Insects are disappearing from the last places we thought were safe

A long-term study in Colorado reveals that insect populations are plummeting even in remote, undisturbed areas. Over two decades, flying insect abundance dropped by more than 70%, closely linked to rising summer temperatures. The results suggest that climate change, not just human land use, is driving massive losses. Scientists warn that biodiversity hotspots, especially mountain ecosystems, are now at serious risk.
