Just 3% of world’s ecosystems remain intact, study suggests

Tierr@_de_N@die: No too much time left, reintroducing species lost could help in certain areas but climate change is not going certainly to help.

Previous analyses have identified wilderness areas based largely on satellite images and estimated that 20-40% of the Earth’s surface is little affected by humans. However, the scientists behind the new study argue that forests, savannah and tundra can appear intact from above but that, on the ground, vital species are missing. Elephants, for example, spread seeds and create important clearings in forests, while wolves can control populations of deer and elk.
