Community-Wide Collective Suicide: Fixing Algal Blooms with Eyal Harel

In this episode of The Fixers Podcast, host Amrita Kumar talks with Eyal Harel, CEO and co-founder of BlueGreen Water Technologies, based in Israel, about tackling the algal blooms devastating lakes and oceans around the world—including the one that turned up in the Lincoln Memorial's Reflecting Pool.We explore how BlueGreen's reformulated treatments trigger what Eyal calls a "community-wide collective suicide" in toxic bacteria, using satellite remote sensing to guide treatment at unprecedented scale.It's a strategy built on working with nature rather than against it—once the toxic population collapses, biodiversity moves back in on its own. The conversation moves from the science of why water is such an underexplored, chaotic environment to a real-world case study in South Africa, where a lake serving half a million people went from a dead zone to a thriving ecosystem within weeks of treatment, and closes with how that project reshaped BlueGreen's entire business model around carbon credits.Whether you're drawn to the science of ecological restoration or curious what it takes to build a company in an industry investors run away from, this conversation will change how you think about water, climate mitigation, and letting nature do the heavy lifting.Learn more about BlueGreen Water Technologies at bluegreenwatertech.com.To stay up to date with more stories of people solving real problems, subscribe to Fixers, leave a review, and share the episode with friends who care about climate and water solutions.
