In this episode of Oceanography, host Clark Marchese talks with Julie Anderson, CEO and co-founder of Plastic Oceans International, about the Trees & Seas Film Festival and its “participatory film activism” model. We explore how curated films connect to on-the-ground efforts in global Blue Communities, turning awareness into cleanups, tree plantings, and policy conversations. Julie traces her path from witnessing a nurdle spill to building the SEE Positive Change film library, and we dig into timely themes—microplastics, ecotourism pressures, and how environmental stress can drive migration. Hear favorites like The Illusion of Abundance and House by the Sea, and learn how storytelling done locally and shared globally reframes who has the power to make change
