With cloning becoming more common place, and scientists having perfected the process of DNA preservation, bringing back previously extinct species now seems a very real possibility. Within the next decade or two we could see zoos filled with rare or previously extinct animals, or even animal hybrids. Cloning has been used in zoos before, though not for extinct species, with San Diego Zoo having previously housed a banteng who had been cloned using cells from San Diego’s Frozen Zoo.
With scientific advances making cloning increasingly feasible, the main barriers to this are likely to be moral, financial and political. The high mortality rates associated with cloning, as well as the huge expense incurred, doesn’t make it very financially viable on a large scale. Also further questions need to be asked in regards to the ethics of it, as well as its potential implications in regards to conservation efforts and eco-tourism.
