Two main aims of the zoos are highlighted by the author in the article. Firstly, zoos provide the environments that are suitable and represent some level of wilderness. Secondly, the zoos must provide entertainment to the visitors. But the zoos have been criticized by the author. One of the most important facts in these cases is the relationship between pornography and zoos as given by the authors. The way animals are represented in the zoos in the pictures has been very much compared with the sexual representation in pornography. From here, it can be realized that the animal representation is very offensive.

Firstly, the study does not mention or refer to the moral theories in relation to the animal rights. Secondly, use of animal meat a food or for industrial purposes has not been highlighted. The main aim of the third study is to highlight the ways in which animals are represented in the zoos, compared with sexual representation in pornography. The usage of non-human animals for the entertainment of humans is offensive. It is important that non-human animals are treated by taking into account the rights that they have of being respected.
