Zoos

Zoos are common around the world. The first zoo was established around 3,500 years ago by an Egyptian queen for her enjoyment.

Five hundred years later, the Chinese emperor established a huge zoo to show his power and wealth. Later, zoos were established for the purpose of studying animals.

Zoos were supposed to take good care of animals, but some of the early ones were dark holes or dirty cages. At that time, people became disgusted with the poor care the animals were given.

Later, these early zoos were replaced by scientific institutions. Animals were studied and kept in better conditions there. These research centers became the first modern zoos.

Because zoos want to treat animals well and encourage breeding, animals today are put in large, natural settings instead of small cages. They are fed a healthy diet and are watched carefully for any signs of disease.

Most zoos have specially trained veterinarians and a hospital for their animals. Today, animals in the zoos are treated well, and zoo breeding programs have saved many different types of animals.
