Expert Stuart Leiderman has stated that “ecological protections are biological indicators of environmental quality”, an affirmation that has been contrasted by a recent study conducted in the United States. The damage caused by man in the environment has forced some 25 million people to leave their home, their lands and their family. Everything points out that within 50 years we will suffer more these “ecological migrations”, which will mostly be “ecological refugees”.

Floods, desertification, pests and hydrogeological projects are the main causes of emigration. In China, for example, the reservoir being built on the Yanzijiang River will force one million people to leave their home.
