Do we need to build an ark to preserve species and ecosystems? In Marc Chagall′s painting "Noah′s Ark" featured on the cover, Noah and his family are gathering in all the creatures of the world on the ark to preserve them for future genewrations. This classic tale of stewardship and economic foresight raises many questions and holds valuable insights for us as we struggle against the pressures of population and concumption in the 21st century. How hard should we strive to preserve species and ecosystems for generations to come? How much pollution is too much? Is government up to the job? How can we do better? How can we resolve global issues? These are just a few of the many thought–provoking questions explored in Eban Goodstein′s Third Edition of ECONOMICS AND THE ENVIRONMENT. Goodstein offers in–depth treatment of important issues at the cutting edge of environmental policy debates, and equips readers with the tools necessary to analyze these issues–just as an economist would. The Third Edition is updated with several new topics and appendices, including: The latest economic thinking on the two big marketable permit systems: the Acid Rain Program and LA Basin trading (Chapter 7) The international global winning treaty, the Kyoto Protocol (Chapters 1 and 23) The "double–dividend" debate (Chapter 9) New appendices on game theory and the safe minimum standard, an indifference curve approach to WTP–WTA disparities, and a hybrid tax permit system for greenhouse gas control
