If you want to admire animals buy a David Attenborough video. In Victorian times, we paid to visit asylums to laugh at the lunatics. It was claimed that the cash raised helped pay for the care of the poor unfortunates. The truth is that this needs global action by the UN to protect endangered species and habitats. Those causing damage should face the same sanctions as terrorists, with jail, property seizure and blacklisting. I consider destruction of our environment as dangerous, if not more so than terrorist activities. Zoos are a symptom of our lack of respect for our planet.
