Climate change and habitat destruction may have already caused the loss of more than one-tenth of the world's terrestrial genetic diversity, according to new research led by Carnegie's Moises Exposito-Alonso and published in Science. This means that it may already be too late to meet the United Nations' proposed target, announced last year, of protecting 90 percent of genetic diversity for every species by 2030, and that we have to act fast to prevent further losses.
