You are the mayor of a midsize U.S. town on the Colorado River between Mexico and Arizona. Pollution from factories on both sides of the U.S.-Mexico border has contaminated your community and the Colorado River. The North American Free Trade Agreement (NAFTA) requires the U.S. government to pay for environmental cleanup in the United States. Yet critics accuse both the U.S. and Mexican governments of not doing enough to safeguard the environment along the border. As mayor, what can you do to persuade business leaders and governmental officials to adhere to environmental standards? Which body do you think presents your biggest challenge: the Arizona state legislature, the U.S. government, or the Mexican government? What can business leaders do if governments ignore their environmental responsibilities?
