Recommended: Human cloning should be banned

Mankind has always been fascinated with science-fiction idea of cloning, hoping to create copies of living organisms for medicine, or research, or personal gain. This idea, now closer to reality than science-fiction, has caused much debate worldwide. The unresolved question still lingers: Should human cloning be allowed? There are various views on the issue, but I believe that the cloning of humans, for any purpose, should not be permitted for multiple reasons.

First, cloning reduces genetic diversity. Genetic diversity is the number of different genetic combinations that are available in a given gene pool. Evolution is based on the mixing and matching of genes, which are keeping the gene pool alive. In humans, through natural reproduction, a new being is created with a mix of genes from both of its parents. With cloning, one person's DNA is taken and used to create new life. There is no crossing over between the parents' chromosomes, and the clone turns out genetically identical to its original. If this was to happen on a large scale, and everyone began to have similar genes, we could be prone to many diseases and health risks. There are many genetic combinations available for humans, and we have a high genetic diversity right now. If our genetic diversity is lowered, due to the lack of mixing genes in cloning, our disease resistance as a whole will decrease. The human race could be weakened and could suffer from many problems.

Second, cloning is dangerous and poses many health risks. People claim that it will lead to medical miracles and cures, but as of now cloning has an extremely high failure rate and has not yet been proven to be effective in treating anything. 95 to 99 percent of cloned organisms die before ...

... adopted as a baby, the parents have the ability to raise the child just like they would raise their own. While the child may not have the same genetic make-up as his or her parents, he or she would develop similar traits just by the way he or she is raised. Another option would be to use donor gametes or other options offered to infertile couples. There are options outside of cloning to provide childless parents with children.

Just because science gives man the ability to do something does not mean it should be done. Cloning tampers with the natural way of life, and causes more problems than it has solved. Many countries, including France, Germany, and Switzerland, have already banned human cloning, and other countries are in debate over the issue. The issue may never be resolved completely, but I believe human cloning should not be allowed at all.

The Opposition to Human Cloning: How Morality and Ethics Factor in
2868 Words | 6 Pages
If a random individual were asked twenty years ago if he/she believed that science could clone an animal, most would have given a weird look and responded, “Are you kidding me?” However, that once crazy idea has now become a reality, and with this reality, has come debate after debate about the ethics and morality of cloning. Yet technology has not stopped with just the cloning of animals, but now many scientists are contemplating and are trying to find successful ways to clone human individuals. This idea of human cloning has fueled debate not just in the United States, but also with countries all over the world. I believe that it is not morally and ethically right to clone humans. Even though technology is constantly advancing, it is not reasonable to believe that human cloning is morally and ethically correct, due to the killing of human embryos, the unsafe process of cloning, and the resulting consequences of having deformed clones.

The Pros And Cons Of Human Cloning
1524 Words | 4 Pages
The objective of this essay is to inform the reader(s) about human cloning. I believe that human cloning is morally wrong because one should not have the right to avoid daily responsibilities by getting someone else to handle them. There will be four sections of this paper that will be discussed. Firstly, there is an argumentative section, which will have premises along with a conclusion for an argument made against human cloning. Secondly, an explanation section, which explains how the argument against human cloning obeys the rules for a good argument. Thirdly, an objection section to where there are arguments that violates mine in order to demonstrate how objectors might object to the argument. Lastly, there will be a conclusion where I discuss

The Moral Aspect of Cloning
1369 Words | 3 Pages
Wouldn’t it be weird if a child were to grow up knowing that her mother is her sister, her grandmother is her mother, and her father was her brother-in-law? This can cause several emotional risks although this type of genetic selection may cause many sever risks. Every time her mother is to look at her, what she sees is herself growing up. There is a lot of emotional pressure on a teenager who is trying to establish his/her identity. What if everyone was to clone? What would happen to our individuality?. Cloning limits your genetic base because there are not enough individuals that would be the base of inherited material for the population. It would also stop the genetic progress since there is no combining of the genetic material and thus no opportunity to produce an animal that is superior to the parent. What if the child knows that he/she is the clone and now the identical twin of a dead sister/brother? What kind of pressure do you think that would put on the child, knowing they were made as a direct replacement for another? This child will not be the same in all ways as the other was, regardless of what the parents were hoping. One important concern is because this child will be brought up in an unusual household where unhappiness has been diverted into making a clone of the dead brother/sister instead of just adjusting to their loss. Now this child will be going through great pressures on his/her emotional...

Ethical Ethics Of Cloning
1139 Words | 3 Pages
Cloning is, and always has been an extremely contentious topic. To some, the ethical complications surrounding it, are far more promiscuous than what scientists and medical experts currently acknowledge. Cloning is a general term that refers to the process in which an organism, or discrete cells and genes, undergo genetic duplication, in order to produce an identical copy of the original biological matter. There are two main types of artificial cloning; reproductive and therapeutic, both of which present their respective benefits and constraints. This essay aims to discuss the various differences between the two processes, as well as the ethical issues associated with it.

The Ethics of Cloning Humans
720 Words | 2 Pages
The scientific arguments against human cloning were based on the results of animal trials in which mice, the infamous cloned sheep Dolly, and other mammals developed all kinds of unpredictable genetic defects. The potential represented by cloning does not automatically outweighs the risk of unseen con-sequences. There are enough people in this world without "making" more. Maybe they should be more interested in cloning needed things like food. If cloning is completely outlawed then there will probably be no hope for finding the cures for those fore-mentioned diseases.

Ethical Ethics Of Cloning
1782 Words | 4 Pages
Cloning has been a controversial topic since the time it was introduced, prompting questions of ethics. Although it has been unintentionally in use for thousands of years, it was first brought about in the 1960’s. As more and more discoveries have been gained since then, numerous uncertainties continue to be raised among scientists, politicians, and anyone interested in the issue. While the idea of cloning is intriguing and polarizing, there is a fine like that defines what is and isn’t ethical; it is moral to clone cells for research development and plants for agricultural desires, but it is in no way acceptable to clone humans and animals for reproductive reasons.

Automatically when people talk about human cloning that tend to be negative. Most reaction is people shouldn't play god or interfere with nature. Of course there are negative consequences that could come from cloning. On the other hand there is so many positive things that could save more lives than it would cost. Yes Cloning involves risky techniques that could result in premature babies and some deaths. That is why public policy needs to be changed on cloning. The medical possibilities are endless if federal money is given to research and develop cloning techniques.

Cons Of Cloning
748 Words | 2 Pages
Human cloning destroys individuality and uniqueness. “What makes people unique is the fact that we have different genes and cloning would lose these important parts of our bodies makeup.” There would be less of a variety of people and everyone would be the same. This would not only be the good qualities, but also the bad that would pass on. Since clones and the original donor will look alike and have the same DNA, it would be nearly impossible to tell the difference. Overtime, they would lose their individuality and uniqueness. For example, say a crime was committed.

“Cloning represents a very clear, powerful, and immediate example in which we are in danger of turning procreation into manufacture.” (Kass) The concept of cloning continues to evoke debate, raising extensive ethical and moral controversy. As humans delve into the fields of science and technology, cloning, although once considered infeasible, could now become a reality. Although many see this advancement as the perfect solution to our modern dilemmas, from offering a potential cure for cancer, AIDS, and other irremediable diseases, its effects are easily forgotten. Cloning, especially when concerning humans, is not the direction we must pursue in enhancing our lives. It is impossible for us to predict its effects, it exhausts monetary funds, and it harshly abases humanity.

Secondly, “the most the human race has to loose by playing around with cloning is that the genetic diversity would be lost (Andrea Castro, 2005).” Reducing the genetic differences will produce clones that are grossly overlarge, many animals will be born with genetic mutations, and there will be a higher “risk of disease transfer (Saskaschools, 2003). “A review of all the world's cloned animals suggests that every one of them is genetically and physically defective (Leake, 2002).” Mutations will be passed on to the younger generation because if a cloned species has a mutation in their DNA this mutation will be passed on. Cloning has been linked with diseases of ageing, arthritis and, cancer.

Human Cloning Should be Illegal
573 Words | 2 Pages
Human cloning is dangerous. It is estimated that between 95 and 98 percent of cloning experiments have failed (Genetics and Society). These downfalls to cloning are in the form of miscarriages and stillbirths (Genetics and Society). Cloned human beings also run the risk of having severe genetic abnormalities. Children cloned from adult DNA would, in a sense, already have “old” genes. These children’s main problem would be developing and growing old too quickly. This includes arthritis, appearance, and organ function. Since the chance of having a child with mental and physical problems is so much higher than that of a normally conceived child, cloning should be illegal.
