In his new documentary Fog Eaters, filmmaker Kyle Baker follows environmental toxicologist Peter Weiss-Penzias and a team of researchers investigating unusually high levels of methylmercury in mountain lions along California’s central coast. Tracing mercury pollution through the food web, the researchers ultimately tie it back to an unlikely source: coastal fog.

In this episode of Terra Verde, host Hannah Wilton speaks Baker about the scientific discoveries at the center of film. They explore the legacy of mercury mining and pollution across the Bay Area and the enduring presence of fog in the region’s ecology and cultural imagination. Baker also reflects on his creative process, multispecies storytelling, and the interconnectedness of our ecologies.
