Microplastics in Lake Tahoe: How did They get There? What are they Doing?

With Madison “Madio” Wallner

on Sustainability Now!  December 21st, 2025, 5-6 PM on KSQD FM

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.
