How to Change the World chronicles the adventures of an eclectic group of young pioneers - Canadian hippie journalists, photographers, musicians, scientists, and American draft dodgers - who set out to stop Richard Nixon's atomic bomb tests in Amchitka, Alaska, and end up creating the worldwide green movement. Greenpeace was founded on tight knit, passionate friendships forged in Vancouver in the early 1970s. Together they pioneered a template for environmental activism which mixed daring iconic feats and worldwide media: placing small rubber inflatables between harpooners and whales, blocking ice-breaking sealing ships with their bodies, spraying the pelts of baby seals with dye to make them valueless in the fur market. The group had a prescient understanding of the power of media, knowing that the advent of global mass communications meant that the image had become a more effective tool for change than the strike or the demonstration.
