The modern zoo, therefore, has developed dramatically as a major force in conserving biodiversity* worldwide. Zoos linked with the Association of Zoos and Aquariums participate in Species Survival Plan Programmes, which involve captive breeding, reintroduction programmes and public education to ensure the survival of many of the planet's threatened and endangered species. Captive breeding is the process of breeding animals outside their natural environment in restricted conditions such as farms, zoos or other closed areas.
It is a method used to increase the populations of endangered species, in order to prevent extinction. One of the main challenges facing captive breeding programmes, however, is maintaining genetic diversity.* Zoo staff are fully trained in this area, and manage the programmes carefully to ensure genetic variation. Another way in which zoos protect endangered species is through reintroduction programmes. These programmes release animals that have been in the zoo back into their natural habitats.
Finally, and perhaps most significantly, many zoos now concentrate on educating the public, particularly the younger generation. These zoos educate millions of visitors each year about endangered species and related conservation issues. Visiting the zoo not only raises money for conservation projects, but also reminds individuals about environmental issues.
