The Third Edition is updated to take account of new developments in the law and new regulations and cases where applicable. Some areas of particular interest will be recent developments in the international law of species protection and the WTO's recent "dolphin safe" label ruling, as well as the continuing saga of regulation (or not) of greenhouse gas emission under the Clean Air Act. The Third Edition will also emphasize the Obama Administration's new approach to environmental justice and present students with a relatively recent environmental case for the EPA's Environmental Appeals Board involving the operations of the Clean Air Act in Alaska. The Third Edition makes a concentrated effort to provide students and professors with "The Rest of the Story" -- the aftermath of cases and their continuing implications. In addition, the materials for professors will strive to provde professors with links to appropriate and short web videos for most days of class, to demonstrate to students how environmental law events play out in politics and culture.
