This report, compiled by 85 experts from across the world, reveals that nearly half of all primate species are now in danger of becoming extinct from destruction of tropical forests, illegal wildlife trade and commercial bushmeat hunting. The list includes five primate species from Madagascar, six from Africa, 11 from Asia, and three from Central and South America, all of which are the most in need of urgent conservation action.
