Biodiversity map (IMAGE) Princeton University Caption The researchers found that as emissions increase (gray), the loss of biodiversity (red) would be greatest in tropical waters, while polar species are at the highest risk of extinction. The researchers found that reversing greenhouse gas emissions could reduce the risk of extinction for marine life by more than 70%.
