human cloning advantages and challenges

With the use of modern technology, man has been able to create life. Scientists have done the research and performed successful experiments that have cloned pigs, sheep, and various organs. While there is virtually no limit on cloning animals, there are vast limitations on cloning anything involved with humans.

There are people on certain sides saying that man should not be able to create another human through cloning because it goes against their religious alignment. Religion should not be able to hold humanity back in advancing to the future to help the well-being of all mankind. The cloning of human parts such as organs, tissue, muscle, etc. It should not be hindered because of its health benefits, and the cloning of humans, as a whole, should not be hindered because it is our natural right to advance as a species and learn what else we can learn about ourselves.

The era of cloning started when the sheep Dolly was fabricated in 1996 (Pattinson and Caulfield). Cloning is actually the procedure of producing a genetic copy of an organism through a technique called nuclear transplantation, which is a process of removing a nucleus. Therefore, the sheep was cloned through SCNT (somatic cell nuclear transfer) by eliminating the nucleus from other cells or a skin (mammary gland cell in Dolly’s case). The nucleus is further then injected into an egg. Then, the engineered egg is stimulated, and the embryo comes into being in asexual reproduction if cloning works. The cloning would be complete if this happened. Then, if the cloned embryo is inserted in a mother, it grows like a natural embryo during the fatal stage of birth. Numerous mammals are now regularly cloned — cattle, pigs, and mice, to name a few. Scientists found that monkeys are a difficult species to make through SCNT, and they have not succeeded in bringing a cloned monkey to birth until now.

The next step would be to clone humans. Compared with animal cloning, cloning humans has been more technically challenging. A group of scientists in many scientific journals established outcomes of embryos of a cloned human, emerging four of them for almost ten days in a dish to the blastocyst stage ( around 150-200 cells). The stage of the blastocyst is a stage in which embryos manufactured in vitro are generally inserted if they are to gestate to birth. The purpose of the recent research was not that. The process is called “therapeutic cloning” —instead, embryonic cell lines are manufactured, and cloned embryos are destroyed (Shepherd et al.). Therefore, human cloning is significant for research purposes or for birth. It is important in even medical treatments and in the search for biological knowledge.

Human cloning is better in some ways, and it can be worse as well, so it is important to learn and understand the arguments from both sides. Human cloning is quite beneficial for infertile couples to provide biological children, for couples who do not conceive a child in order to have a biological child clone themselves. It also provides for lesbian and gay couples to have a child that includes parent genes and DNA. The proper adoption of human cloning has expanded medical research in other worlds and cures many medical conditions. As a result of this, it cures most of the deadly and terminal diseases, replaces body parts and organs, and improves medicines.

Adult stem cells will be cloned to interchange destructive tissues with therapeutic cloning. With the method of human cloning, body parts are amputated from the leg and can be replaced. It can be possible to reproduce the missing body parts and attach them to the patient’s leg through surgery (Smith). It can also solve the problem of organ donation; the patient himself can give healthy tissues and cells that can be used for transplant organs and cloned. Therefore, it can ease the organ transplant waiting list.

Human cloning eradicates birth defects and lessens abortion. Genetic birth defects are sometimes inevitable, and these stop with abortion. So, human cloning provides an effective way to the unborn child diagnosed with genetic defects by cloning healthy cells and can be used to change the deserted gene of the fetus. This reduces the occurrence of pregnancies that often lead to abortions and eliminates the defective genes. Human cloning also provides older people a chance to be healthier and live longer. Regenerate the tissues and cells through stem cells with cloning. Thus, they will have healthier organs and strong immune systems. Human cloning could bring back genius, influential, and legendary people. This means that it is possible to build more Einstein and Isaac Newton, who helped to solve many problems. So that human cloning will be able to give medicine and science.

For many years, heart diseases have been so common not only in the United States but also in some other industrialized countries. However, scientists believe that the use of human cloning technology will somehow reduce heart attacks and many other heart diseases by cloning their heart cells and inserting them into the specific damaged area of the heart. The autosomal recessive genetic disorder, Tay-Sachs disease, can be prevented by cloning. Provide the clone livers and clone kidneys for liver and kidney transplants. For children and adults suffering from Leukemia, clone bone marrow can reduce the disease. Women can avoid the high risk of Down’s syndrome by cloning.

Because of the technology of human cloning, many immune diseases can be eliminated by cosmetic procedures and silicone breast implants. Doctors will be able to create fat, bone, cartilage, or connective tissues that match the tissues of patients with the new technology. Embryonic stem cells can be used to develop tissue or organs to repair damaged ones. Brain cells in the brain damaged, skin for burn victims, paraplegics, spinal cord cells for quadriplegics, livers, lungs, kidneys, and hearts could be produced. If human cloning and its technology are not banned, situations such as Parkinson’s disease, Alzheimer’s disease, heart failure, diabetes, degenerative joint disease, and many other problems may be remediable. There should be no stipulations on human cloning. Many people believe that human cloning is against morality and ethics. People claim that cloning is against God and that reproduction occurs between man and woman, not between science and humans. However, they have not given scientific proof of these statements, and it is mentioned in the religion that human cloning is not allowed. Most people would support human cloning in many conditions.

If a couple becomes infertile after the birth of their first child, they can conceive another baby by using human cloning technology regardless of the one they already have (Kass and Wilson). If parents lost their child after birth to a tragic accident, they would bring their child back, but it would be like other twins. Two parents have a baby boy with muscular dystrophy, doctors attempt approximately 20 operations to keep them mobile and healthy but the boy dies in his teenager so human cloning provides the DNA live again without having muscular dystrophy.
