Water in the desertVisit a small town in Coahuila, Mexico called Cuatro Ciénegas where spring pools and years of isolation have resulted in uniquely endemic species evolving in isolation, similar to the Galapagos Islands. These marshlands in the desert basin contain over 70 creatures found no where else in the world, promising vast research potential. Find out how the town has changed over the years and how researchers, townspeople, landowners and the government have begun working together to enact sustainable water policies and protection for the many endangered plants and animals of Cuatro Ciénegas.
