The position of most modern zoos in Australasia, Europe, and North America, particularly those with scientific societies, is that they display wild animals primarily for the conservation of endangered species,Meizitang, as well as for research purposes and education, and Domestic cleaner secondarily for the entertainment of visitors,an argument disputed by critics. The Zoological Society of London states in its charter that its aim is "the advancement of Zoology and Animal Physiology and the introduction of new and curious subjects of the Animal Kingdom." It maintains two research institutes, the Nuffield Institute of Comparative Medicine and the Wellcome Institute of Comparative Physiology. In the U.S., the Penrose Research Laboratory of the Philadelphia Zoo focuses on the study of comparative pathology.The World Association of Zoos and Aquariums produced its first conservation strategy in 1993, and in November 2004, it adopted a new strategy that sets out the aims and mission of zoological gardens of the 21st century. The breeding of endangered species is coordinated by cooperative breeding programmes containing international studbooks and coordinators, who evaluate the roles of individual animals and institutions from a global or regional perspective, and there Domestic cleaner are regional programmes all over the world for the conservation of endangered species.In a modern zoo, about five animals are bred in captivity for every 20 animals on display. When they arrive at the zoo, the animals are placed in quarantine, and slowly acclimatized to enclosures which seek to mimic their natural environment. For example, some species of penguins may require refrigerated enclosures. Guidelines on necessary care for such animals is published in the International Zoo Yearbook. The animal rights organization People for the Ethical Treatment of Animals (PETA) argues against the position of the zoos that their main purpose is to undertake research and aid in conservation, alleging that most zoo research is geared toward Domestic cleaner finding new ways to breed and maintain animals in captivity. Andrew Linzey, director of the Oxford Centre for Animal Ethics, argues that zoos make a "minuscule contribution to conservation."
