Modern zoos contribute to conservation through breeding programs, research, and public education, and welfare advocates argue conservation goals and individual animal welfare must be pursued together rather than traded off.
Zoo conservation and individual animal welfare are sometimes presented as competing priorities, but this framing is rejected by leading welfare scientists. Conservation rationale cannot justify chronic individual welfare harm to the animals in conservation programs. A welfare-positive zoo conservation program provides housing and management that meets individual animal welfare needs while contributing to species-level conservation goals. The two objectives are compatible and mutually reinforcing — animals with better welfare have better reproductive success in breeding programs. The institutional challenge is maintaining both commitments when resource constraints create pressure to prioritize one.
