A cynical move is underway to promote a new, powerful, and troubling technology known as “gene drives” for use in conservation. This is not just your everyday genetic modification, known as “GMO”; it is a (129) new technology, which creates “mutagenic chain reactions” that can reshape living systems in unimaginable ways. Gene drives represent the next frontier of genetic engineering, synthetic biology, and gene editing. The technology (130) the standard rules of genetic inheritance, ensuring that a trait, delivered by humans into an organism’s DNA using advanced gene-editing technology, spreads to all (131) generations, thereby altering the future of the entire species. It is a biological tool with unprecedented power. Yet, instead of taking time to consider fully the (132) ethical, ecological, and social issues, many are aggressively promoting gene-drive technology for use in conservation. One proposal aims to protect native birds on Hawaii’s Kauai Island by using gene drives to reduce the population of a species of mosquito that carries avian malaria. Anotherplan, championed by a conservation (133) that includes US and Australian government agencies, would eradicate invasive, bird-harming mice on islands by introducing (134) mice that prevent them from producing female offspring. Creating the “daughterless mouse” would be the first step toward so-called Genetic Biocontrol of Invasive Rodents (GBIRd), designed to cause deliberate extinctions of “pest” species like rats, to save “favored” species, such as (135) birds.
