 The CZA was formed to bring Indian zoos up to international standards.Before the CZA was formed, many zoos were poorly managed, with unsuitable animal enclosures and little or no breeding records of animals, which caused inbreeding and hybridization (genetic pollution, as in one case where an Asiatic lion were cross-bred with an African lion).The Central Zoo Authority has been constituted under the section 38A of Wild Life (Protection) Act 1972.
