"It is the sadness of zoos which haunts me. The purposeless existence of the animals. For the four hours we spend in a zoo, the animals spend four years, or fourteen, perhaps even longer -- if not in the same zoo then in others -- day and night; summer and winter. . . . This is not conservation and surely it is not education. No, it is 'entertainment.' Not comedy, however, but tragedy."
