Captive breeding programs are used to a) replenish the wild populations of endangered species b) bring in revenue to zoos c) breed exotic pets d) increase the number of zoos able to house a species e) decrease the genetic defects in wild populations of species

A) replenish the wild populations of endangered species

Often zoos and other wildlife preserves will remove a male and a female of an endangered animal and place them in captivity to encourage breeding in order to help boost the population of the endangered species. This can be seen in the California Condor. This huge bird was on the verge of extinction, but after going through a captive breeding program at San Diego Zoo in California, the species has multiplied and is continuing to grow.
