When the water returns: The rescue of Cuatro Ciénegas

A group of scientists led by Dr. Valeria Souza Saldívar has been working for more than twenty years to bring water back to Cuatro Ciénegas, one of the most biodiverse places in the world. When the water returns is a documentary that tells that story, still unfinished, but mounted on the hope that the next generation of land owners have understood the importance of taking care of one of the most extraordinary places on the planet. A documentary by Alejandra González Romo and Cecilia Villaverde.
