CEMEX Presents Hotspots Revisited.

MONTERREY N.L., Mexico -- CEMEX S.A. de C.V. (NYSE: CX) announced today the launch of Hotspots Revisited, produced by CEMEX, in collaboration with Conservation International, Agrupacion Sierra Madre, and the University of Virginia. Hotspots Revisited identifies 34 regions worldwide where 75 percent of the planet's most threatened mammals, birds, and amphibians survive within habitat covering just 2.3 percent of the Earth's surface, roughly equivalent to the combined areas of the five largest U.S. states.

The new book, which features nearly 300 photographs, contains the results of an in-depth reanalysis of global hotspots, a widely used prioritization strategy for allocating conservation dollars to areas where they can do the most good. The new analysis shows that an estimated 50 percent of all vascular plants and 42 percent of terrestrial vertebrates exist only in these 34 hotspots.

"Hotspots Revisited is the twelfth in our series of conservation books. Like its predecessors, the new book illustrates approaches to protect the world's biodiversity and works to promote a culture of environmental awareness within our communities and our society at large," said Armando J. Garcia, CEMEX's Executive Vice President of Development.

"The biodiversity hotspots are the environmental emergency rooms of our planet. This latest assessment underscores the value of the hotspots concept for defining urgent conservation priorities," said Russell A. Mittermeier, President of Conservation International and Co-Editor of the new book. "We must now act decisively to avoid losing these irreplaceable storehouses of Earth's life forms."

Hotspots Revisited was written by Russell Mittermeier, Gustavo A.B. da Fonseca, Michael Hoffmann, John Pilgrim, Thomas Brooks, Patricio Robles Gil, Cristina G. Mittermeier, and John Lamoreux. The book can be purchased on www.conservation.org.
