The Salar de Atacama and Punta Negra (salt flat and high-Andean wetlands) are two ecosystems located in the middle of a desert in Chile. These have been damaged by over-exploitation of water and pollution caused by Minera Escondida, BHP’s biggest mining project in the country and the highest producing copper mine in the world. The mine has also harmed the livelihoods of indigenous communities in the Atacama Desert, especially the Peine community, in the locations nearest to where the company draws water.
Anti-union practices mean that BHP also shows scant respect for the rights of workers.
