As someone currently reading Greenpeace - The Inside Story: How a Group of Ecologists, Journalists, and Visionaries Changed the World. I'll just rebuttal Walt's post with "shut up ya face!" : P

Book Description From Booklist
A handful of pacifists and antinuclear activists came together in Vancouver to protest atmospheric atomic bomb tests and in 1970 transformed themselves into the fledgling environmental movement's gutsiest and most galvanizing protest group. Greenpeace rapidly evolved into an international association that made ecology a household word, brought the "save the whales" effort to world headlines, and outed the ocean dumping of radioactive and toxic waste, among many other revolutionary accomplishments. Journalist Weyler, who emigrated to Canada to protest the Vietnam War, was one of the founders, and now presents a gripping insider's chronicle of Greenpeace's daring high-seas protests of illegal whaling operations, exposure of the brutal hunting of baby harp seals, and paradigm-altering success in disseminating a vision of the sanctity of life. Weyler also charts painful conflicts among a remarkable group of intense individuals, whom he divides into the "mystics and the mechanics," including Greenpeace's impassioned and spiritual first leader, the newspaper columnist Robert Hunter, whose courage, "unorthodox shrewdness," and brilliant use of the media made Greenpeace a force to be reckoned with. Weyler's capacious, affecting history is stirring testimony to the power of committed citizens.
