This comprehensive analysis of key issues affecting North American environmental policy provides an overview of how the United States, Mexico, and Canada differ in their environmental management approaches and capacity levels. It also explores how these differences play into cross-border cooperation on environmental problems, both before and after NAFTA, and presents a framework for making environmental interaction more effective in the future.</p><p>The authors compare the unique national contexts for environmental management in each country—including economic conditions, socio-cultural dynamics, and political decision-making frameworks. They provide four unique case studies to illustrate their arguments: protected areas and biodiversity; air pollution (smog); climate change; and genetically modified crops.</p>
