Hot Dam: Why beavers are Britain’s new climate heroes
Summary
NPR’s Lauren Freyer explores how beavers, reintroduced to Britain after 400 years, are acting as "climate warriors" by building dams that mitigate flooding and restore biodiversity. While their engineering skills offer a cost-effective solution to urban flooding, as seen in London, the return of these rodents sparks conflict with farmers facing crop damage and legal restrictions. The episode highlights the complex balance between ecological benefits and agricultural challenges in modern rewilding efforts.
