Summary
The rapid decline of biodiversity predicts dire consequences for human society, according to the recent Global Assessment Report by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (1). The report notes that up to a million species are threatened with extinction (2) and that many benefits humans obtain from nature have decreased over the last 50 years, a decline likely continue until at least 2050. If transformative changes are to be implemented, scientists and policy-makers must address questions about the deterioration of nature and the locations that bear the greatest resulting burdens. On page 255 of this issue, Chaplin-Kramer et al. (3) address these questions by presenting global models of the current status and future trends of three key contributions from nature.
