The Effects of Genetic Engineering





Some scientists involved in the field of genetic research have been moving toward
the goal of being able to change DNA. To some people, this is the chance for a better and
healthier life, but there are other peopl
e fear that it is "playing God" and
trying to "program" a human being. Each of these views is right in certain
ways. Genetic engineering could be used to enhance people’s lives, but it could also be
used to harm people’s lives.





If
future research produces more effective and accurate processes to manipulate
human DNA, scientists will be able to create cures for diseases that are not curable today.
Even birth defects could be almost totally eliminated if doctors were able to change a
child’s genes before birth. The process could also be adapted to cure hereditary diseases
and prevent them from passing to future generations. It could also allow people with
family histories of diseases, such as cancer, to "fix" their genetic
pr
edisposition to the disease.





Another way that genetic engineering could affect our lives is its application to
plants and animals used for food. If farmers breed plants and animals specifically
engineered to produce more meat or fruit, faster and easie
r than normal, then food would
become cheaper and more plentiful. In addition, genetic engineering might allow the
creation of better tasting, or more nutritious foods.





Genetic engineering can also be applied in the fight against diseases. Through
gene
tic engineering, people could maintain their lifestyles without the threat of AIDS or


cancer. People of the world would not have to live in fear of contracting a deadly virus
or hereditary disease. In theory, genetic engineering can accomplish this. Genet
ic
engineering can improve the health of society tremendously then as it is known today.
Today genetic engineering is used in the fight against problems such as cystic fibrosis,
the "bubble boy" disease, diabetes, and several more. Cystic fibrosi
s is the
leading hereditary cause of death among Caucasian Americans, affecting one in every
two thousand children and young adults. Another deadly disease now being treated by
genetic engineering is the "bubble boy" disease. This disease is char
acterized
by a gene mutation that causes a deficiency in ADA, which causes the cells of the
immune system to be destroyed. In 1990, copies of a normal ADA enzyme were inserted
into an inactive virus

a carrier; the carrier was then introduced to a young gir
l’s system
who was suffering from the "bubble boy" disease. The virus began to infect
the girl’s T
-
cells and the colony began to grow. She was then given several other
transfusions. In 1992 her treatment had proven successful and her immune syste
m had
grown very strong.





Although they might have a positive effect, new organisms created by genetic
engineering could present an ecological problem. The changes that a genetically
engineered species would make on the environment of a region are unpre
dictable. Just
like an exotic species, the release of a new genetically engineered species would also
have the possibility of causing an inbalance in the ecology of a region. An accident or an
unknown result could present several problems. An accident in e
ngineering the genetics
of a virus or bacteria could result in a stronger type, which, if released, could start a
serious epidemic. Even worse, accidents in human genetic engineering could cause
problems ranging from minor medical problems, to death. Genet
ic engineering could also
create unknown side effects or outcomes. Certain changes in a plant or animal could
cause unpredicted allergic reactions in some people which, in its original form, did not
occur. Other changes could make an organism toxic to huma
ns or other organisms.





Genetic engineering will ultimately arise many concerns. These concerns range
from ethical issues to a lack of knowledge on the effects genetic engineering may have.
One major concern is that once an altered gene is placed in an
organism, the process
cannot be reversed. Other concerns include: newly introduced genes may act differently
within a new host and the overall only term effect on an organism is unpredictable. There
are also certain ethical issues of major concern. "P
laying God" has become a
strong argument against genetic engineering. Despite all of these current concerns, the
potential for genetic engineering is tremendous. However, further testing and research
will be required to educate society on the positive
s and negatives to genetic engineering.
With the newfound breakthroughs in cloning, the capabilities of changing human
characteristics are unpredictable.





The most frightening scenario is the destructive use of genetic engineering.
Terrorist groups or a
rmies could develop more powerful biological weaponry. These
weapons could be resistant to medicines, or even targeted at people who carry certain
genes. Genetically engineered organisms used for biological weapons might also
reproduce faster, which would
create larger quantities in shorter periods of time,
increasing the level of devastation.





Like many other things, genetic engineering is a two
-
edged sword. Actually using
genetic engineering would eventually unleash all of its effects, both positive an
d
negative. After genetic engineering starts being used, our society will not simply be able
to "put it back", "turn it off", or otherwise remove it. Once it
becomes reality, it will always be with us. A study of all of the effects of g
enetic
engineering can lead to responsible use of the technology when it is fully developed.
Right now, however, there are no specific limits are on genetic engineering. We, as a
society, are technologically ready to carry out genetic engineering, but we m
ay not be
ready for the responsibility it brings.
