One Way Zoos can Decrease Biodiversity

One reason that zoos can decrease biodiversity of Chilean flamingos, is that if there are a couple of Flamingos, there is not a large enough gene pool. There can be genetic mutations in the eggs due to too much inbreeding, and the baby Flamingo will have difficulties living. Many zoos have more than a couple of flamingos which will help to increase the percentage of healthy Flamingos. On the other hand, some zoos have a little population Flamingos since they are threatend, and this can decrease the biodiversity of the Chilean Flamingo. As a result of this, more Chilean Flamingos will die, decreasing the population.
