From Primarily Primates:
“This video features the chimpanzee known as Oliver, an individual ripped from Africa in the 1960s to become “one of the most exploited and studied chimpanzees in history.’ Oliver’s life stands as one of the saddest contemporary examples of humanity’s custom of controlling the rest of the planet’s inhabitants.”
Primarily Primates is a sanctuary for primates who have been used as research tools among other things. That is, it’s a place where labs send primates when they are done performing cruel and unnecessary experiments on them.
Primarily Primates is a controversial place. Notable animal organizations involved were: PETA and Friends of Animals. There is some discussion of the controversy on Wikipedia if you’re interested in reading the history.
