Debunk Greely's Five Benefits For De-Extinction

Decent Essays

Imagine living in a world where bringing back extinct species is not just fantasy. A present-day world with massive flocks of passenger pigeons flying and with woolly mammoths walking the boreal forests of the north. Believe it or not, science and technology are on the cusp of making this happen. This process is known as de-extinction, the resurrecting of species that have died out. Stanford professor Hank Greely has identified five benefits for de-extinction: Advancement of scientific knowledge, increased technological progress, the environment, justice, and wonder. He lists five potential risks as well: animal welfare, human and animal health, the environment, politics, and morality (Greely).

Currently we are experiencing a catastrophic loss of biodiversity and Brand and his colleagues believe they have an answer by creating technologies that can revive extinct species. Is this even something that we should be pursuing? Conservation biologists are skeptical, to say the least, many of whom think we would not be reviving anything, just creating new species. There are three different approaches to de-extinction that seem most likely to succeed: cloning, back-breeding, and genetic engineering. Both back breeding and genetic engineering will not produce an animal that has exactly the same genome as the extinct species. Because of this, scientists favor cloning since it would yield a genomic twin to the extinct species (Sherkow and Greely ). Cloning is also by far the most controversial of the approaches. With cloning the risk to animal welfare is significant. Cloned animals often die in a painful manner. Cloning is not efficient and many animals are needed, in fact, less than 5% of potential clones develop into live offspring (Shapiro). Considering that cloning itself is extremely controversial, mix it with the revival of extinct species and many believe that we are playing god. In fact, Stuart Brand famously said, “We are as gods and might as well get good at
