The lack of progress in reversing the declining global trend in biodiversity is partly due to a mismatch between how living nature is conceived and valued by the conservation movement on the one hand, and by many different people, including marginalized communities, on the other. Addressing this problem calls for a pluralistic perspective on biodiversity. This requires consideration of the use of the concept of biodiversity, willingness to expand its ambit, and engagement with the multiple and multi-level drivers of change. We propose ways for conservation science, policy and practice to deliver more effective and socially just conservation outcomes. Divergent conceptions of living nature between conservationists and other groups of people can hinder progress to protect biodiversity. This Perspective reflects on the use of the concept of biodiversity, willingness to expand its ambit, and engagement with the various drivers of change.
