In the Christian world. . . it is believed that angels were created at the beginning, and that heaven was formed of them; and that the Devil or Satan was an angel of light, who, becoming rebellions, was cast down with his crew, and that this was the origin of hell.
Peter Singer
If zoos are like arks, then rare animals are like passengers on a voyage of the damned, never to find a port that will let them dock or a land in which they can live in peace. The real solution, of course, is to preserve the wild nature that created these animals and has the power to sustain them. But if it is really true that we are inevitably moving towards a world in which mountain gorillas can survive only in zoos, then we must ask whether it is really better for them to live in artificial environments of our design than not to be born at all.
