How to Change the World is an insightful and candid documentary about the formation of Greenpeace in 1971 by a small group of environmentalists and activists in Vancouver, British Columbia. Beginning with their attempt to disrupt U.S. nuclear testing in Amchitka, Alaska, the film follows their subsequent efforts to thwart commercial whaling in the Pacific, their anti-sealing campaign in Newfoundland, and their ongoing efforts to defend the natural world against what they perceive as excessive human intervention and abuse. How to Change the World is as much a poignant tale of inspired activism as it is an interesting study of the organization’s early tribulations: idealism vs. anarchy, social movement vs. organizational structure (or lack thereof) and leadership vs. disunity. The voice of co-founder Robert Hunter (de facto leader of Greenpeace from inception) is heard posthumously throughout via narrator Barry Pepper, and it adds an impassioned air of gravitas to the film, detailing the many complexities Greenpeace experienced over the course of its early years of growth and development. A compelling and educational viewing experience.
