I completely support the point that zoos should be abolished. Wild animals are supposed to be in the 'wild' and not kept inside a cage. National reserves and parks are fine as the animals are free but animals being kept in zoos do not benefit in any way.
People in support of zoos should be asked how they would feel if an alien kidnapped them and took them to their planet far away from home and preserved them as models of public display in a cage for the alien population's entertainment?
I'm quite sure of the answer to that and I feel wild animals being caged in a zoo feel the same. They are best in their natural habitat and that is exactly where they should be.
