Captive Breeding Programs in Zoos Could Be Important for Biodiversity

Captive breeding programs in zoos could be important for biodiversity in the wild because:

A) even if a species goes extinct in the wild, there will still be members of the species in zoos.
B) a threatened species with low population sizes can be bred in zoos to increase their total global population size.
C) individuals raised in zoos could be released into the wild in order to reestablish natural populations.
D) endangered species in zoos provide a way to preserve genetic diversity for the species.
