The Effects of Genetic Engineering Some scientists involved in the field of genetic research h
ave 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 people 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 live
s. 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 ge
nerations. It could also allow people with family histories of diseases, such as cancer, to "fi
x" their genetic predisposition to the disease. Another way that genetic engineering coul
d affect our lives is its application to plants and animals used for food. If farmers breed plants a
nd animals specifically engineered to produce more meat or fruit, faster and easier than normal, the
n food would become cheaper and more plentiful. In addition, genetic engineering might allow the cre
ation of better tasting, or more nutritious foods. Genetic engineering can also be applied in
the fight against diseases. Through genetic engineering, people could maintain their lifestyles with
out the threat of AIDS or cancer. People of the world would not have to live in fear of contractin
g a deadly virus or hereditary disease. In theory, genetic engineering can accomplish this. Genetic
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&quot
; disease, diabetes, and several more. Cystic fibrosis is the leading hereditary cause of death amon
g 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 diseas
e is characterized 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 inactiv
e virus—a carrier; the carrier was then introduced to a young girl’s system who was suffering from t
he "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 system 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 gen
etically engineered species would make on the environment of a region are unpredictable. Just like a
n exotic species, the release of a new genetically engineered species would also have the possibilit
y of causing an inbalance in the ecology of a region. An accident or an unknown result could present
several problems. An accident in engineering 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 ge
netic engineering could cause problems ranging from minor medical problems, to death. Genetic engine
ering 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. Oth
er changes could make an organism toxic to humans 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 i
n an organism, the process cannot be reversed. Other concerns include: newly introduced genes may ac
t differently within a new host and the overall only term effect on an organism is unpredictable. Th
ere are also certain ethical issues of major concern. "Playing God" has become a strong ar
gument 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 societ
y on the positives and negatives to genetic engineering. With the newfound breakthroughs in cloning,
the capabilities of changing human characteristics are unpredictable. The most frightening sc
enario is the destructive use of genetic engineering. Terrorist groups or armies could develop more
powerful biological weaponry. These weapons could be resistant to medicines, or even targeted at peo
ple 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 l
evel of devastation. Like many other things, genetic engineering is a two-edged sword. Actuall
y using genetic engineering would eventually unleash all of its effects, both positive and negative.
After genetic engineering starts being used, our society will not simply be able to "put it ba
ck", "turn it off", or otherwise remove it. Once it becomes reality, it will always b
e with us. A study of all of the effects of genetic engineering can lead to responsible use of the t
echnology when it is fully developed. Right now, however, there are no specific limits are on geneti
c engineering. We, as a society, are technologically ready to carry out genetic engineering, but we
may not be ready for the responsibility it brings.effects genetic engineering some scientists involv
