The Advantages And Disadvantages Of Cloning
Since the cloning of Dolly the sheep in 1996, cloning has become something of a buzzword, especially in scientific circles. Formerly a staple of science fiction stories, it entered the public consciousness as it never had before. Not surprisingly it has generated controversy, with many of the objections coming religious organizations. Ethical implications aside however, there are however, advantages and disadvantages to the practice of cloning. Those listed below are just a few of the many pros and cons associated with cloning.

Advantages of Cloning
1/Potential benefits to modern medicine
Even today, the full potential of stem cells has not been fully explored. The issue of stem cells has led to controversy because embryos are generally used and they have to be destroyed for the cells to be used. However, a number of researchers believe thatstem cells will eventually change the face of medicine as we know it. Given the fact that the cells can be manipulated to mimic other types of cells, this can provide new ways to treat diseases like cancer and Alzheimer’s.
Cloning also offers hope to persons needing organ transplants. People requiring organ transplants to survive an illness often wait years for a suitable donor. In many cases these patients die waiting, as there are long lists of people requiring organs. Theoretically,cloning could eliminate this by producing more animals that can act as suitable donors. Pig livers have been successfully transplanted to human beings, as an interim measure until a human liver is found. Additionally,cloning of these animals not put a burden on the world’s food supply.
2/Helping infertile couples
Cloning offers couples dealing with fertility the chance to have a child of their own. Many infertile couples can’t be helped by the techniques currently available. In fact, although some states have already banned human cloning because of ethical issues, more couples struggling to have children are starting to consider the possibilities that cloning offer.

3/Reverse the aging process
Cloning is being touted as a future answer to reverse the effects of aging.The antiaging market is a prime target becuase it is alreay a multibillion industry.
4/Protecting Endangered Species
Despite the best efforts of conservationists worldwide, some species are nearing extinction. The successful cloning of Dolly represents the first step in protecting endangered wildlife.
5/ Improving food supply
Cloning could provide a means of cultivating plants that are stronger and more resistant to diseases, while producing more. The same could happen to livestock as well where diseases such as foot and mouth disease could be eradicated.Cloning could therefore effectively solve the world’s food problem and minimize or possible eadicate starvation.
Disadvantages of Cloning
1/The Element of Uncertainty
While the cloning of Dolly was seen as a success story, many embryos were destroyed before the desired result was achieved. The process started with 277 eggs, and Dolly was the single successful outcome. Regardless of success in other areas, the field ofcloning still has a long way to go. Infertile couples for example, could go through the same heartache as they would if in vitro fertilization failed.
2/Inheriting diseases
Cloning creates a copy of the original. A human clone would therefore inherit the genetic traits of its predecessor. This includes genetic abnormalities and diseases. Dolly the sheep for example exhibited signs of what some suggested were premature aging, although this was firmly denied by her ‘developers’.
3/The Potential for Abuse
If human cloning became a reality what checks and balances would be put in place to prevent abuse? Would scientists go overboard with the technology? If a couple has a clone that they are not happy with, what would they do next? These are all questions that must be raised in any discussion oncloning. Some have expressed the view that clones could be grown in a farm-like fashion simply for harvesting organs or stem cells. The potential for devaluing human life cannot be ignored.

Athletes who would like to give themselves an advantage competing physically most commonly use it (Foschi, 458). This procedure can be achieved in two different ways. One can ask to have his or her own blood injected or can request the use of the blood of a matching donor. These processes are respectively called autologous and monologous transfusions. The red blood cells are usually removed over an extended period of time. The withdrawn blood is then refrigerated for preservation and finally......

However, technology won’t stop here, but develop further. As technology develops, there are not only advantages, but disadvantages from them. A few advantages of upgraded technology are that one can save time and money and life will be made easier as a result of not having to do all the hard labor. In contrast, the disadvantages of upgraded technology are that people will loose their jobs to machines that will do the work for them. In addition, machines and robots are too complex for most people to use. I personally would want a developed world with advanced technologies. The following are the reasons why I do want a more advanced world with advanced technologies. My major reason is because when you have advanced technologies, life is much easier as robots and machines would take over your daily life chores. For example, daily life chores might be serving your breakfast, cutting your lawn, or cleaning your room. With robots and machines doing one’s chores one has time to relax. Another reason is because unlike humans, robots and machines do not make mistakes when programmed correctly. They always accomplish tasks perfectly so you won’t have to worry about making a mistake and getting trouble. Other reasons why I want......

Let us talk about this controversial topic in two important points. First of all, our everyday life has known a very remarkable development in fact the use of computers technologies became indispensable.

But it renders the human factor less creative, more dependents and it is not friable one hundred per cent.

Disadvantages of Cloning

...Rashad Jones Period 5 5-19-11 Disadvantages of Cloning Some people might ask the question, what is cloning? Cloning is the creation of an organism that is an exact genetic copy of another. Some people have there reasons for believing that cloning is the right thing to do. Others have there reasons for believing that cloning should not be allowed. I am one of the people that believe cloning shouldn’t be allowed. There are a lot of good reasons why cloning should be allowed. However, the reasons why cloning should not be allowed are more important. Let’s get into more detail. One reason I disagree with cloning is the uncertainty of science technology. It has been said that science and technology cannot solve everything. Scientist cannot even promise that the results of cloning are controllable. Some people believe that human cloning should be banned because they have potential in damaging humans’ future. Also, the cloning of Dolly resulted in the death of many embryos and newborns before success was achieved. With human cloning, even if the human clone survived, it is not guaranteed that it would develop normally. Cloning could also be the cause of losing the diversity of genes. The diversity of genes comes from parents having different sets of genes. If two people have identical genes, it can weaken our power, which makes getting certain diseases easier. So if someone has a baby by a clone, it could possibly harm the clone. Cloning could also cause diseases......

Advantages and Disadvantages of Pursing an Mba

...Advantages and Disadvantages of Pursuing an MBA Advantages and Disadvantages of Pursing an MBA The decision to pursue a Master’s in Business Administration is a difficult, personal decision. In fact, I categorize it as a life changing decision. For instance, this decision is like most major decisions people make. Whether the decision is over buying a home, changing careers, starting a family or buying that dream car, it is usually laced with advantages and disadvantages, pros and cons, and benefits and consequences. Whether or not those advantages and disadvantages are tangible, quantifiable and measurable, most would agree that they exist and they sometimes have life changing affects. For example, some people think that it is a disadvantage to buy a home because it usually results in one securing a long-term loan whereby a monetary commitment is required from the borrower or homeowner. If this commitment is broken or one is unable to pay as agreed, the borrower or homeowner can lose valuable assets, seriously hinder their ability to borrow money in the future and be looked upon by the banking and financial community as a liability or risk. On the other hand, or some of the advantages of buying a home may result in credit worthiness, proves that you are trustworthy, disciplined and according to Weintrub (2010), “gives one a sense of pride in ownership, stability and security” (para. 2.).
