Should Genetic Engineering Be Legal?
The 70s in my opinion one of the most
important decade for
the evolution of knowledge about DNA and genetics. The
first discoveries were made by Gregor Mendel and his investigations on pea
hybridizations were published. Since then, there has been no going back,
scientists have been able to clone an entire DNA, to read people’s Genome and
transfer them from one cell to another.
I strongly believe, genetic engineering
has been one of the best discoveries scientists have made. With this we
welcomed the cure to millions of genetic illnesses that when mentioned before
scared and brought frustration to parents, making them think that it was their
fault and tearing families apart. Right now, genetic engineering is not only a
hope for each and every person who is diagnosed, but it’s also beneficial for all of us living in this
world, taking into account that it can be used in food production. This includes an increase in its yield, and as consequence, in its
production.
In addition to the mastering of this science, scientists have managed to improve the taste and nutritional value of food
products. And if that wasn’t enough, genetic manipulation reduces the losses
caused by various biotic and abiotic stresses, including fungal and bacterial
pathogens.
Another advantage this science offers to us, is the recombinant protein production, you obviously might be wondering what this means. In a very simple way, because of the recombinant DNA, we are
able to use bacteria to produce proteins for medical purposes. One of them, is
the genetically modified human insulin. This has solved the problem of pork
insulin intolerance, and has the additional advantage that its extraction is
less expensive. A final example is the growth hormone that may be useful in the
treatment of bone fractures, skin burns and ulcers bleeding from the digestive
tract.
But clearly in this life nothing can be
perfect, genetic engineering has more pros, but it isn’t excepted from the
cons. This is a radical technology considering that genes of unrelated
different species are combined and in consequence their genetic codes are
permanently altered.
These new organisms will pass their
genetic changes to their
off springs through inheritance. With this, human
beings are becoming the architects of life.
Thus, genetic engineering raises ethical
and social concerns. It also poses serious challenges for the environment,
human health, and animal welfare, among others.
Currently the biggest disadvantage in
genetic engineering is the use of this science to modify crops for the reason
that this could cause environmental problems. These could become invasive or
toxic for wildlife.
Until now, the most damaging impact of
genetic modification has been the phenomenon of resistance to pesticides.
Millions of acres of farmland have
become resistant to glyphosate herbicide. The excessive use of a trait designed
to tolerate the herbicide has promoted the accelerated development of
resistance in several weed species.
To conclude, Genetic Engineering
represents one of the most influencing advances and clearly one of the most
controverted ones. Since its results may alter for life humans and even their
living environment. In my honest opinion, this science is a great discovery for
the ratification of the existence of our future generations with the constant
need to cure diseases, but it’s really up to us to develop this science in a non-harming
way.
