Discussions on the welfare of nonhuman animals in zoos tend to focus on incremental improvements without addressing the underlying problem of captivity. But alterations to the conditions of zoo captivity are irrelevant for animals. Real zoo reform will involve working to completely change the landscape. We offer six necessary reforms to bring zoos into a more ethical future: (1) Shut down bad zoos, now; (2) stop exhibiting animals who cannot and never will do well in captivity; (3) stop killing healthy animals; (4) stop captive breeding; (5) stop moving animals around from one zoo to another; and (6) use the science of animal cognition and emotion on behalf of animals.

关于动物园中非人类动物的福利的讨论往往集中在逐步改进而不解决被圈养的根本问题上。但是，对动物园圈养条件的改变与动物无关。真正的动物园改革将涉及彻底改变景观的工作。我们提供六项必要的改革，以使动物园进入更符合道德的未来：（1）现在关闭不良动物园；（2）停止展出不能也永远不会在圈养中表现出色的动物；（三）停止杀死健康动物；（4）停止圈养繁殖；（5）停止将动物从一个动物园转移到另一个动物园；（6）代表动物运用动物认知和情感科学。
