Advantages and disadvantages of g.m.o

Surely you have heard the term “genetically modified organism” (GMO) everywhere, from high-ranking government authorities to consumers in the aisles of the supermarket, but always accompanied by controversy.

Opinions on GMOs are often extreme and confronting, and it is common to find advocates and detractors agree that these products are going to save the world, or on the contrary, should be removed from our plates. Like everything else in life, the truth is probably located, not necessarily in one of these extremes, but somewhere in the middle.

Both sides of the story
Why so much gibberish ? First, let’s look at an exact definition to put the term GMO in context. Genetically modified organisms are defined   as ” living organisms whose characteristics have been changed, using modern techniques in specialized laboratories, to introduce genes that come from other species. These techniques allow separating, modifying and transferring parts of the DNA of a living being (bacteria, virus, plant, animal or human) to introduce it in another. “

Advantages of g.m.o

Genetically modified organisms can exist in the form of plants, animals and microorganisms. In the case of plants, they are known to offer a wide range of benefits to the producer, such as resistance to pests and diseases, tolerance to herbicides, ability to adapt to extreme environmental circumstances, and in some cases, superior nutritional value.

Another important element of contention, postulated by some pro-GMO enthusiasts, is that due to the implicit tolerance and resistance to plagues and diseases that these crops present, yields will increase naturally, which is why some believe that their existence throughout of time will alleviate stresses associated with the supply of food to a growing global population.



Disdvantages of g.m.o

Despite the advantages, the coin has another face, as expected. Several potential risks associated with GMOs have surfaced in recent years, causing alarm among certain sectors of the population. Questions about how GMOs affect the environment and human health are fundamental concerns for producers, consumers and other members of the industry, and in some cases the public has pushed for laws that require companies to label products that contain GMO .

  1. Transfer of allergens from one organism to another
  2. Transfer of antibiotic resistance markers
  3. Violation of the intrinsic value of natural organisms
  4. Loss of biodiversity in flora and fauna
  5. Biopiracy or foreign exploitation of natural resources
  6. Interference with Nature by mixing genes between species
  7. GM foods can present significant allergy risks for people, according to Brown University. The genetic modification often mixes or adds non-original proteins to the plant or animal, causing new allergic reactions in the human body.


However, the state of California in the United States recently rejected a proposed law to label foods containing GMOs (51.5% of votes), but the emotions on the matter are still on the surface. Proponents of the proposal continue to promote it and insist they are prepared to “intensify the energy of their struggle for Prop 37 (Mandatory Labeling of Genetically Engineered Food),” according to a press release from a pro-GMO coalition.

It should be noted that no report has been published indicating that, in effect, GMOs cause adverse effects on human health and several academies and recognized international associations have reported that GMOs do not present in themselves greater risks than plants obtained by technology. conventional genetic improvement. It is safe to say that most of the points of concern alleged are rather a reaction to the potential and uninvestigated effects of GMOs, and the possible harm that these organisms could cause in humans, than actual damage that has actually been documented.

Despite these reports, many supporters of the anti-GMO side of the debate believe that it is necessary to continue investigating the production of GMOs because they believe that many investigations conducted previously were not exhaustive enough, or could have been influenced by the interests corporations that promote the use of these organisms, and in general, that the production of GMO is in continuous evolution and consequently requires continuous research and critical evaluation.
