While I totally agree, the underlying conflict is that Zoos over use the argument of preservation these days. On the other end they certainly have the need to stay entertainment venues, a conflict which they seldomly address.

Recently there was a obviously necessary mass culling of baboons in the Nuremberg zoo which shows some of the controversy [1]

They could have hunting preserves, basically areas sharedby predators and prey similar to nature as enrichment, but that would be cruelty for the cityZens.

Im argueing against nature preserves in poorer countries, where western nations deluded citizens pay to keep a piece of nature which are basically mirages of "intactness" in economic good times, vanishing from the earth entirely in economic bad times. Which the very same proponents usually argue for with degrowth arguments.
