The older I get the more I think that zoos are not ethical. We should instead maintain and increase wilderness areas and if humans want to see animals they should be going there or maybe watch Webcams. It’s just not right to keep animals that are used to roam large areas in small confined areas. It’s pretty much guaranteed that they will develop psychological problems. And most people who have had extended contact with animals will agree that animals have emotions and personality. They can be happy, disappointed or depressed.
