This second edition showcases all 12 of the original cases, thoroughly revised and updated. In addition, Layzer has added four new cases:
- Community activism propels the Dudley Street Neighborhood Association to fight for environmental justice and equitable redevelopment of a once-distressed area in the heart of Boston.
- The use of snowmobiles in Yellowstone National Park divides environmentalists into bitterly opposing camps: those who regard parks as playgrounds and support unlimited motorized access, and those who advocate more conservative management that emphasizes protection of the park's flora, fauna, and quiet serenity.
- In the tuna/dolphin and shrimp/turtle disputes, competing advocates debate whether U.S. environmental protection measures constitute non-tariff barriers to trade and, more broadly, whether trade liberalization is good for the environment.
- Opponents of growth management campaign to undermine the city of Portland's strict policies curbing urban sprawl, the most stringent in the nation.
Layzer provides maps, tables, figures, questions to consider, recommended readings, and useful websites to help readers think critically and actively about the issues raised in each case and facilitate further research.
