, it’s even more necessary to establish adaptation and compensation strategies to reduce current harm, according to the study.
The study also established thresholds concerning the Earth’s biosphere. To maintain the functional integrity of human-modified ecosystems and the terrestrial benefits humans get from nature, such as pollination and water quality regulation, they identified that at least 20 to 25 percent diverse habitat in each square kilometer in human-modified lands is needed.
The proposed safe and just ESBs are scalable from a global level to a local one, Rockström says. In the study, they assessed the ESBs at a local scale, allowing them to determine which boundaries were crossed in certain regions and identify potential hotspots. The findings reveal that two or more safe and just boundaries have already been crossed for 52 percent of the world’s land surface, which affects about 86 percent of the global population.
