Vitamin A deficiency is the leading cause of preventable childhood blindness, identifying that this problem affects over 250 million children worldwide, mostly in South Asia and Africa (UNICEF data from The World Health Organization, 2014). Associated childhood deaths arise usually as a complication from a weakened immune system, such as infection or diarrhoea. The introduction of Genetically Modified foods containing beta-carotene could assist to prevent this blindness and related deaths. It is because of this that this report will support the use of genetically modified foods.
Genetic Modification and Gene Splicing
Genetic Modification (GM) refers to the use of modern biotechnology techniques such as Gene Splicing to change the genes of an organism, such as a plant or animal. GM is of benefit as it alters an organism’s genes to provide improvement and development of the species by using desirable characteristics in the process of Gene Splicing.
In Gene Splicing, fragments of DNA from one or more different organisms are inserted into plant genomes and combined to form recombinant DNA. The organisms will now express the desired traits and are made to “function within the cells of a host organism” (Houghton Mifflin, 2002) (Mission 2014: Feeding the world). Several crops, including cotton, maize and soybean have gone through this process and are now Genetically Modified to be resistant to non-selective herbicides. They are now “enabled to degrade the active ingredient in…
