Modern zoos balance conservation goals with animal welfare, but individual animals in captivity often experience welfare compromises that require ethical examination even when institutional intentions are good.
The zoo welfare debate involves genuine tension between individual animal welfare and broader conservation goals. Captive animals may be protected from predation and disease, but often experience chronic stress from restricted space, lack of control over their environment, and proximity to humans and other stressors. Stereotypic behaviours are widely accepted indicators of poor welfare. The conservation argument for zoos depends on whether captive breeding and public engagement actually translate into meaningful wild population benefit - a question with mixed evidence. Critically examining zoo claims about conservation impact is compatible with appreciating genuine welfare improvements.
