A new report reveals the primate species in urgent need of help.
More than half of the world’s 633 primate species and subspecies are threatened with extinction, according to the IUCN Red List.
Now leading experts at the United Nations Convention on Biological Diversity have revealed the 25 most endangered primates of all, the species at the greatest risk of extinction and in need of urgent conservation measures.
Dr. Christopher Schwitzer, one of the editors of the Primates in Peril report, said, “The world’s primates are under increasing threat from human activities.” These include the destruction of forests, illegal wildlife trade and hunting for food.
Despite the report’s gloomy prognosis, several species featured on previous editions of the list, including Madagascar’s greater bamboo lemur, have begun to recover.
