As a species we have always looked for ways to be faster, stronger, smarter and live longer. Many improvements that we take for granted today; blood transfusions, vaccinations, and birth control seemed unnatural or immoral when they were first introduced. However, over time we became accustomed to these controls over our minds and bodies and used them to improve ourselves and our world. Imagine a society without diseases, cancers or hereditary disorders. Lifespan would increase and IQ would increase. Mental illness eliminated. Alzheimer's is gone. Hereditary problems, such as baldness eradicated. The technology exists to diagnose faulty DNA in pre-implantation embryos, allowing humans to create a stronger, healthier baby. Scientists insert a new/changed gene into a virus-like organism that enters the cell and inserts the new gene. Genetic modification is used to correct faulty genes that lead to genetic diseases or disorders; in simple terms, manipulating human genes to provide a brighter genetic future for humanity. In the future we may even be able to “cure” genetic diseases in embryos by replacing defective sections of DNA with healthy DNA, in a process called germline therapy. This has been performed on animal embryos but is currently illegal for humans. Terms like tailor-made babies, eugenics, or human genetic modification lead society to imagine future supermodels, professional athletes, and yes, even Frankenstein. An Internet search allows an individual to purchase sperm and/or eggs to satisfy the customer's desire. Perhaps the term “online ordering” is too harsh, but the concept is clear. Do you want a tall, thin, athletic, red-haired, freckled child with above-average intelligence? Select donors, pay the fee and receive the genetic lottery payment. The... center of paper... genes for debilitating diseases may have the gene adapted to eliminate the condition. The major obstacle right now is the illegality of human germline therapy. Similar practices already exist in plant alteration. Foreign DNA is inserted into the plant cell. These genetically modified foods can grow in climates or conditions where the plant would not normally thrive. Crops can resist diseases and insects more effectively, increase yields and provide better nutrients. Trait modification in plants has been extremely successful. The plant or animal then produces the desired proteins. The process is called "Pharming". Given the shortage of human organs available for transplantation, xenotransplantation is used. These animals are created specifically for human-animal cross transplantation. Hybrid genes inserted into the animal reduce rejection.
