

Lake Tahoe is one of California’s natural jewels but it is under siege and increasingly awash in plastic wastes, as visitors carelessly dispose of bottles and packages and discarded items degrade into small pieces washed into the lake. What happens to that stuff? As we have been learning, microplastics are everywhere, in the environment and in our bodies. What are their impacts on people, animals and nature? Join host Ronnie Lipschutz for a conversation with Madison “Madio” Wallner, a UCSC PhD student in Environmental Science, who is studying microplastics and tire particles in Tahoe’s bottom sediments.
