The cloning of ‘Dolly’ the sheep in 1997 by Ian Wilmut and his colleagues
at the Roslin Institute in Edinburgh generated a spontaneous worldwide reaction.
Dr. Richard Seed, an American geneticist, claimed he would be able to clone
human beings within a year. A Korean doctor was reported to have created, and
killed, the first human clone, but was subsequently found to have fabricated
his results. President Clinton ordered research into the ethics of human
cloning, which subsequently became the Shapiro Report. The United States has
imposed a moratorium on human cloning and a ban on federal funding of cloning
research that will be reviewed every five years. One bill to make human cloning
lawful and another demanding its prohibition were both rejected by Congress in
1999. In Britain human therapeutic cloning is legal but requires licenses,
reproductive cloning is however illegal. Germany, Switzerland and several
American states have passed laws expressly forbidding human cloning, whereas
Canada and Ireland have no relevant legislation at present. The opposition of
international organisations towards human cloning seems clear. The European
Parliament, the Council of Europe, UNESCO and the WHO have all passed
resolutions asserting that human cloning is both morally and legally wrong.
There is a clear distinction between ‘reproductive cloning’ and ‘therapeutic
cloning’. Reproductive cloning relates to the use of the technology with the
intention to produce a foetus identical to its parent. The technique used to
produce Dolly is known as ‘nuclear transfer’, whereby the nucleus from a
somatic cell was fused with an unfertilised egg from which the nucleus had been
removed. This method of procreation is ‘asexual’, as it does not require one
person of each sex in order to produce a child. A single mother or a lesbian
couple, for example, could produce a child genetically related to them both,
without the necessity for a male gamete.

Cons

Cloning is unsafe. The technology is
unsafe. The nuclear transfer technique that produced Dolly required 277
embryos, from which only one healthy and viable sheep was produced. The other
foetuses were hideously deformed and either died or were aborted. Even today,
cloning animals through somatic cell nuclear transfer is simply inefficient.
The success rate ranges from 0.1 percent to 3 percent, which means that for
every 1000 tries, only one to 30 clones are made. Or you can look at it as
970 to 999 failures in 1000 tries.
Moreover, Ian Wilmut and other commentators have noted
that we cannot know whether clones will suffer from premature ageing as a
result of their elderly genes. Dolly the sheep herself suffered from
premature arthritis. There are also fears that the reprogramming of the
nucleus of a somatic cell in order to trigger the cell division that leads to
the cloning of an individual may result in a significantly increased risk of
cancer.
|
Cloning is in this respect no different from any other
new medical technology. Research is required on embryos in order to quantify
and reduce the risk of the procedures. Embryo research is permitted in
Britain until the fourteenth day of embryo development. Many other Western
countries are also actively engaged in embryo research. The thousands of
‘spare’ embryos generated each year by IVF procedures and destroyed could be
used to the good purpose of human cloning research. It should be noted that
cloning has come a long way since dolly in 1997. In 2008 Japanese scientists
managed to create clones from the bodies of mice which had been frozen for 16
years.
|
Playing God. Cloning is playing
God. It is not merely intervention in the body’s natural processes, but the
creation of a new and wholly unnatural process of asexual reproduction.
Clerics within the Catholic, Muslim and Jewish faiths have all expressed
their opposition to human cloning. However, this objection to cloning is not
specifically theological. David Hume, the eighteenth-century Scottish moral
philosopher, warned us to heed our feelings as much as our logical reasoning.
Leon R. Kass of the University of Chicago has stated in relation to human
cloning, that mere failure to produce scientific reasons against the
technology does not mean we should deny our strong and instinctive reactions
to it. As he states, there is a "wisdom in repugnance".
|
This argument assumes that we know God’s intentions.
Evidently, there is no biblical statement on the ethics of human cloning. Who
is to say that it is not God’s will that we clone ourselves? Hindu thought
potentially embraces IVF and other assisted reproduction technology (ART).
Moreover, every time that a doctor performs life-saving surgery or
administers drugs he is changing the destiny of the patient and could be thus
seen as usurping the role of God. Furthermore, we should be very wary of
banning something without being able to say why it is wrong. That way lie all
sorts irrational superstition, repression, fundamentalism and extremism.
|
Cloning harms families. Reproductive cloning harms the integrity of the family. Single people
will be able to produce offspring without even the physical presence of a
partner. Once born, the child will be denied the love of one parent, most
probably the father. Several theologians have recognised that a child is a
symbolic expression of the mutual love of its parents, and their hope for the
future. This sign of love is lost when a child’s life begins in a laboratory.
|
This argument is wholly unsuited to the modern age.
Society freely allows single people to reproduce sexually, whether by
accident or design. Existing lawful practices such as sperm donation allow
deliberate procreation without knowledge of the identity of the father.
Surely it is preferable for a mother to know the genetic heritage of her
offspring, rather than accept sperm from an unknown and random donor?
Moreover, reproductive cloning will allow lesbian couples to have children
genetically related to them both. It might be better for the welfare of the
child for it to be born into a happy relationship, but the high rates of
single parenthood and divorce suggest that this is not always possible.
|
Cloning violates human dignity. Reproductive cloning is contrary to human dignity.
‘Donum Vitae’, the declaration of the Catholic church in relation to the new
reproductive technologies, holds that procreation outside the conjugal union
is morally wrong. Many secular organisations, such as the WHO and UNESCO have
issued statements that similarly find cloning violates human dignity.
Assisted reproductive technologies might all be seen as challenges to human
dignity, including IVF and sperm donation. However, human cloning is a
completely artificial form of reproduction, which leaves no trace of the
dignity of human procreation.
|
When people resort to talking in wholly empty abstract
terms about ‘human dignity’ you can be sure that they have no evidence or
arguments to back up their position. It is difficult to understand why the
act of sexual intercourse that leads to sexual procreation is any more
‘dignified’ or respectable than a reasoned decision by an adult to have a
child, that is assisted by modern science. The thousands of children given
life through IVF therapy do not suffer a lack of dignity as a consequence of
their method of procreation. The Catholic church regards every embryo from
the moment of existence as a living person. This position is not shared by
most Western governments, and it would deny not only cloning, but IVF and all
the medical knowledge and benefits that have accrued from embryo research.
|
Cloning treats children as objects. Cloning treats children as objects. Children will be
manufactured by an expensive technological process that is subject to quality
control. The gulf between an artisan and an artefact is immense. Individuals
will be able to have a child for the sake of having children, or as a symbol
of status, rather than because they desire to conceive, love and raise
another human being. Cloning will not only allow, but actually encourage, the
commodification of people.
|
The decision making and the effort that will be
required to clone a human suggests that the child will be highly valued by
its parent or parents. Furthermore, we should not pretend that every child
conceived by sexual procreation is born to wholly well-intentioned parents.
The desire to have ‘a son and heir’ is common around the world but does not
concern the welfare of the future child. Similarly, children are often
conceived out of marital custom, in order to consolidate a relationship, or
even in order to gain free accommodation from local housing authorities.
Finally, many children are not intended at all, but are born as a result of
unplanned pregnancies. There would be no fear of ‘accidental cloning’ that could
bring a child to a parent who was unprepared, or unwilling, to love it.
|
Cloning will lead to a lack of diversity amongst the
human population as it is creating genetic copies rather than increasing
diversity by mixing genes. The natural process of evolution will be halted,
and as such humankind will be denied development, and may be rendered more
susceptible to disease.
|
Will allow the elimination of diseases. Cloning is unlikely to be widespread so any dangers
from any reduction in the diversity of the human gene pool will be so limited
as to be virtually non-existent. The expense and time necessary for
successful human cloning should mean that it will only be used to the benefit
of the small minority of people who require the technology. The pleasure of
procreation through sexual intercourse does not suggest that whole
populations will prefer to reproduce asexually through cloning. The only
significant lack of diversity which can be expected will be in women who
suffer from a severe mitochondrial disease. They will be able to use cloning
by nuclear transfer in order to avoid passing on the disease which is carried
in their egg cells to any offspring. This elimination of harmful genetic
traits from the gene pool is no different from the eradication of infectious
disease, such as small pox, and should be welcomed. So against these very
marginal worries there is potentially great good to be done through cloning.
Currently already we have IVF and genetic screening which can prevent that
babies with certain diseases are born. In 2000 the baby Adam Nash was born,
genetically manipulated through IVF, as a genetic fit to cure his sister
Molly from Fanconi anemia. While this was not cloning it gives an idea what
cloning could possibly cure. It could be a way of curing siblings from
chronic diseases and also ensuring that the transplants (for example) will
not be rejected due to genetic differences.
|
Cloning will lead to eugenics, or the artificial
manipulation and control of the characteristics of people. An American
geneticist, Dr. Dan Brock, has already identified a trend towards ‘new and
benign eugenics’ that is perpetrated by developments in biotechnology. This
can particularly be seen on a small scale with ‘designer babies’. When people
are able to clone themselves they will be able to choose which type of person
shall be born. This seems uncomfortably close to the Nazi concept of breeding
a race of Aryan superhumans, whilst eliminating those individuals whose
characteristics they considered unhealthy. The ‘Boys from Brazil’ scenario of
clones of Hitler, the baby farms of ‘Brave New World’, or even the cloning or
armies of identical and disposable soldiers, might soon be a very real
prospect.
|
Clones will still be individuals. There is much more danger of eugenics associated with
developments in gene therapy and genetic testing and screening, rather than
human cloning. The notion of clones of Hitler is frankly preposterous.
Psychologists have shown that nurture is at least as important as genes in
determining personality. It would be impossible to produce another Hitler, or
Elvis, or whomever, by cloning or any other ART. Clones (people with
identical genes) would by no means be identical in every respect. You only
need to look at identical twins (who are genetic clones of each other) to see
how wrong that assumption is, and how different the personalities,
preferences, and skills of people with identical genes can be. The idea of
breeding huge fighting forces is also confined to the realm of science
fiction. The necessity of thousands of willing mothers, the nine month
gestation process, and the many years rearing this child towards adulthood,
means that cloning would hardly be an efficient technique for any mad
dictator to raise an army. And there is no reason, in any case, to suppose
that a clone would be any more willing or effective a soldier than any other
human being - clones (like twins) are just as conscious and free as everyone
else.
|
Human reproductive cloning is unnecessary. The
development of in vitro fertilisation and the practice of sperm donation
allows heterosexual couples to reproduce where one partner is sterile.
Moreover, merely 300 babies are adopted each year in the United Kingdom. It
might be better for potential parents to give their love to existing babies
rather than attempt to bring their own offspring into an already crowded
world.
|
Cloning should be allowed for those who can’t otherwise
have a child. The desire to have
one’s own child and to nurture it is wholly natural. The longing for a child
genetically related to oneself existed long before biotechnology, but it is
only recently that medicine has been able to satisfy it. In vitro
fertilisation remains an imperfect technology. Couples typically submit to
four cycles of costly treatment before producing a child as the chances of
having a child can be as low as 10%. Evidently, the technique does not assist
homosexual couples, couples where both partners lack gametes, or where the
female partner suffers from a mitochondrial disease. Cloning would allow a
child to be born to all these couples.
