Recommended: Potential impacts of genetic engineering
Gradually, but steadily scientists are edging their way further into the depths of unknown territory. This new innovative technology that has helped us achieve the unimaginable is now jeopardizing lives, and threatening our future. For decades, the evolving science of genetics has informed us and saved lives. Recently, procedures of genetic selection and modification are taking it further to eliminate genetic diseases. This complicated process that alters the genes of embryos is highly uncertain, and being activated too soon, with too much risk. So what, we may ask, are the actual long term effects of this procedure on not just its patients, but our population? Perhaps we will never know until it becomes too late to change. For this reason, I am strongly against genetic selection. Genetic selection was first tested in 1990, and since then has become more common. PGD (Preimplantation Genetic Diagnosis) is the technique used mostly for genetic selection. First, a cell from the embryo is extracted and then further analyzed. This includes various genetic screening methods, that can detect and diagnose over one-hundred different …show more content…
But is jumping into it faster worth all of the lives we will lose? Science is imperfect, and that is how every technology begins. We could be potentially destroying the natural gene pool, and all that we have evolved to be. Genetic selection is conducted on unknowing children that have no say in the creation of their life (Hanson). If it was unwanted by the child, they will feel as if they are living an artificial life. Loss of individuality caused by genetic selection creates a person who is not truly their parent’s child. Genetic selection allows the parent’s decision to possibly harm other siblings not involved (Hanson). Altering genes will possibly create cruel, unanticipated outcomes that will damage the life of the patient and those
Two of the most popular technologies used today for sex selection are, in vitro fertilization (IVF) and pre-implantation genetic diagnosis (PGD) (Ethics Committee of the American Society for Reproductive Medicine, 2015). IVF involves combining the egg cells and the sperm cells outside the uterus. Once fertilized, the egg is then implanted back into the women’s uterus or stored for future use.
Thesis : Children’s genes should be left untouched unless there is something terribly wrong, such as a sickness or disease.
Science and technology are rapidly advancing everyday; in some ways for the better, and in some, for worse. One extremely controversial advance is genetic engineering. As this technology has high potential to do great things, I believe the power genetic engineering is growing out of control. Although society wants to see this concept used to fight disease and illness, enhance people 's lives, and make agriculture more sustainable, there needs to be a point where a line is drawn.
...efits. It has the chance of messing up the whole human evolution process and potentially create a frightening future where the people with parents rich enough to have designer babies would hold all the power in society, and the citizens of lower social and economic status would not have the opportunity to move up the economic ladder due to all the opportunities being given away to the designed individuals with a superior genetic makeup. Additionally, at this point, we do not need designer babies and as cool as it sounds, the cons of designer babies seem to outweigh the pros. One new thing I learned about genetic technology is the process scientist use to create designer babies. This process is called inheritable genetic modification which modifies genes in eggs, sperm or early embryos and results in the altered genes being passed on to future generations (Steere).
In today’s advanced world, modern technology has enabled humans to accomplish tasks once thought to be purely science fiction. We live in a world today where everything is instant and custom designed. Who would have ever thought that one day parents would be able to design their children? Pre-implantation Genetic Diagnosis (PGD) is a “process [that] involves taking a 3day old embryo and pulling one of its six cells to test for genetic markers of disease.” (Edmonds0. Although this process is meant to help discover harmful diseases or complications like cancer, the idea of parents using this process to give their children what they consider “ideal traits” co0mes into question. Even though parents have a right to do what they think is best for their children, parents should not be allowed to genetically engineer their children because it can create new social and economic distinctions as well as destroy the idea that everyone is created equal no matter their differences.
Genetic research on human embryos, in correlation with the human genome, is the key to gene therapy, genetic diagnosis, and even to genetically engineered human beings. Knowing which gene controls what trait and causes what genetic disease will arm doctors with a powerful tool to treat their patients at the molecular level. On the other hand, this allows people to possibly manipulate genes to enhance specific traits or create the perfect baby. Genetic research on human embryos has two implications. A practical one in therapeutic research (to detect, and hopefully correct gene flaws), and then the potentiality of allowing parents to decide how their child should look (or in an extreme word, eugenics). The former, which at the present is wishful thinking, will be a reality in the future if the technology becomes feasible.
Shortly after the groundbreaking discovery of the structure of DNA in 1953, the scientific world was essentially given the ability to alter the genetic sequence of any living organism using a process known as 'genetic engineering'. By definition, genetic engineering is 'the deliberate modification of the characteristics of an organism by manipulating its genetic material', it is quite simply an unnatural process which defies the ordinary course of nature. As of yet, no devastating or permanent damage has been done. However, the unpredictable nature and unknown consequences genetic engineering holds is more than enough reason to be cautious, as one mistake could have irreversible and catastrophic effects.
It was not that long ago that there was an age of no internet or computers. Life around the world has changed dramatically in the past thirty years. Technology has advanced at faster rate than ever before. We now know about many new things including humans including our DNA. It seems as though, the more we learn about the make up of our bodies, the more we are learning how to manipulate them. Do we want to let science take over our natural way of life? Russell Powell of the Journal of Medicine & Philosophy agrees that there is a common worry that humans could be harmed by genetic engineering of humans. The problem, Powell says, could potentially lead to the extinction of human life. By reducing human genetic diversity, we could end up with a biological monoculture that may increase our susceptibility to deadly diseases.
Planned Parenthood Federation of America, an organization founded by Margaret Sanger in 1916, receives $500 million in federal funding every year. Mission statement: A reason for being. Planned Parenthood is one of the nation's prominent providers of inexpensive health care for women, men, and young people, and the country’s biggest provider of sex education (“Planned Parenthood at a Glance,” 2014).
Although humans have altered the genomes of species for thousands of years through artificial selection and other non-scientific means, the field of genetic engineering as we now know it did not begin until 1944 when DNA was first identified as the carrier of genetic information by Oswald Avery Colin McLeod and Maclyn McCarty (Stem Cell Research). In the following decades two more important discoveries occurred, first the 1953 discovery of the structure of DNA, by Watson and Crick, and next the 1973 discovery by Cohen and Boyer of a recombinant DNA technique which allowed the successful transfer of DNA into another organism. A year later Rudolf Jaenisch created the world’s first transgenic animal by introducing foreign DNA into a mouse embryo, an experiment that would set the stage for modern genetic engineering (Stem Cell Research). The commercialization of genetic engineering began largely in 1976 wh...
With all factors put into place the potential benefits of perfecting human genetic engineering far outweigh the negatives. A world with genetic engineering is a world that would be advantageous to all who undergo the procedure to positively modify their DNA. A genetically engineered human race will be able to have defeated all genetic mutations and diseases, rid humans of possible illnesses in young and unborn children, create drastically longer lifespans, and provide generations with a high quality of life. Human genetic engineering has progressed more rapidly than projected; according to Stephen Hawking, when human genetic engineering is consummated he hypothesizes, “With genetic engineering, we will be able to increase the complexity of our DNA, and improve the human race. But it will be a slow process, because one will have to wait about 18 years to see the effect of changes to the genetic code.”(Hawking). The advancements that genetic engineering will provide for the human race is incredible and we will soon benefit from science and technology more than ever
Human genetic engineering can provide humanity with the capability to construct “designer babies” as well as cure multiple hereditary diseases. This can be accomplished by changing a human’s genotype to produce a desired phenotype. The outcome could cure both birth defects and hereditary diseases such as cancer and AIDS. Human genetic engineering can also allow mankind to permanently remove a mutated gene through embryo screening as well as allow parents to choose the desired traits for their children. Negative outcomes of this technology may include the transmission of harmful diseases and the production of genetic mutations. The benefits of human genetic engineering outweigh the risks by providing mankind with cures to multiple deadly diseases.
The wonders of science fiction became reality with modern genetic technology. Genetic editing is a breakthrough in this field of science, allowing scientists to study and alter an organism’s DNA. In addition to such, they found ways to amend the genetic composition of human embryos, giving this discovery the name “designer babies.”. Discovering genetic editing techniques on human embryos sparked controversy all over the world. Despite this debate, , fixing human DNA can lead to a brighter future for the human race and the world.
The topic I choose for my persuasive speech is about the debate of Nature vs nurture, that been going on for decades arguing between what determines one’s character traits. I believe a person's upbringing (nurture) determines their character, rather than the person being born with it (nature). What is nurture? Nurture refers to human traits one gets from the environment that they grew up in. Has anyone heard of the phrase "fear of the unknown"?
Scientists and the general population favor genetic engineering because of the effects it has for the future generation; the advanced technology has helped our society to freely perform any improvements. Genetic engineering is currently an effective yet dangerous way to make this statement tangible. Though it may sound easy and harmless to change one’s genetic code, the conflicts do not only involve the scientific possibilities but also the human morals and ethics. When the scientists first used mice to practice this experiment, they “improved learning and memory” but showed an “increased sensitivity to pain.” The experiment has proven that while the result are favorable, there is a low percentage of success rate. Therefore, scientists have concluded that the resources they currently own will not allow an approval from the society to continually code new genes. While coding a new set of genes for people may be a benefitting idea, some people oppose this idea.
