Introduction;
There has been much concern that organisms that have
been modified with powerful recombinant DNA techniques might sometimes be
dangerous. Could i
t be unsafe to eat a particular 'genetically engineered'
fruit or grain? Does
the genetic engineering limit children’s autonomy to shape their own destinies. This is the danger facing the world today. Human
beings have altered the genomes of species for thousands of years through
selective breeding, or artificial selection as contrasted with
natural selection, and more recently through mutagenesis. Genetic
engineering as the direct manipulation of DNA by humans outside breeding
and mutations has only existed since the 1970s. The term "genetic
engineering" was first coined by Jack Williamson in his science fiction
novel Dragon's Island, published in 1951, one year before DNA's role in
heredity was confirmed by Alfred Hershey and Martha Chase and two years before
James Watson and Francis Crick showed that the DNA molecule
has a double-helix structure. This process of “genetic engineering” refers to
the practice of adding new DNA to living things in order to create traits that
would have not naturally existed. This process can hinder the moral issues
particularly in religion. The question now is, can man possess the ability and
right to influence the course and law of nature? Looking at both sides, the genetic engineering argument
does raise questions that should be answered, not shouted down. Like all major
scientific advances, it probably has some negative effects, and steps must be
taken to improve these outcomes. There
has been more or less a consensus among some scientists who have published
analyses of ecological risks that most genetically engineered organisms (GEOs)
should be ecologically safe, though a minority could cause great problems. Yet
after years of analysis and discussion, the scientific community is still
divided over what this generality should suggest for regulatory oversight.
Genetic
engineering a serous treat to human society.
Sometimes, we do our best to satisfy our
immediate needs, as well as forgetting the future generations. Time shall come when those in the distant
future will look back on this period of history and they will likely see their
present era as when the natural environment was poor, because the
then present time will be full of artificial. Mark Zuckerberg made some mind-bending predictions
about the future at a Q&A he hosted on his Facebook page on 30th
June 2015, from the answers he gave, one can aver that the world is becoming
full of artificial. This power of allowing genetic engineers to build new
artificial genomes instead of having modified naturally existing genomes and it
applications, is unpredictable and dangerous, and broadening the application of
genetic engineering only furthers the risks because, most if not all engineered
organisms pose lethal and economic risks to human society. The most frightening scenario is the destructive use
of genetic engineering by the Terrorist groups or armies who 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. Likewise
the availability of genomic information and the genetic engineering technology
create a poisonous threat to humanity because; when the terrorists or armies
use both the information and technology to recreate deadly pathogens, such as
the poliovirus and the naturally occurring poliovirus which can kill and
paralyze millions of people in couple of years. Many chemical companies as well
want to use genetically engineered organisms to produce chemicals because it is
cheaper than normal manufacturing methods. If chemical companies begin to rely
on genetically engineered organisms to produce food and medical chemicals, the
public could be at risk for another dangerous outbreak of lethal chemicals
which will do more harm than good to the lives of the society.
Way out…
Like many other things, genetic engineering is a
two-edged sword, using genetic engineering would
eventually give a free rein to all of its effects, both positive and 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. It is true it has been
of assistance to man in many case like;
1.
With genetic engineering, most of the diseases and illnesses can easily be
prevented through isolating the exact gene that causes them.
2.
There are also infectious diseases that can be treated with the use of genetic
engineering. This is done by implanting the genes that are associated with
antigen and antiviral proteins.
3.
The most desirable traits of certain organisms can be pin pointed and
integrated into other organism’s DNA.
4.
Genetic engineering has the ability to increase the genetic diversity as well
as produce variant alleles that can be implanted to other species and other.
It is also possible to change the heredity of
the wheat plants and grow insulin. But a critical study of all of the effects
of genetic engineering can lead to responsible use of the technology when it is
fully developed. Right now, however, there are no specific limits that are on
genetic engineering. We, as a society, are technologically ready to carry out
genetic engineering, but we may not be ready for the responsibility it brings. Writer Dinesh D’Souza articulates
his position on this in a 2001 National Review Online article: “If parents are
able to remake a child’s genetic makeup, they are in a sense writing the
genetic instructions that shape his entire life. If my parents give me blue
eyes instead of brown eyes, if they make me tall instead of medium height, if
they choose a passive over an aggressive personality, their choices will have a
direct, lifelong effect on me.” In other words, genetic enhancement is immoral because it artificially molds people’s
lives, often pointing their destinies in directions that they themselves would
not freely choose. Therefore, it represents a fundamental violation of
their rights as human beings. The process of genetic engineering
is quite tricky and risky process and we need to gather a wide variety of
information before attempting to engage in the process of genetic engineering.
Keeping ourselves educated about all aspects of genetic engineering can help us
a lot because it will make us to understand that the genetic engineering
process involves gene and chromosome that has the ability to control the body
characteristics.
Conclusion.
Genetic engineering will ultimately arise many
concerns, and 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. God was not wrong when
he created us as we are, but we have insisted in changing the nature. Instead
of attempting to bury our heads in the sand, we should seek to harness genetic
engineering for its positive benefits, even as we take careful steps to
ameliorate its potential downsides. We should know that the world is made up of
warring opposite (cold verses heat, night verses day) as Anaximander stated. If
we should
consider the merit, let us as well consider the side effect and never transfer
artificiality to the next couple of generation to come. Considering what we are
witnessing now, time shall come when many natural things would have gone to
extinction. It was Albert Einstein who
said “Look deep into nature, and then you will
understand everything better”. I vehemently believe David Attenborough who said
that it seems to him that the natural world is the greatest source of
excitement; the greatest source of visual beauty; the greatest source of
intellectual interest. It is the greatest source of so much in life that makes
life worth living. Scientists tend to build a reputation on refuting the
theories of those who have gone before. Yet, whatever we hypothesize, observe,
measure or record about the natural world, it leaves more unanswered questions
(Robert Winston). Hence, let us
leave the world natural.
