Over the past two decades, a select group of small but highly effective grassroots organizations have achieved remarkable success in protecting endangered species and forests in the United States. The Rebirth of Environmentalism tells for the first time the story of these grassroots biodiversity groups. Author Douglas Bevington offers engaging case studies of three of the most influential biodiversity protection campaigns - the Headwaters Forest campaign, the 'zero cut' campaign on national forests, and the endangered species litigation campaign exemplified by the Center for Biological Diversity - providing the reader with an in-depth understanding of the experience of being involved in grassroots activism. Based on first-person interviews with key activist in these campaigns, the author explores the role of tactics, strategy, funding, organization, movement culture, and political conditions in shaping the influence of the groups. He also examines the challenging relationship between radicals and moderate groups within the environmental movement, and addresses how grassroots organizations were able to overcome constraints that had limited the advocacy of other environmental organizations. Filled with inspiring stories of activists, groups, and campaigns that most readers will not have encountered before, The Rebirth of Environmentalism explores how grassroots biodiversity groups have had such a big impact despite their scant resources, and presents valuable lessons that can help the environmental movement as a whole - as well as other social movements - become more effective.
