Advantages And Disadvantages Of Genetically Modified Foods

Some advantages of genetically modified foods include: a higher yield of crops per hectare, this means that we put a lesser strain on the environment in order to meet our agricultural needs. The GM foods also has more nutritional value which aids in combatting malnutrition in less developed countries. Insect/pest resistance also increases drastically, according to the Nuffield Council on Bioethics. Disease resistance also increases, an example would be the bananas newfound resistance to the Black Sigatoka fungus which can reduce the yield of bananas by up to 70%. GM foods are also able to tolerate herbicides, an example of this would be Argentina in 2002 where 90% of the soybeans grown were genetically modified to tolerate herbicides. GM crops are now also able to resist environmental stress (such as drought, heat, frost, etc.) Recently a gene which allows rice to produce a sugar that protects it during periods of dehydration has been introduced to allow it to withstand drought. However, there are some disadvantages about GM food. After a study done by Gilles-Eric Seralini in 2012 many claim that there is a link between GM foods and cancer. The study showed them feeding rats a diet of GM corn that is resistant to the herbicide ‘Roundup’. It was then shown that these rats had a higher chance of getting tumours. However many argue against this claim as there were too few rats in the control group to make a valid comparison. Many also believe that with GM foods resistant to
