Climate change and biodiversity loss are the two greatest environmental challenges of our time. The 2015 Paris climate agreement states that global warming must be limited to a rise in temperature of less than 2 oC above pre-industrial levels to avoid the greatest impacts of climate change1. This goal has served as a rallying point for global efforts to limit carbon emissions. However, a comparably clear, agreed target for the amount of natural space that should be conserved to address the biodiversity crisis has been much more elusive. Writing in BioScience, Dinerstein et al. 2 analyse the current level of ecosystem protection on a global scale, and propose a way to address the problem of biodiversity loss.
