Take a tour of coral reefs around the world with the World Resources Institute’s Reefs at Risk project and Google Earth. The journey to each of the six coral reef regions provides an overview of the biodiversity of reef ecosystems, their importance to people and local economies, and the types and magnitudes of threats that reefs face, illustrated with vibrant underwater footage of coral reefs and photos of activities that influence reef condition.

The Reefs at Risk project raises awareness of threats to coral reefs and provides information and tools to manage coastal habitats more effectively. For more information about the Reefs at Risk Project, visit http://www.wri.org/reefs .
