State of world’s ecosystems stress need for increased conservation efforts

May 1, 2021

The rate of environmental degradation can be alarming. In a recent article for Frontiers for Global Change, a team of ecological researchers claim only 3% of the world’s ecosystems remain intact.



While some areas maintain a healthy biodiversity (e.g., parts of the Amazon, Tundra, etc.), the majority of the world’s ecosystems have been severely impacted by human activity. This loss of biodiversity is intimately tied to species loss, with specific species playing a vital role in the functioning of ecosystems. The study in question surveyed 7,000 species in 1,500 habitats, mainly mammals but also birds, fish, plants, reptiles, and amphibians. Intriguingly, many of the low-impact areas have been those managed by indigenous communities.
