question: This chapter looks at the stated goals of zoo mission statements and provides examples of how zoos are addressing their missions. Moreover, with the pressure of zoos to become biological conservation mentors, zoos assume five roles as the executor of the relationship between society and nature. First, zoos take on the role of the “model citizen” by conveying a conservation message. They advocate for a sensible, sustainable use of natural resources and promote less wasteful, green-building alternatives. Many zoological institutions are developing organizational plans that include the use of solar, wind, and thermal power in their daily operations. Additionally, they are growing food for the animals, composting, and using recycled materials in their exhibit design. Second, zoos are maintaining a viable and genetically diverse collection. Zoos are managed under the premise that wildlife conservation is of foremost importance. As zoological institutions have become more active in field studies, their research findings are being applied to larger conservation efforts. Moreover, the conservation research that takes place in situ and ex situ is important in saving small fragmented wild populations. Third, zoos directly influence the attitudes and behaviors of the community in relation to the conservation of plants, animals, and habitats. Due to their urban locations within heavily populated cities, zoos have a unique geographic placement within the community. The urban location of zoos provides them with a unique opportunity to influence government policy. Fourth, the zoo is a conservation mentor. Through mentoring efforts, future generations of scientists and citizens will be more aware of the benefits of long-term conservation. As conservation mentors, zoos must lead the public to become citizen conservationist. Fifth, zoos are a place for people to learn basic facts about organisms and their behavior.
