Should zoos be closed down - or not?

Yes, they should be. Most zoo's breed animals for publication but if they breed to much most kill them off or sell them to hunting grounds for hunters sport. A lot of zoo's also have used their animals on experiments. The noise and children are traumatic for the animal's. Most zoo's mistreat their animals. The exact same zoo's that claim they traet them well. There's so much more information about cruelty in zoo's you'd have to research yourself. But if you knew what actually happened in zoo's I'm sure you'd want them closed down.
