Xavier Arbex, priest in Peru, advocates for victims of gold mining
Peru is among the world's top sources of precious metals. Mining is poisoning people and turning forests into wasteland.

For decades Xavier Arbex, a Catholic priest in a biodiverse region of Peru, has sought to bring attention to environmental and social devastation caused by illegal gold mining.
Peru is among the world’s most important sources of gold, copper, and silver. Mercury used in mining—some 90 metric tons annually, according to the Canadian group Artisanal Gold Council—exposes local people to high levels of the heavy metal. And tens of thousands of hectares of jungle are turned into wasteland every year.
“Forests, rivers, and streams are exploited mercilessly, then left barren and unusable,” Pope Francis said when he visited Peru last year. People are “used until someone gets tired of them, then abandoned.”
