Gorillas, monkeys, lemurs and other primates are in danger of becoming extinct, and scientists say it’s our fault that our closest living relatives are in trouble, a new international study warns.
About 60 percent of the more than 500 primate species are "now threatened with extinction’’ and 3 out of 4 primate species have shrinking populations, according to a study published in Wednesday’s journal Science Advances .
The decline has been blamed on human activities including hunting, mining and oil drilling.
Logging, ranching and farming have also destroyed precious habitat in Africa, Asia and South America.
Primates, which include apes, monkeys and humans, have forward-facing eyes and grasping ability that set them apart from other mammals.
Scientists study them to learn about human behavior and evolution.
