Zoos are museums of animals, therefore keeping animals neat and healthy was part of the business.
However, as humans realized that irreversible damage done to the natural habitats would cause the extinction of animals, institutions such as the San Diego Zoo have become part of a conservation plan. Ra ndall Herren is a senior keeper in the Sun Bear forest area at the Zoo. Even though the zoo brings an impression of an unnatural environment, the Zoo provides as close as possible to the natural habitat to the animals. The Zoo only trains animals for medical purposes. If the animals are trained for medical purposes, especially crate training, they will be less stressed during vaccinations or annual exams.
