Bree Drummond was active in the Don't Make a Wave Committee, during the first Greenpeace campaign to Amchitka Island; was active in Greenpeace throughout the 1970s, and sailed on the 1976 whale campaign. In 1974, Drummond sat in a stand of cottonwood trees in North Vancouver to keep them from being felled, a campaign that lasted for 6 months, before Drummond was lured down by false promises, and the trees were eventually cut.
