While this argument is valid to a point, it only helps children become familiar with certain species of animals. (“10 facts about the zoo”). But that doesn't mean it's reasonable to keep them locked in their cages. “Instead, animals should be allowed to roam freely in sanctuaries and national parks, as this would allow children and people to witness the interactions between nature and wild animals. Creating sanctuaries will also help scientists in their study of these animals, as they will be able to study the creatures unrestricted and close to home, instead of those kept in cages and forced to behave in only one way . This will also help raise awareness about endangered or endangered species.”.
