About 1500 BC was when Queen Hatshepsut of Egypt decided to build a zoo, and about 500 years later around the year 1000 BC, the Chinese emperor Wen Wang founded the Garden of Intelligence. This was an enormous zoo that covered about 1,500 acres (607 hectares). Many small zoos were established between 1,000 and 400 BC by rulers from Northern Africa, India and China to show power and display wealth. To study animals and plants life, the ancient Greeks established public zoos. As part of their education, Greek students would visit the zoos. Near the end of the 1,400’s, global exploration brought Europeans to the New World. When explorers brought strange creatures back with them, it renewed the European’s interest in animals and zoos.

In most modern zoos the exhibits resemble the animal’s natural habitat better than most of the old styles of zoos. For example, in the case of an animal that comes from an African plain, the people at the zoo will try to create a copy of an African plain in the animal’s enclosure and will probably make natural boundaries so the animals do not feel too enclosed. The health care animals get at more modern zoos is very good. Specialists work on keeping the animals healthy and safe. Each animals diet has been researched in the wild so that it can receive the proper amounts of vitamins, nutrients and minerals.

Animals reserves are large sections of land used to conserve our Earth’s natural habitats and rare and endangered wildlife. It helps the animals by keeping them safe from hunters and poachers who would otherwise destroy massive numbers of animals each year.
