PUERTO MALDONADO, Peru (AP) — Eight Peruvian navy personnel jumped from a helicopter into a clearing carved out of the Amazon rainforest by illegal gold miners along the Malinowski River in Peru’s Madre de Dios region, sending sand and dust swirling as they ran toward the mining site. The forest gave way to giant holes gouged into the earth and filled with opaque, muddy water, gasoline and other chemicals glistening on the surface. Makeshift wooden mining platforms straddled the pools, surrounded by pumps and thick plastic tubes used to suck up and sift through sediment for tiny particles of gold.As the troops closed in, several miners stood watching from a distance. The officer leading the patrol fired a warning shot into the air. Within seconds, they vanished into the forest.The raid over several days this week was part of an intensified government campaign against illegal gold mining in Madre de Dios, one of Peru’s most biodiverse regions, as authorities try to stop the activity from advancing into protected areas of the Amazon. Mining has stripped away vast areas of rainforest, leaving behind a scarred landscape of contaminated pools and altered rivers in the hunt for lucrative gold. Mercury used to separate gold from sediment has contaminated waterways, wildlife and people, including Indigenous communities that depend heavily on fish.
