Unlike many titles on environmental issues that portend a dark future, Environmental Success Stories delves into the most daunting ecological and environmental challenges humankind has faced and shows how scientists, citizens, and a responsive public sector have dealt with them successfully. In addition to presenting the basic chemical and environmental science underlying problems like providing clean drinking water, removing DDT and lead from agriculture and our homes, and curtailing industrial pollution, this book also discusses the political actors, agency regulators, and community leaders who have collaborated to enact effective legislation. Sharing the stories of the people, organizations, and governments who have addressed these problems successfully, Frank M. Dunnivant explains how we might confront the world's largest and most complex environmental crisis: climate change. Now is the time for rededicated scientific exploration and enlightened citizen action to save our environment, and Dunnivant's book offers a stirring call to action.
