In the middle of the peasant farmer reserve zone of the Cimitarra River Valley, there is a region that since the early nineties has been defended by the communities. Large rivers that seem to have no end, big trees that dream of touching the sky and countless animals that rule this land. It is about eighty thousand hectares of virgin forest that are known as The Yellow Line, where animals, plants, and water resources are protected. Where life is protected. Today this region is threatened.
