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
