Several states have also established restrictions on human cloning; one
state has even banned human cloning. These government actions are irrational
and should be immediately revoked. The federal government should regulate,
not ban, human cloning. This is because significant benefits can result
from cloning technology. The ethical implications are also only temporary.
They are induced by misconception. Besides, fanatic biologists are going
to pursue human cloning technology with or without government consent.
It would be beneficial if I begin by briefly explaining the history of
cloning and the processes involved. Dolly was given birth in Febuary 1997.
She was created by Ian Wilmut and his colleagues at Roslin Institute in Scotland.
She was created using a technique called “somatic-cell nuclear transfer”.
This is where a nucleus-omitted ovum is injected by a nucleus
taken from a body cell. A jolt of electricity allows the reconstructed
egg to divide. The egg is then inserted into a uterus to develop.
This is the way the first human clone will mostly likely be made.
Numerous of remarkable benefits can come from cloning technology.
One of these is a treatment for infertility. Infertility is caused by
genetic defects, injuries to the reproductive organs, congential defects and
exposure to toxic substances and radiation. Many assisted-reproduction
technologies have been developed. This includes surrogate mothers for
women without a functional uterus, intracytoplasmic sperm injection for males
who can’t produce viable sperm, and IVF for women with blocked or missing fallopian
tubes. However, these treatments have proven to be highly inefficient
and they can’t help people whose reproductive organs have not developed or have
been removed. Twelve million Americans are infertile at child
bearing age. They will pursue years of painful and expensive treatments
to have little chance of success. Human cloning can offer infertile people
a higher chance of success. Most people are infertile because they can’t
produce viable gametes. Cloning technology wouldn’t require viable sperm
or egg, any body cell would do. This technology would be able to bypass
defective gametes and allow infertile people to have their own biological children.
Cloning technology may even prevent clinical depression, divorce, and suicide
among infertile people. This is because infertility often leads to them.
Cloning technology can help “perfect” gene therapy, the actual correction
or replacement of defective gene sequences. Gene therapy is currently
limited because of inefficient vectors, or viruses that convey new genes into
cells. A copy of a defective gene is in every cell of the body.
These viruses must infect everyone of these cells and replace the defective
genes with the normal genes. However, these vectors only infect a frustrating
small amount of cells. This deems gene therapy inefficient. Human
cloning can change this. Scientists can determine which cells recieved
the desired gene alteration using fluorescent tages; the cells that were affected
would glow. Cloning technology would allow scientists to take a cell that
had it’s genome modified and use it to produce an offspring. The resulting
child and its descendants would carry the corrected gene in every cell.
Cloning technology may be able cure Tay-Sachs disease, cystic fibrosis, muscular
dystrophy, and Huntington’s disease.
Another benefit of human cloning is that it will allow scientists to better
understand cell differentiation. Research on the basic processes of cell
differentiation can lead to dramatic new medical interventions. Cell differentiation
is where a stem cell, found inside embryos during the first two weeks of development,
specializes into cells that perform specific functions. These cells have
the potential to develop into any type of cell in the human body. Biologists
do not know which internal/external factors induces a stem cell to develop into
a specialized cell, whether it be a muscle cell or a nerve cell. A better
understanding of cell differentiation will allow biologists to transform stem
cell into which ever cell that he/she desires. Burn and spinal cord injury
victims might be provided with artificially produced replacement tissues.
Damage done by degenerative disorders like diabetes, Parkinson’s disease or
Alzheimer’s disease might be reversed. Biologists might be able to create
organs for transplant using merely a dead skin cell.
Ethical implications involved in human cloning is only temporary.
This can be shown in the development of In Vitro Fertilization(IVF).
During the 1960s & 1970s, oponents of IVF argued that it was unsafe, children
would be deformed, American families would be destroyed or changed, and it was
against God’s will. These are the same arguments being used against human
cloning. Eighty-five percent of Americans thought IVF should be outlawed
during the 1970s. Public opinion changed when they saw Louie Brown, the
first child born using IVF. People noticed that he was just a child. Their
fears of IVF subsided. It became a routine medical procedure within a
few years. This will most likely be the case with human cloning.
Many of the ethical arguments against human cloning are induced by misconception.
The “Mini-Hitler” scenario I’ve listed above is far-fetched, but that is exactly
the kind of thing people think about when they hear the word “cloning”.
People think that cloning technology can
produce an exact copy of an existing adult human being. This isn’t true.
Cloning technology can only produce a cloned embryo. The embryo must develop
in a uterus. The developed child must experience childhood and adolescence.
People think that a clone will be both behaviorally and physically identical
to its donor. This also isn’t true. The clone will probably be identical
physically, but not behaviorally. Genes contribute to the array of our
abilities and limits, but our behavior and mentality is constantly shaped by
enviromental factors. Even identical twins show differences in behavioral
and mental characteristics. Someone trying to clone a future Adolf Hitler
might instead produce a modestly talented painter.
Ethicists are afraid that a subordinate class of humans will be created
as tissue and organ donors. They are afraid that the rights of these clones
will be violated. These fears are outrageous and ridiculous. These
ethicists have been the victims of misconception. Cloned humans could
no more be “harvested” for their organs than people can be today.
Another ethical dillemma is the psychological well-being of the cloned
child. People wonder what kind of a relationship a cloned child will have
with his/her parent that is physically identical. They are curious of
how the child will deal with the pressure of constantly being compared to an
esteemed or beloved person who has already lived. We need to remember
that the single most important factor affecting the quality of a child’s life
is the love and devotion he/she recieves from parents, not the methods or circumstances
of the person’s birth. Since children produced by cloning will probably
be extremely wanted children, there is no reason to think that with good counseling
support for their parents they will not experience the love and care they deserve.
What will life be like for the first generation of cloned children? Being
at the center of scientific and popular attention will not be easy for them.
They and their parents will also have to negotiate the worrisome problems created
by genetic identity and unavoidable expectations. However, there may also
be some novel satisfactions. As cross-generational twins, a cloned child
and his/her parent may experience some of the unique intimacy now shared by
sibling twins.
Animal research will eventually indicate that human cloning can be done
at no greater physical risk to the child than IVF posed when it was first introduced.
It would be better if such research would be done openly in the U.S., Canada,
Europe or Japan. Established government agencies could provide careful
oversight of the implications of the studies for human subjects. The most
probable way that it will happen will be, if not yet already, in a clandestine
fashion. A couple desperate for a child will put their hopes in the hands
of a researcher seeking fame. Advanced Cell Technologies(ACT) has already
created the first human embryo. They took DNA from a man’s leg and injected
it into a cow’s egg with its nucleus removed. There has also been reports of
similar work in South Korea. Someone is going to clone a human with or
without government assistence. It would be beneficial if our federal government
regulated such experiements, rather than outlaw them. Outlawing something
will not neccessarily stop it from happening. Regulating human cloning
will allow our federal government to closely overlook experiments pertaining
to human cloning.
The federal government should regulate human cloning. Banning it
would deprieve many beneficial treatments from people who need it. I have
mentioned only a few of cloning technology’s significant benefits. Cloning
technology can lead to a better understanding of cell differentiation.
This would allow biologist to produce tissues and organs for transplant.
Cloning can help carriers of genetic defects to have healthy children.
It can even help to completely eradicate genetic mutations and defects.
Treatment of infertility is one of its most promising benefits. Cloning
technology can help infertile people to have their own children, one of life’s
most powerful biological drives. Besides, ethical implications involved
in human cloning are only temporary. They are induced by misconception.
Education will change people’s negative attitude towards human cloning.
If we give human cloning a chance, it will most likely become a part of our
daily lives.
