In 1922, Olaus Murie entered Alaska to study caribou and wildlife ecosystems

Olaus Murie began studying Alaskan caribou in 1922, which influenced ecological wildlife understanding. His brother Adolph later investigated wolves and Dall sheep, challenging predator control assumptions. Adolph’s research examined species interactions within the wider ecosystem of Mount McKinley. This work helped shift park management away from viewing predators solely as pests. The Muries’ ecological approach…

Study finds one-third of farmland drives two-thirds of farming’s nature loss

A global study reveals one-third of farmland causes two-thirds of farming’s environmental damage. Beef and dairy production significantly contribute to biodiversity loss and carbon storage decline. High-impact regions in South America and Asia face concentrated environmental degradation. International trade shifts these environmental impacts between exporting and importing nations. Targeted restoration of impacted land offers substantial…
