On the Trail of Illegal Gold Miners

Corcovado, a vast preserve on Costa Rica’s West Coast, is home to a Noah’s ark of critters, including jaguars, ocelots, anteaters, sloths, river otters, and crab-eating raccoons. As the price of gold has soared over the past decade, small groups of miners have invaded Corcovado, contaminating rivers and streams with toxic mercury used to extract gold from other minerals.
Ghana is another hot spot for illegal gold mining. A 2013 study found that the West African nation, which is the world’s second-largest gold producer, faces an environmental crisis as a result of illegal mining.
