In the twenty-first century, the idea that we are all connected is almost a cliché, though it is little understood and rarely acted upon. One twentieth-century social movement understood this concept at its core. It is, in the eyes of many, the most important ever: the environmental movement. It seeks nothing less than saving the planet from its most destructive force—humanity. Inspired by New York Times environmental journalist, Philip Shabecoff’s, book, director Mark Kitchell returns to the Sundance Film Festival (Berkeley in the Sixties won the documentary Audience Award in 1990) with a must-see film, shot and edited over four years, that documents crucial moments in the history of environmental activism. Dramatic personalities and lush archival images—many never seen before—bring pivotal moments to life in five chapters depicting five stories across five decades. Each illustrates the power of activism and commitment at a unique historical moment, often at tremendous personal cost. A film that will inspire and provoke, A Fierce Green Fire challenges us to rethink our past, our present, and our future on Earth.
