Chimpanzees, gorillas, bonobos and orangutans face habitat destruction, illegal hunting and the pet and entertainment trades. Sanctuaries provide refuge for survivors of these welfare crises.
Great apes are our closest relatives — their cognitive and emotional complexity means that welfare deprivation causes suffering equivalent in kind, if not quantity, to human suffering. Orphaned chimpanzees rescued from the pet trade require 20-30 years of sanctuary care before they can form stable social groups. Rehabilitation is a lifelong commitment. Habitat protection remains the most cost-effective welfare intervention at scale.
