Modern zoos justify their existence partly through conservation programs. Understanding the relationship between zoo conservation activities and the welfare of individual animals in their collections is important.
The welfare-conservation tension in zoos is real and should not be dismissed. Using an individual animal's suffering to justify conservation goals creates an ethical framework similar to using individual humans in ways that harm them for collective benefit — a standard most ethical frameworks reject. The most welfare-positive zoo conservation model is one where animals used for conservation programs are also given the highest possible welfare standards, not treated as instruments. Visitors who care about animal welfare and conservation can support zoos that meet both standards rather than accepting a trade-off.
