This book seeks to provide the fundamentals in each major area, such as air pollution, water pollution, hazardous waste and toxic pollutant regulation, protection of endangered species, and the National Environmental Policy Act, without overloading the professor and student with exhaustive and unnecessary detail. Landmark cases are provided, as are recent cases highlighting the most topical and significant areas under development in each area. The organization of the book is easily adaptable to a teaching agenda that emphasizes only one or two substantive areas or attempts to hit the fundamentals of several areas. It also includes international aspects of environmental law.
