The Vast Potential of Human Cloning

Think of a world where infertile, childless couples can go to a medical clinic, purchase cell replacements for malfunctioning cells in the reproductive system and, thus, bear kids; a world where people afflicted with degenerative diseases like Parkinson's and Alzheimer's Disease can replace their damaged cells and be cured again; a world where the crippled can get the much-needed cells to revive their spinal chord and walk again.

Those amazing medical and scientific feats are only the tip of the iceberg when the potential of human cloning is concerned. Developed to its extreme, human cloning can make disease and sickness, maybe even physical suffering altogether, a thing of the past.

There are two basic kinds of human cloning and, separately, each offers us a deeper insight as to the vast possibilities of this burgeoning new science. In reproductive cloning, a cloned embryo is implanted in a woman's uterus from where, theoretically, a normal baby develops that is genetically identical to the DNA donor. The second type of cloning, therapeutic cloning aims to provide replacement organs or tissue for people. The cloned embryo contains DNA taken from the transplant patient to ensure that the cloned organs are compatible with the person's immune system.

In the past decade, human cloning has taken great strides. To many, the biggest and most visible accomplishment in this arena was the successful cloning of two mammals: Dolly the Sheep in 1996 and Snuppy the dog in 2005. After six years, Dolly died in 2003 from non-cloning related conditions. Meanwhile, Snuppy, Time magazine's "Invention of the Year" in 2005, is alive and well.

In 2004 and 2005, Korean scientist Hwang Woo Suk, who headed the team that created Snuppy, shocked the science world when he announced that he had successfully cloned human embryos in his laboratory in Seoul. However, it was discovered that Hwang had fabricated evidence to back his scientific research. Following a thorough investigation, through, a panel of scientists pronounced that Snuppy was a legitimate clone and this achievement stands.

Ethical Aspects of Human Cloning

The Birth of Dolly (a cloned sheep) opened the door for widespread speculation regarding human cloning. Public opinion was faced with a vision of the future when human cloning is not science fiction but a fact of life. Should we be embracing this scenario with its possible benefits as a remedy to old ills? Or maybe we should be wary of the future when producing children genetically identical to the cells of a donor and creating embryos for research or therapeutic purposes is just one of the industries regulated only by economic factors?

Fact that many people react with mistrust and anxiety when confronted with such a scenario may indicate the presence of moral intuition that can't be easily ignored. Considering the issue from scientific point of view, resistance to cloning is ill - founded and pathological. Concerns about potential damages to society and individuals are dismissed by scientists prioritizing freedom of research and scientific progress. They insist on a division between science and ethics as a way of assuring the continuity of this progress.

Both types of cloning (therapeutic and reproductive) can involve creating of human embryos that are later destroyed. There are three methods of creating embryos and the differences between them are important from an ethical point of view.

The technique involved in processing stem cells taken from embryos results in production of tissues and organs genetically identical to the donor of the cells. Whereas transfer of a nucleus and embryo splitting leads to creation of genetically identical person.

Public debate on human cloning must necessarily address the issue of the status of an embryo. Some argue that since embryos contain everything needed for its development into a human, it deserves a full moral status and any procedure leading to destruction of an embryo should have the same ethical significance as a murder. Creating embryos for research is morally wrong because it expresses lack of respect for human life.

According to opponents, because an embryo lacks conscious awareness it can be only of human origin, not a human yet and although respect is due, using it for research is fully justified.

Reaching a compromise on the issue seems very unlikely considering cultural (religious) and historical circumstances. In spite of that, certain solutions are being discussed. One of them postulates to acknowledge human life as a 'religion of humanity', giving it a superior value in a moral and social order. Since cloning doesn't recognize the unique value of human life, it possesses a threat to individuals and society as a whole.

There are also opinions that our responsibility toward future generations should be sufficient reason to abandon human cloning. We are entrusted with the protection of the human gene pool, and we are expected to pass it unaltered to future generations as human heritage. Genetic uniqueness (leaving aside identical twins) supports an idea of the superiority of human life and ensures that a social order is maintained.

In an attempt to find a common ground on the issue, Unesco acknowledges all the difficulties and concerns raised and offers alternative approach to the problem. The right of the individual to autonomy and self - determination should be (according to the organization) modified by the common good of society. However, whilst cloning can be beneficial in addressing infertility problems or giving hope to those who suffer from incurable diseases, it does more harm than good to society undermining the status of human life and its superior position in the social structure.
