Zoos should be banned
A steelman map of the public fight over zoos — arguments for and against, with sources and assumptions.

Keeping wild animals on public display (zoos, menageries; aquaria in the same fight). Sanctuaries and breeding without a paying audience are a third camp. Farm animals and pets are not the claim here.
AGAINST 5
Empirical — moderateP1
A visit is the only mass contact most people will ever have with a wild animal that is not a screen
The education studies find a small, real bump in biodiversity knowledge. Small across millions of visits is still a lot of people. A ban trades that contact for a documentary.
Empirical — moderateP1
Some species only exist because zoos bred them when the wild was empty
California condors went to 27 birds in cages, then back out. Przewalski's horses went extinct in the wild and came back from zoo studbooks. That is not a gift shop. It is why a ban on the institutions that ran those programmes is not a conservation policy.
Empirical — moderateP1
The conservation budget is small next to tickets — and still one of the larger private conservation budgets on earth
WAZA members put hundreds of millions of dollars a year into field conservation and claim to be among the largest non-state funders. A ban that kills the gate kills that cheque unless a state writes a replacement.
Logically validP1
Clubb and Mason did not say 'ban zoos' — they said stop keeping the species that cannot cope
The Nature paper that FOR leans on already names the other half: lemurs and snow leopards can thrive; polar bears and some wide-ranging carnivores do not. That is a collection list, not a padlock on the gate.
Logically validP1
The wild is not a kindness machine, and a ban does not create a spare continent
Release is not available for most animals now in houses. A padlock on the zoo is a one-way trip into overcrowded sanctuaries or a cull. That is not a welfare win until the third camp actually has the space.

FOR 5
Empirical — moderateP1
The animals people come to see are the ones that fare worst in a cage
Wide-ranging carnivores pace, and their cubs die more in captivity. Polar bears, lions, tigers and the other headline species are a mismatch for an enclosure. A ban is how you stop using those animals as the draw.
Empirical — moderateP1
A five-point bump on a biodiversity quiz does not pay for a life in an enclosure
The best global visitor studies find a small rise in self-reported biodiversity knowledge after a visit. That is not nothing. It is not a justification for keeping a wide-ranging animal on show.
Empirical — moderateP1
The business is tickets — conservation is a side budget
Zoos and aquariums count hundreds of millions of visits. Their field-conservation spend is real and still small next to the visitor machine. A display ban would kill the show. It would not, by itself, kill every breeding programme.
Empirical — moderateP1
Tanks are the same fight — an orca is not a goldfish
Aquaria are in the claim. For wide-ranging marine mammals, the box is a tank. Welfare papers on captive orcas are contested on lifespan tables and not contested on the basic mismatch of range, social structure, and concrete.
Logically validP1
A sanctuary without a paying audience is not a zoo — do not smuggle it into the ban
Rescue, breeding for release, and lifetime care of animals that cannot go back are a different institution. Public display of wild animals is the thing being banned. Shut the show. Keep the hospital.
