Animals living in modern zoos enjoy several advantages over animals in the wild;however, they must so suffer some disadvantages. One advantage of living in the zoo is that the animals are separated from their natural predators; they are protected and can, therefore, live without risk of being attacked. Another advantage is that they are regularly fed a special, well-balanced diet; thus, theydo not have to hunt for food or suffer times when food is hard to find. On the other hand, zoo animals face several disadvantages. The most important disadvantage is that since they do not have to hunt for food or face their enemies, some animalsbecame bored, discontented or even nervous. Another disadvantage is that zoo
visitors can endanger their lives. Some animals can pick up airborne diseases from humans.
