One of the primary functions of zoos is to participate in conservation efforts. Many zoos are involved in breeding programs for endangered species, which helps to increase population numbers and genetic diversity. For example, the World Association of Zoos and Aquariums (WAZA) coordinates global breeding programs for species like the giant panda, the African elephant, and the mountain gorilla. These programs not only help to protect these species but also contribute to the overall health of ecosystems.
