Good morning, everybody. Today I'd like to tell you something about zoos. Zoos are very old. The first zoo was built in Egypt more than 4,500 years ago. But zoos then were different from zoos today. Early zoos were for kings and queens. Then later, zoos were open only for rich people. These zoos were built for the fun of the rich.
In China, around 3,000 years ago, an emperor created a very big zoo. It was about 1,500 acres. He gave the zoo an interesting name. He called it the "Garden of Intelligence."
The ancient Greeks built zoos, too. They built them so that they could study animal and plant life. Students in Greece had to visit the zoos as part of their education.
