After publishing research in journal Bioscience assessing how much of the earth’s terrestrial biosphere is protected, researchers are calling for a Global Deal for Nature. This deal, explain the authors, would “promote increased habitat protection and restoration, national – and ecoregion – scale conservation strategies, and the empowerment of indigenous peoples to protect their sovereign lands.” The central accord of the Global Deal for Nature is to protect 50% of Earth’s terrestrial biosphere.
