Most people love animals. Many children's books use animals as the main characters. Many people look after animals as pets. The love for animals may be why both children and adults (成年人) enjoy going to zoos.
In the past, zoos were usually started by rich people. The first zoo was started by a queen in Egypt in 1500 BC. Raising animals was a way for people to show they were wealthy and powerful. Sadly, the animals in the early zoos were not treated well. They didn't receive enough attention or care.
Today, zoos still bring people pleasure, but they try to protect animals and teach people as well. Zoos must follow rules. People must provide animals with a clean place to live, food and water, and health care. In this way, the rules help protect the animals.
Some people think the rules are not enough. They want to do more to protect the animals they love. For example, people disapproved of the use of some large animals in shows. They thought the zoos didn't have enough space for the animals to show. They also thought the animals were not treated properly. With so many people against the shows, the zoos decided to make a change.
People see animals in zoos. At the same time, they try to learn about and protect them. Both people and animals can get a lot from each other.
