The first reason for having zoos is that they allow people to see wild animals that they could not see otherwise. Zoos are the only places for most people who live in cities to see wild animals. Seeing wild animals on nature documentary programs or in books is not the same thing as seeing animals in real life. Zoos educate proplr about wild animals and teach them to understand and care about them. That is why there are school trips to the zoo. Where the zookeepers tell students about the animals.
