To some people, genetic engineering is a hope of new beginnings, looking for such problems as the sh
ortage of organs, to which the perspective would be positive and mostly everyone would be looking fo
rward for the day that genetic engineering would save their love ones lives or their own. People see
what they want to see, and not even knowing the great risks that come with genetic engineering, to
such as the risk of health and other lives. The issue that is in everybody's mind is, should we use
genetic engineering? On my opinion we shouldn't, there is too much as we human beings have to loose,
our dignity as having full control of our self because as soon that society will start accepting ge
netic engineering, what would be next? Would we abuse the power that we have created by taking advan
tage of the technology? Would we use genetic engineering as a form of a weapon? There is a strong po
ssibility that we may proceed to that step, thus knowing our human nature, the abusing of power. Pla
nts are heavily depending on us, surviving thru the years by our technology, but soon that won't be
that essential since the genes of plants are being altered constantly. For example, tomatoes are se
nsitive to frost. This shortens their growing season. Fish, on the other hand, survive in very cold
water. Scientists identified a particular gene which enables a flounder to resist cold and used the
technology of genetic engineering to insert this "anti-freeze" gene into a tomato. This makes it pos
sible to extend the growing season of the tomato. Thus, increasing the possibilities of survival on
the tomato. People would think this is a good thing but there's always a downfall to good things for
example, Insects, birds, and wind can carry genetically altered seeds into neighboring fields and b
eyond. Pollen from transgenic plants can cross-pollinate with genetically natural crops and wild rel
atives. All crops, organic and non-organic, are vulnerable to contamination from a cross-pollination
. And this threatens our entire food supply. There is even more danger for example, Genetic enginee
rs use antibiotic-resistance genes to mark genetically engineered cells. This means that genetically
engineered crops contain genes which confer resistance to antibiotics. These genes may be picked up
by bacteria to which it may infect us. There is a lot to risk since scientist think only in increas
ing food growth they forget who is more important, the consumers. Animals have a similar situation
with plants since their genes are altered as well. Scientists have created a genetically engineered
variety of Atlantic salmon that grows to market weight in about 18 months, compared to the 24 to 30
months that it normally takes for a fish to reach that size. For fish farmers, raising these transge
nic fish could be faster and cheaper because it takes less feed and about half the time to produce a
crop they can send to market. This particularly problem is affective in conserving time and money b
ut this comes with a downfall. Since we don't know the effect of eating genetically engineered foods
and of course there is no recovery plan in case of disaster. In January 31, 2001. American scientis
ts created the world's first genetically engineered monkey. The scientists took a gene from a kind o
f jellyfish. They put it into a special virus that does not cause infection. Then they put the virus
into more than two-hundred eggs from rhesus monkeys. Only forty of the eggs were successfully ferti
lized and began to develop. The scientists placed the fertilized eggs into twenty female monkeys. Th
ree baby monkeys were born and survived. One monkey carried the jellyfish gene. Their goal was to cr
eate monkeys that have been genetically engineered to develop human diseases. Scientists could then
use the animals to study new treatments for humans with the disease. This is more of a bigger proble
m since now scientists have used endangered species such as the rhesus monkeys for their experiments
. The Scientists have moved up "the food chain" knowing who would be next for example, us and perhap
s their limit is their imagination. There was a time when 37 people died, 1500 were partially paraly
zed, and 5000 more were temporarily disabled by a syndrome that was finally linked to tryptophan mad
e by genetically-engineered bacteria. This shows how even genetic engineered disease and bacteria si
de effects can Kill. Instead of helping us its clearly killing us. The reason maybe that the techniq
ue for inserting a DNA fragment is sloppy, unpredictable and imprecise, the effect of the insertion
on the biochemistry of the host organism is unknown, and the effect of the genetically engineered or
ganism on the environment is unknown. Scientists knew these reasons before they started testing and
yet they risk the safety of human beings it shows how careless ones life can be for a careless exper
iment such as genetic engineering. "Genetic engineering bypasses conventional breeding by using arti
ficially constructed parasitic genetic elements, including viruses, as vectors to carry and smuggle
genes into cells. Once inside cells, these vectors slot themselves into the host genome. The inserti
on of foreign genes into the host genome has long been known to have many harmful and fatal effects
including cancer of the organism." Professor Mae Wan-Ho(Department of Biology) this professor knows
the consequences of genetic engineering and knows the great risk that one can take once again, human
life. Exotics are a danger matter to mess with since they are extinct. Last year a Japanese scienti
st cloned the first living mammoth by extracting the nucleus from the cell of a frozen mammoth, inje
cting it into an elephant's nucleated cell, and then implanting the viable embryo into an Asian elep
hant. Even though the baby mammoth only lived for a few days this represents a real step forward in
cloning dinosaurs. People wonder, how would it be like if dinosaurs would be brought back from extin
ction. Well that's easy it will be a dangerous matter to mess with since we have no long experience
in fact we have none, we may assume that we know how to handle it but of course things can go wrong.
Imagining exotics animals to be brought back, should stay as an imagination since there extinct for
a reason, and the reason for it is the strong survive I guess they where weak. Humans should not be
clone since the technique is extremely risky right now. Many attempts at animal cloning produced di
sfigured monsters with severe abnormalities. So that would mean creating cloned embryos, implanting
them and destroying those that look imperfect as they grow in the womb. However, some abnormalities
may not appear till after birth. There is another reason for humans not to be cloned since there are
powerful leaders in every generation who will seek to abuse this technology for their own purposes.
They may take advantage of this by possibly making a super army where the clones would be heavily a
dapted to any environment. And there will be no shortage of men. In any case there is a heavy chance
that if this proceeds any further there would be abusing of power. Yet, scientists do not understan
d living systems completely enough to perform DNA surgery without creating mutations which could be
harmful to the environment and our health. They are experimenting with very delicate, yet powerful f
orces of nature, without full knowledge of the repercussions. some people genetic engineering ho

would looking forward that genetic engineering would save their love ones lives their people what t
hey want even knowing great risks that come with genetic engineering such risk health other lives is
sue that everybody mind should opinion shouldn there much human beings have loose dignity having ful
