Scientists show how we can anticipate rather than react to extinction in mammals

Researchers developed a model that predicts which species are at risk of becoming threatened or extinct based on climate change, human population growth, and land use patterns. The study aims to shift conservation efforts from reactive to proactive, enabling the protection of species before they reach threatened status.
