An overflow crowd came to March Fourth Friday to see A Fierce Green Fire, a historical look at the modern environment movement from the early 20th century to today. Gathering in small groups after the film, people expressed conflicting emotions: awe and appreciation of the accomplishments of dedicated and passionate activists, despair at the current magnitude of the climate (and other) problems, and optimism that so many people are now involved in fighting for change. To paraphrase a quote from the film, “We’re not a movement, it’s larger than that. It’s the planet’s immune response to the disease that has infected it.”
