ADVANTAGES, genetic technologies may potentially help scientists protect genetic diversity in endangered populations., can help scientists develop treatments for genetic disorders and some serious diseases., genetically modified crops can be more resistant to insects, diseases, or difficult weather conditions. This may help farmers produce more food., scientists can modify some foods to contain higher levels of certain nutrients., scientists can modify genes to better understand how diseases develop and how biological systems work., it may help prevent or treat certain genetic diseases by changing or correcting faulty gene, DISADVANTAGES, genetically modified organisms could have unexpected effects on human health, modified organisms could potentially affect ecosystems, other species, or biodiversity if they spread beyond controlled environments., genetic research and genetic treatments can be expensive, which may make them inaccessible to some people., changing one gene can sometimes have effects that scientists did not anticipate, especially in complex biological systems., some people argue that genetic engineering means “playing God” because humans are changing the natural characteristics of living organisms. They believe that there should be limits on how much humans interfere with nature., in the future, parents might want to choose certain characteristics of their children, such as physical traits or abilities. This could create serious ethical concerns.
