Enviros are hailing a decision by Mexican environmental officials to reject a controversial proposal for a tourist resort on San Quintin Bay, a pristine inlet 185 miles south of the U.S. border. The federal National Ecology Institute, which reviews the environmental impact of projects proposed for undeveloped areas, gave a negative assessment to the $700 million plan to build eight hotels, three golf courses, and a 350-slip marina. Environmentalists in both Mexico and the U.S. have fought against the development, arguing that it would harm a sensitive waterway, spoil the local eco-friendly shellfish industry, and destroy key habitat for thousands for migratory geese. Still, enviros aren’t resting easy because the developers can appeal the decision or revise their proposal.
