Unfortunately laboratories all over the World still keep monkeys and chimpanzees in captivity and use them to test medicine and make-up, so that we can find cures fir diseases like HIV/AIDS and make sure lipsticks are safe to put on.
Chimpanzees are often used because their DNA is 99% identical to human DNA. It is terrible. Some of them have been locked up for 30 years and have never been outside. Not only that… They have purposely been infected with various diseases so that scientists could try new medicines on them.
Some have been brn in the laboratories. Others have been captured in the wild, mostly by shooting their mothers.
38 of them now live in their own 2500 km2 sanctuary. You just have to see their reactions when they go outside and see the sky for the first time and they feel the rays of the sun. It is heartwarming to see their joy.
