2. Two provocative questions. 1.Is free trade anti-environment? 2.is the World Trade Organization anti-environment?

3. The difficulty of addressing trans-border pollution is also shown through a discussion of the slow progress that NAFTA has made in attempting to ameliorate environmental problems along the Mexico-U.S. border.

In addition, the box on “Dolphins, Turtles, and the WTO” discusses two cases in which the WTO ruled against U.S. import restrictions intended to force foreign fishing fleets to adopt methods that reduce killing of dolphins and sea turtles.

9. Four examples of global environmental problems. 1.The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) attempts to prevent extinction of species by restricting or banning commercial trade in threatened species. It has been reasonably effective. 2.Overfishing is an example of the tragedy of the commons. It does not threaten extinction for most species, but rather it results in fish catches that are smaller than they could be. 3.Release of chlorofluorocarbons (CFCs) has resulted in ozone depletion. The Montreal Protocol, signed in 1987, is an example of an effective international agreement. It began with restrictions on trade in CFCs and has spread to reduction of production of CFCs. Concentrations of CFCs in the atmosphere are now slowly declining.

10. 4.The buildup of carbon dioxide and other greenhouse gasses in the atmosphere, and the likelihood that this is causing global warming. We cannot use science to predict exactly how much global warming will occur. A policy response consistent with the specificity rule is to tax consumption (or production) of fossil fuels on a nearly global scale. But an international agreement appears to be impossible to achieve. In 2001 the United States pulled out of the agreement made in the Kyoto Protocol.
