Humans Have Destroyed 97% Of Earth s Ecosystems Gizmodo 8 hrs ago Dharna Noor © Photo: Carl De Souza (Getty Images) Smoke rises from an illegally lit fire in Amazon rainforest reserve, south of Novo Progresso in Para state, Brazil, on August 15, 2020. Only 3% of land on Earth still qualifies as “ecologically intact,” with undisturbed habitats and healthy populations of its original animal species, grim new research shows. That’s a much bleaker picture than the one painted by previous assessments, which pegged that number much higher, estimating that 20% to 40% of land is still intact. But those analyses, focused specifically on habitat intactness, were mostly based on satellite imagery, which doesn’t provide much detail about what’s happening on the ground.
