GENETICALLY MODIFIED CROPS
Genetic engineering is the modification of an organism's genome using
biotechnology. Modification includes transfer of genes within or across species as well as
through molecular cloning. Various methods are used to manipulate the genomes. Crops
whose genes have been altered are referred to as genetically modified crops.
One method involves isolating and thereafter replicating the DNA material to produce
identical copies. The DNA material is then inserted into the organism in this case crops.
Removing genes can be done using nuclease. Genetic targeting is a method used to add,
remove or to mutations. These techniques are referred to as recombinant DNA technology
(Halford, 2003). The most common method involves shooting radiation onto the target genes
using a gene gun and has proven most successful in monocotyledons (Liang & Skinner,
Genetic engineering is performed in order to introduce traits which do not occur
naturally but are highly regarded as crucial. Such traits include; longer shelf life, resistance
to disease, adaptation to certain climate, herbicide tolerance and increased yield (Atherton,
2002). A crop could be high yielding, mature faster but be highly susceptible to disease.
Another variety of the same crop could take longer to mature while be highly resistant to
disease. The disease resistance trait is introduced to the high yielding variety thereby altering
the original structure of the crop.
There have been several concerns over genetically modified crops as is with any new
technology. Following the myths surrounding them, some countries have banned the use of
the crops with some partially accepting them while keeping their use in close observation
(Bodiguel & Cardwell, 2010). This is despite the fact that the technology has been
scientifically proven to be safe with them being equally comparable to unaltered food crops.
It is also important to note that mutation naturally occurs. The technology has been around
since the late 80s with the first commercial sale being in 1994 involving altered tomatoes to
increase shelf life.
The public seems to believe that the crops pose a health risk with some even going as far as proclaiming they cause cancer, which is completely unfounded. Several
organisations have pushed for the removal of the crops from the market to allow for further
studies. They claim that there could be long could be long term health risks which are yet to
be observed. An example is the rise of allergies in children which requires further research.
There are concerns that the altered crops will become resistant to conventional
herbicides and as a result becomes invasive (Ferry & Gatehouse, 2009). This means that these
crops could end up growing in unwanted places hence being termed as weeds. Modified
crops that are used to produce pesticides produce highly toxic pesticides and pose a risk even
before they are manufactured. Bees and butterflies may also be affected largely due to new
agricultural practises which do not require them to aid in pollination (Andow, Hilbeck, &
Tuất, 2008). The pesticides used against the GMOs also pose a risk on birds.
Cross pollination is bound to happen with conventional crop
