Evidence-based zoo education programs that produce measurable conservation behavior change provide stronger welfare justification for captive animal display than programs producing only attitude change.
The welfare justification for displaying captive animals in zoo settings rests ultimately on whether the conservation benefits — knowledge, attitude, and behavior change — are real and substantial enough to justify the welfare costs of captivity. The evidence that visits produce knowledge gain and attitudinal change is reasonably strong; the evidence for durable behavior change is weaker and depends heavily on how education is implemented. Zoos that invest in evidence-based education — providing specific actions, follow-up engagement, and community reinforcement — have stronger welfare justification for their captive animal populations than those assuming a visit alone produces meaningful conservation outcomes.
