Modern zoos aim to balance conservation contribution through breeding programs and education with the welfare trade-offs inherent in captive animal keeping.
Zoo conservation contributions are genuine but do not automatically justify welfare trade-offs for individual animals. The ethical framework for modern zoos must weigh conservation benefits against individual welfare costs honestly. Facilities that cannot provide adequate welfare for species with complex needs should transition those species to sanctuaries or wild programs rather than maintaining populations for visitor attraction. Excellent zoos contribute both meaningful conservation and high individual welfare.
