government to close off a little more than 4 square kilometers of this endangered reef in hopes that the coral and marine life would recover from overuse and overfishing. And it worked. But while the government invested $4 million in this experimental project, developers are investing $800 million to turn the region into a tourist mecca, beginning with the building of a dozen luxury hotels right on the water's edge. The project threatens the mangroves, which exist in a mutually dependent relationship with the coastline's ecosystems, including the reefs that support the fish we eat. All the ecosystems encompassed by coastal zones worldwide are mutually dependent; what affects one affects the others-and the more than 2 billion people who live in coastal regions.
