Chimpanzees in zoos face unique welfare challenges given their high intelligence, complex social needs, and close evolutionary relationship to humans. Meeting their needs requires sophisticated, science-based care.
Chimpanzees in captivity face welfare challenges that arise directly from their exceptional cognitive and social complexity. Boredom, social deprivation, and lack of cognitive stimulation cause psychological suffering that manifests as stereotypic behaviors, self-directed aggression, and depression. Research has documented PTSD-like symptoms in chimpanzees rescued from entertainment industries. The capacity for suffering in chimpanzees is extraordinarily high - matching their cognitive capacity. This creates a profound ethical responsibility for zoos to provide environments that genuinely meet their needs, or to reconsider keeping them at all.
