A zoo is an establishment where captive animals are kept for display to the public. Many people think of a zoo as a place for leisure, amusement, and a place for enjoyment. Although the primary idea of zoos was entertainment, over the years, zoos have transformed into centers for wildlife conservation and environmental education.
People value the opportunity to see animals they would never otherwise get the possibility to see. This perhaps the closest to wildlife that many city people may get, and so zoos provide a unique opportunity to start an interest and love for animals.
