Zoos are passe'. I stopped going to zoos long ago when I realized they were just prisions for undomesticated animals, who might be permitted to breed if if it suited the needs of the zoo, but otherwise would spend their lives in captive bordom until their ultimate demise.  The sadness in their faces and eyes became more than I could bear. I find it interesting that public sentiment railed against circuses that used wild animals for their shows until they had to give in to public pressure, with many closing down due to same, but no one thinks twice about the suffering of zoo animals.
