Zoos increasingly justify captive animal keeping on conservation education grounds, but evidence for education impact and the welfare costs of display animals requires honest evaluation.
The education and conservation justifications for zoo keeping carry most weight when they are substantiated rather than assumed. Zoos that invest in welfare-optimized habitats, ranger-led education, and direct links to field conservation programmes create genuine conservation value that can justify the welfare costs of captivity for some species. Zoos that maintain animals in poor welfare conditions while citing education as justification are neither educating effectively nor meeting their welfare obligations.
