Did mining giant Anglo-American violate Chile's environmental laws?

Trucks belch out exhaust as they drive in and out of the gates of El Soldado, an open-cut copper mine owned by the British-based mining company Anglo American, in central Chile.
Jorge Ramirez, a community leader, lives with his wife and three children just a few kilometers from the mine, in El Melon. In the past, he says, the mine was only underground. He's angry that the facility has now turned into an open-cut mine too.
"The mine destroys nature and native forests," he says. "It pollutes the water, it also takes away our water because a lot of water is needed for mining processes."
Ramirez adds that the company is also responsible for a tailings pit, a lake of ground-up rock, water, and chemicals left over from the mining process. Ramirez thinks it endangers the community and describes it as a "time bomb."
