Visiting the zoo is often a joyful part of childhood. Some people say that zoos help educate people about animals and can help with conservation. Other people say that animals should be able to live in the wild. Young readers may have never considered this issue before, so learning the arguments and facts can help open their mind to new ideas about a familiar situation. This book provides readers with tools—including clear arguments, fact boxes, and a graphic organizer—to make their own informed opinion on the topic of zoo animals. Readers will gain a deep understanding of the topic in this introduction to critical thinking.
