Mining and natural exploitation has had environmental consequences. The region of Guajira is undergoing an accelerated desertification with the disappearances of forests, land, and water sources, due to the increase in coal production. Social consequences or lack of development in resource rich areas is common. 11 million Colombians survive on less than one dollar a day. Over 65% of these live in mining zones. There are 3.5 million children out of school, and the most critical situation is in the mining zone of Choco, Bolivar, and Sucre.
