Vaca Muerta, Argentina, is one of the world's largest shale oil and gas deposits, that deposit is also home to the indigenous Mapuche people. In 2013, a new deal saw U.S. energy giant Chevron (energy) enter Vaca Muerta, opening the region for the first time to the international oil and gas industry. In collaboration with The Guardian, FA investigated a local Mapuche community's claim that the oil and gas industry has damaged their ancestral land, eroded their traditional ways of life and irreversibly damaged the environment.
