This paper argues that genetically modified foods pose significant risks to human health and the environment that outweigh their benefits. It examines three primary concerns: environmental contamination from transgenic crops, documented health hazards including stunted growth and immune dysfunction, and allergic reactions from novel proteins created through gene splicing. The paper also traces the commercial history of GMOs beginning with the FDA-approved Flavr Savr tomato in 1994, and analyzes the economic pressures farmers face as large biotech companies like Monsanto dominate the market. The author concludes that while GMOs may offer increased nutrition, insufficient testing and unknown long-term effects make them unsafe for regular human consumption.
Genetically modified foods have become increasingly prominent in society and in the minds of families considering what to eat. While GM foods are designed to offer greater resistance to viruses and higher nutritional value, they present serious potential risks and ethical concerns. Genetic engineering is morally problematic and carries many potential risks that outweigh its benefits, including documented health hazards and violations of the natural order of the world. GMOs are unsafe to human wellbeing, and transgenic harvests can lead to destruction of the environment and contamination of food crops.
Transgenic harvests have damaged the environment and contaminated organic food crops. Although transgenic crops were designed with insect resistance and herbicide resistance to reduce environmental contamination, these traits can easily spread to natural ecosystems. This dispersal can lead to genetic mutation in insects and other organisms within the environment. The consequences could be devastating, as natural ecological restoration may be jeopardized by mutations caused by biotechnology in these crops. The U.S. Environmental Protection Agency (EPA) is responsible for regulating pesticides, and it has confirmed that GMO crops pose serious ecological risks because of the toxins used to kill insects.
One major risk of genetically modified foods is the unknown effect of long-term human consumption. Research suggests that "consumption of these genetically engineered foods can cause the development of diseases which are immune to antibiotics. Moreover, according to some experts, people who consume such foods have high chances of developing cancer" (Kartha). GM foods have not been adequately tested for human consumption, and significant evidence points to probable harm to health.
A landmark study conducted by Arpad Pusztai at Rowett Research Institute in 1998 demonstrated these dangers. Scientists fed rats a diet of GM potatoes, and the results were striking: rats expressing a gene coding for a snowdrop sugar-binding protein showed stunted growth and reduced immune function (Arpad, 1998). This evidence demonstrates that GM foods can be very harmful to human health.
One of the most commonly perceived risks of GM foods is an increase in allergies across large populations. Many experts worry that if protein genes are being spliced and rearranged, it becomes difficult to determine whether foods contain unknown proteins from other organisms that could trigger allergic reactions. The process of splicing proteins into genetically modified foods potentially creates new allergens.
Gene splicing introduces a new gene into an organism, which in turn creates a new protein. These novel proteins can be consumed by organisms and produce unknown allergic effects. Scientists cannot predict these allergies in advance because they are difficult to forecast (Lilliston & Cummins). Proteins are the leading cause of allergic reactions in common foods such as milk, eggs, nuts, wheat, fish, peanuts, and soybeans. Critics of genetically engineered food argue that these proteins or other novel allergens could enter other foods, exposing highly allergic individuals to unknown substances without their awareness. The FDA argues that new genetic techniques use better methods than traditional breeding, allowing greater predictability and accuracy when exchanging genes. However, the mechanism of gene splicing—introducing new genes that create new proteins repeated throughout an organism—remains a genuine source of allergic risk.
The introduction of GMO foods began in 1994 when the Food and Drug Administration approved the first genetically modified food for sale on grocery shelves: the Flavr Savr tomato (GMOinside). This sparked societal interest in a significant departure from the traditional expectation of natural produce. However, this shift is not entirely surprising given how history repeatedly changes through departures from traditional methods. Like all evolutionary developments, food production has also evolved. Current research and industry leaders claim that genetically modified crops can grow faster and at lower cost. From these claims, it can be assumed that today's farmers will adopt these new procedures to increase profitability. From this point forward, the competitive agricultural market shifted focus from quality to quantity.
Consumer expectations, however, work against widespread GMO adoption. Consumers generally expect produce to be natural and are more likely to reject foods associated with GMOs, potentially decreasing demand. The major problem with this outcome is that farmers who have already invested money and signed contracts with large companies such as Monsanto—a company that produces herbicides along with GMO seeds—may be forced out of business. Furthermore, major corporations such as Monsanto often pressure farmers to buy their products by pricing them lower than competitors. In these situations, farmers must either conform to growing GMO products like Roundup Ready crops or abandon farming altogether. In both scenarios, GMO products continue entering the market and becoming part of consumers' diets. The critical issue is how traditional farmers, once stable and competitive, now struggle to adapt to constantly growing demand while pressured by large biotech corporations.
In conclusion, the world is unsure of the effects of foods created by extracting DNA from an adult organism and forcing it into the beginning cell of another organism, thereby manipulating its natural course and creating genetically modified food. As one researcher notes, "Selective breeding over time created these wide variations, but the process depended on nature to produce the desired gene" (Harvie). With this in mind, it is in the best interest of people and their health to exercise caution before regularly consuming genetically modified food products. While increased nutrition may benefit the body, the potential harm should not be overlooked. Although GMOs may offer greater nutritional value, society may not yet be ready to embrace scientific food products whose long-term effects remain unknown and whose risks remain inadequately tested.
