Gold demand puts Peru’s Amazon at greater risk from mercury poisoning, bishop warns
5 minute read Updated: Yesterday at 9:21 AM CDTBOGOTA, Colombia (AP) — As gold prices hover at record highs, a leading Catholic leader in Peru’s Amazon is urging countries that are destinations for the precious metal to help stem illegal mining that is poisoning rivers with mercury.
Miguel Ángel Cadenas, an Augustinian from Spain who has lived in Peru’s Amazon for three decades, said illegal mining has surged since the COVID-19 pandemic, citing the Tigre, Nanay, Napo and Putumayo rivers as some areas where communities are at risk.
Tests have found mercury levels in some fish above World Health Organization limits, and hair samples from local residents analyzed by scientists and doctors also showed elevated concentrations.
“We are in a delicate situation,” Cadenas told The Associated Press. “Given that the Amazonian diet is rich in fish, we are talking about food insecurity.”

3 minute read 9:24 AM CDTLLANOS DE CHALLE NATIONAL PARK, Chile (AP) — A rare bloom in Chile’s Atacama Desert has briefly transformed one of the world’s driest places into a dazzling carpet of fuchsia-colored wildflowers.
The arid region — considered the driest nonpolar desert on Earth, averaging around 2 millimeters (0.08 inches) of rainfall a year — was a riot of color this week after unusual downpours throughout the Southern Hemisphere’s winter months soaked the desert foothills and highlands.
Experts describe 2025 as among the Atacama’s wettest in recent years, with some high-elevation borderlands receiving up to 60 millimeters of rain (2.3 inches) in July and August.
Seeds from more than 200 flower species sit in the red and rocky soil of the Atacama Desert all year, awaiting the winter rains, said Víctor Ardiles, chief curator of botany at Chile’s National Museum of Natural History.
