Zoo

A zoo (short for zoological garden; also called an animal park or menagerie) is a facility in which animals are kept within enclosures for public exhibition and often bred for conservation purposes.^[1]

The term zoological garden refers to zoology, the study of animals. The term is derived from the Ancient Greek ζῷον, zōion, 'animal', and the suffix -λογία, -logia, 'study of'. The abbreviation zoo was first used of the London Zoological Gardens, which was opened for scientific study in 1828, and to the public in 1847.^[2] The first modern zoo was the Tierpark Hagenbeck by Carl Hagenbeck in Germany. In the United States alone, zoos are visited by over 181 million people annually.^[3]
