Is cloning animals ethical?
Cloning animals is ethical, cloned animals live healthy and happy lives. Cloned animals live slightly shorter lives. Should cloned animals be cloned for meat? So what are clones? Clones are exact genetic copies of a DNA donor. Clones look exactly like the DNA donors.
Cloned animals have small health problems. Clones have larger organs than normal animals. Which can lead to breathing problems. Many clones die young. The first clone, Dolly the Sheep died of water in her lungs. This is not always the case for cloned animals. Many clones live healthy lives without lung and health problems.
Cloned animals don’t always live long but should the meat of clones be eaten. “Meat and milk from cloned cattle, pigs and goats, and their offspring, is as safe to eat as meat from non-cloned animals,” says the Federal Drug Administration. If the meat is healthy why not eat it. Well, more than fifty-percent of people in the United States of America. I know that if I needed to eat cloned meat I would. I would also eat the dairy and milk from cloned animals.
So cloned meat is a healthy source of meat but do cloned animals live healthy lives? Yes, cloned animals live healthy lives despite having larger organs than usual. Clones are born from surrogate mothers. That means the DNA is inserted into a

different mother which is a little strange. The births are healthy for both the mother and the many children. Birth is the most important part of a clone's life. What are the problems of cloning?
Cloning has a very and I mean very low percentage of success. “The success rate ranges from 0.1 percent to 3 percent, which means that for every 1000 tries,” says the Genetics Department at Utah University. Think about it this way, for every 1,000 attempts at cloning an animal 1 to 30 clones are made. The first clone, Dolly the Sheep took more than two-hundred and fifty tries. Dolly the Sheep was not technically the first clone on July 5th 1996 but was the first to reach adult hood, the first clone was actually created in the Nineteen-Fifties, they were tadpoles that did not turn into
frogs. How many animals have been cloned? Twenty-animals different species have been cloned. Most of the twenty have mammals. Many subspecies of cattle have been cloned in the United States of America. This is incredible, in the Spring of 1999 a group of Spanish biologist cloned an extinct animal name Celia the Pyrenean ibex. Celia sadly passed away after only 7 minutes of life. The scientists were able to take samples of blood. In fact Celia’s body is on display in Spain. This brought hope to the scientific community that bringing extinct animals back to life is possible. In fact, many efforts have been exerted to bring back the life of a baby Wooly Mammoth. The Mammoth was found buried in ice in Russia. Is cloning animals healthy, ethical, safe, interesting, you tell me?
Even though natural born animals present a higher survival rate, cloned sheep and cows show different results. Even if the cloned cows and sheep show a positive sign of survival, most of the cloned animals’ die either in the womb or after the clone exits the womb. (Anthes 63). Through this example, death dominates the choices of these cloned animals, and scientists continue the experiments for the benefits of humans. By focusing on human needs, the scientists pretend that animal welfare means absolutely nothing, but animals deserve safety just like humans. If scientists truly believe that cloning meets moral standards, than how come scientists cannot find a more effective way to decrease the failure rate of
Cloning has been in nature for thousands of years, a clone is a living thing made from another consisting of the same DNA. For example identical twins are clones because they have the same DNA but the differ because the twins begin after conception when a zygote, a totipotent stem cell, divides into two, some plants self-pollinate and produce a seed, which in turn, makes plants with the same genetic code (Hyde). According to the Human Genome Project there are three types of cloning, DNA, therapeutic and reproductive; DNA cloning involves transferring DNA from a donor to another organism, therapeutic cloning, known as embryo cloning, involves harvesting stem cells from human embryos to grow new organs for transplant, and last is reproductive cloning which creates a copy of the host (Conger). One of the earliest cloned animals was a sea urchin by Hans Dreisch in the late 1800’s. Unlike Victor Frankenstein, Dreisch’s goal was to prove that genetic material is not lost in cell division, not to create another being, (History of Cloning) stated by Frankenstein “that I might infuse a spark of being into the lifeless thing that lay at my feet.” There are many ways an animal...
Human cloning research has once been the subject of terrifying science-fiction films and novels, science experiments gone wrong, accomplished only by the evil scientists twirling their moustaches. However, ideas presented on page and screen are rarely accurate. The possibility of cloning an exact copy of another human with one already fully developed is almost impossible, but through meticulous research, scientists have discovered the numerous benefits of cloning humans, either with individual cells or an embryo.
successful clones often have problems with their body and are subject to a short lifespan ridden with health problems. This hurts the person or animal cloned rather than to help them, making cloning an immoral
This is explained by Craig Freudenrich. He discusses this on the website HowStuffWorks. Freudenrich tells of how Ian Wilmut and his colleagues successfully cloned Dolly the sheep at the Roslin Institute in Midlothian, Scotland. Dolly the sheep was the world's first successfully cloned mammal, cloned from an adult somatic cell. He writes how after Dolly, scientist have been cloning animals like cows and mice. “They rely on transplanting the genetic information from a specialized cell into an unfertilized egg cell, whose genetic information has been destroyed or physically removed.” (How Cloning Works) This information is very enlightening to anyone who questions how cloning works. Furthermore it secures the information needed to inform the general public of what they need to know to have a responsible and appropriate
In recent decades, questions about genetic engineering, genetic modification, and cloning of animals and humans are on the minds of many. On February 27, 1997 when Dr. Ian Wilmut and his team sent chills down our spine with the announcement of the first successfully cloned sheep Dolly. At this time the reality of animal cloning stared us in the face while the human cloning was just around the corner.
Cloning is a topic with complexities that should be taken into consideration before one simply agrees or disagrees with it. There needs to be ethical codes set to ensure that the beneficial attributes of this method, such as crop propagation and cell research, can be taken advantage of, and so the unethical concepts, such as human and animal cloning for reproduction, can be banned. Imagine the improvements of life that are possible in the near future for society with a moral stance taken on this matter; the possibilities for millions are indescribable.
Imagine a world where everyone looked like you and was related to you as a sibling, cousin, or any form of relation, wouldn’t that be freaky? Although cloning is not an important issue presently, it could potentially replace sexual reproduction as our method of producing children. Cloning is a dangerous possibility because it could lead to an over-emphasis on the importance of the genotype, no guaranteed live births, and present risks to both the cloned child and surrogate mother. It also violates the biological parent-child relationship and can cause the destruction of the normal structure of a family. The cloning of the deceased is another problem with cloning because it displays the inability of the parents to accept the child’s death and does not ensure a successful procedure. Along with the risks, there are benefits to Human Reproductive Cloning. It allows couples who cannot have a baby otherwise to enjoy parenthood and have a child who is directly related to them. It also limits the risk of transmitting genetic diseases to the cloned child and the risk of genetic defects in the cloned child. Although the government has banned Human Reproductive Cloning, the issue will eventually come to the surface and force us to consider the 1st commandment of God, all men are equal in the eyes of god, but does this also include clones? That is the question that we must answer in the near future in order to resolve a controversy that has plagued us for many years.
There are many physical harms caused by cloning. Some of these harms include an array of illnesses that come along with cloning. Another one of the harms is waste. This may seem like a strange way to say it, but the fact of the matter is that many of the embryos being cloned today are being killed and therefor, wasted. According to the Council on Ethical and Judicial Affairs of the American Medical Association, “There have been countless demises among amphibians, lambs, and mice.” (ama-assn.org). Another source says that this is also true about human embryos. Dr. Elizabeth Mitchell states in her article, Human Clones: Created to Die, that, “Human beings, even IVF (in vitro...
Although the clones are genetically identical, this does not mean that they will act, or look the same as the organism from which they were cloned. “Anyone who thinks they might be able to get Spot or Fluffy back is mistaken. Cloned animals have distinct personalities, just like identical twins”, said Robert Lanza who has both successfully and unsuccessfully cloned several animals (Singer). In most cases, the clone will act different than the organism from which it was cloned because animals, including humans, are products of their environment. If a pet was abused as a baby, they will likely act timid and afraid when around people similar to their abuser for the rest of their lives, but the clone would not know to act this way because they were never abused themselves. Another example could be cats; the clone of your old pet cat may be larger than the old one, because it was fed more or does not exercise as much. Also, the cats may have different hair colors as well because their genes for hair color can randomly switch on and off. In a recen...
First of all, “Australia’s first cloned sheep appeared to be healthy and energetic the day she died, during the autopsy they could not find the cause (Castro, 2005).” There are many risks to cloning and you are seldom able to identify the cause of their death. “More than 90% of cloning attempts fail (Human Genome Program, 2006).” Most cloned animals died mysteriously even before they were born or when they were very young, so there is hardly any information on how clones age. Clones may be born with a normal looking body but may have internal functioning problems. “Cloned animals tend to have more compromised immune function and higher rates of infection, tumor growth, and other disorders (Human Genome Program, 2006).” There are many risks of cloning and a major factor is genetic differences.
been made possible but yet a majority of them have died in early stages of development or after birth according to the study of the cloned sheep, Dolly (Magalhães 1). Those who make it suffer from several defects acquired from birth (Magalhães 1). During recent experimentation it took scientist Ian Wilmut of the Roslin Institute in Edinburgh, Scotland, and his colleagues who created Dolly (a cloned sheep) 277 tries before they got a healthy, feasible lamb (Human Cloning 1). Due to the complication of human cloning even more deaths and deadly birth defects can be expected (Human Cloning 1). Even though human cloning has never been performed, one likely possibility is that babies born through this process will as well feature lethal birth defects (Magalhães 1).
A cloned pet can never be the same as the original because of different upbringing, environment and experiences. Trying to continue where you stopped with the dead pet may be hard for the owner and so a replica of the pet may only give solace to the grieving owner. Hillary says it’s immoral to clone pets and try to take advantage of grieving owners. Pet cloning also causes great harm to animals. The animal being cloned is more likely to have defects than the original animal.
While cloned animals should not be used for food, cloned animals should be used as food because it will be able to rapidly reproduce animals and multiply the amount of food; as well using cloned animals will be beneficial to many people and
This dialogue is between two students at the university. Steve is a little uncomfortable about cloning, while Sally presents many valid arguments in favor of it. Steve presents many moral questions that Sally answers.
