Zoos are unethical because they are dangerous for animals

The argument

Zoos are immoral and cruel to animals. People should not be allowed to take animals from the wild and keep them in a small enclosure for profit and entertainment. Despite the benefits to education and research, all animals deserve to be free. The argument concedes the benefits deliberately, because its claim is that they are the wrong kind of consideration. If freedom is something an animal is owed, then what is gained by confining it — knowledge, public interest, revenue — cannot settle the question, since those gains accrue to people while the cost falls entirely on the animal that did not consent to bear it. The basis for that entitlement is what animals are. Animals are intelligent and are able to feel different emotions, so they deserve to be treated with humanity. This is not a marginal claim about a few species: lawyers argued for an elephant to be treated like a human due to their ability to think complexly, a case that shows the question of animal standing being pressed in the one forum whose job is to decide who counts as a subject of rights rather than an item of property. The practice of zoos is then said to confirm that animals are treated as the latter. Some zoos have no regard for life, choosing to kill their animals for senseless reasons. For example, the Copenhagen Zoo shot a healthy giraffe because it was not able to breed. Later, they killed four lions to make room for a new male. What these cases reveal is the logic of a collection rather than of care. An animal that cannot contribute to the breeding programme, or that occupies space needed for another, is disposed of — which is possible only if the animal was never regarded as having a claim of its own.

Premises

Counter-arguments

Zoos are more beneficial than harmful. They are able to provide advanced medical care and ensure the safety and wellbeing of each animal. Having exotic animals in captivity allows zoologists to research and understand them better, as well as educating others.

Rejecting the premises

[Rejecting P1] Granting that animals are intelligent and emotional establishes a duty of humane treatment, not a right to liberty. The premise slides between the two, and captivity with veterinary care, protection from predators and reliable food is not self-evidently worse for the individual animal than the wild. [Rejecting P2] 'Small enclosure for profit' describes the worst of the trade rather than the category. Accredited institutions are typically non-profit or reinvest in conservation and research, and enclosure standards are set by accreditation bodies the argument does not engage with. [Rejecting P3] The Copenhagen culls are offered as representative when they were condemned by other zoos internationally — evidence that the conduct falls outside professional norms rather than defining them.
