Nature Positive Paper

Halting and reversing biodiversity loss by 2030 critical to avoid disastrous effects on human well-being

Written by 11 leading co-authors in specialty focus areas. Published by Frontiers in Science.
Launched April 9th, 2026.

This paper represents collaboration at its best. A team of interdisciplinary co-authors from Canada, the United States of America, Europe, the United Kingdom, China, Brazil and India, came together to create this roadmap.
