The documentary "Razing Liberty Square” shows what happens in Miami as sea levels rise and the rich move inland, encroaching on residents of the Liberty Square public housing project. The film tells the story of a historically Black community faced with a $300-million-dollar “revitalization” of their neighborhood. In this episode, hear from a resident and climate activist, Valencia Gunder, who says she’s fighting a new form of racial injustice: climate gentrification.
