The first preprint on our new LIFE metric for global biodiversity is now available. It is under review, so feedback would be very welcome. LIFE stands for Land-cover change Impacts on Future Extinctions and represents a significant computational achievement - we generated global maps at 1 arc-minute resolution covering 29,153 terrestrial vertebrate species. The metric quantifies the marginal changes in expected extinctions from either converting natural vegetation to agriculture or restoring farmland to natural habitat. By coupling the persistence score approach with high-performance computing, we've created a tool that integrates information on species richness, endemism, and past habitat loss, offering unprecedented opportunities to estimate extinction impacts from scales ranging from individual dietary choices to global protected area development.
