@WandererUber @Waldbrand Zoos exist to satisfy the white race's inherent curiosity about the world.
In life before internet and earlier before convenient long distance travel, when a European, young or old, would be told about fantastical creatures the description of which could often sound like something out of a fable, there's a good chance that they would wish that they could see such creatures with their own eyes. To fulfill that White Man's Wish zoos came into existence. By spending only a reasonable amount of time and money required to visit a capital city it became possible to satisfy the natural curiosity found in the aryan soul.
There's an argument to made that the need for these institutions has become obsolete with convenient airplane travel, videos and the internet, but the time period where they served a purpose not easily filled by other means was enough for them to become a staple of white culture.
