The coral reef structure also buffers shorelines against waves‚ storms‚ and floods‚ helping to prevent loss of life‚ property damage‚ and erosion. Several million people live in U.S. coastal areas adjacent to or near coral reefs‚ and the well-being of their communities and economies is directly dependent on the health of nearby coral reefs. Reefs also protect the highly productive mangrove fisheries and wetlands along the coast‚ as well as ports and harbors and the economies they support. Globally
