Great Ape Welfare

Our closest relatives face some of the most severe welfare threats of any animal — from captivity suffering to habitat loss and the bushmeat trade

Chimpanzees, gorillas, orangutans, and bonobos are our closest living relatives — sharing 96-98% of our DNA. They are cognitively sophisticated, emotionally complex, and socially rich animals. All four great ape genera are endangered or critically endangered. They face threats from habitat destruction, the wildlife trade, bushmeat hunting, and captivity — and in captivity, they often suffer severe psychological distress when their complex needs are unmet.

Captivity Welfare Challenges

Great apes in captivity frequently develop psychological disorders when their social and cognitive needs are unmet. Research documents: stereotypic rocking, self-directed aggression, hair-plucking (trichotillomania), coprophagy, and severe depression — particularly in animals that were isolated in early life, separated from mothers too young, or kept in barren environments. Zoo standards for great ape housing have improved significantly, but facilities without adequate group size, complexity, and cognitive enrichment still produce these outcomes. Solitary housing of great apes — still practiced in some facilities — is considered severely welfare-compromising by the scientific community.

Wild Great Ape Threats

Wild great apes face: deforestation and habitat fragmentation (affecting all species, especially orangutans in Borneo and Sumatra); the bushmeat trade (killing hundreds of thousands of great apes annually in Central Africa); infant capture for the pet and entertainment trades (involving killing the mother); and disease transmission from humans (respiratory diseases have devastated some populations). These threats cause direct suffering to individuals as well as population-level harm.

Sanctuary and Conservation Responses

Orangutan sanctuaries in Borneo (Borneo Orangutan Survival Foundation) have rescued, rehabilitated, and released hundreds of orangutans. Chimpanzee sanctuaries across Africa (Chimfunshi, Sweetwaters, Ngamba Island) provide lifelong care for ex-captive and bushmeat-orphaned individuals. These sanctuaries represent genuine welfare solutions and many engage with habitat protection and community conservation simultaneously.
