In our contemporary society we are all more conscious of our decisions and the effects they have on not only our bodies but the effects on our environment as well. One of the things we as a society have started looking further into are the kind of foods we are buying, consuming, and growing, such as corn, tomatoes, soybeans among others. Many of these crops utilize genetic modification in order to meet the demand that the population requires to survive. According to the US Food and Drug Administration, 94% of soybeans planted were genetically modified, most corn in the United States is genetically modified and genetically modified canola accounted for 95% of canola planted. These genetically modified organisms, or for short they are commonly referred to as GMOs, are plants, animals, bacteria and other very small organisms that have had their DNA altered by scientists. At the end of the day we are responsible for what foods we consume and what the production of them does to our environment, so with this being said I disagree with the use of genetically modified organisms in our society because they have not been proven to be risk free and may become toxic and harmful for humans and the environment as well.
When people say that GMOs are virtually harmless to people, they are saying that without actually looking into the full scope of the claim itself. The truth is that genetically modified crops have not been proven to be completely risk free for human consumption. The FDA considers genetically modified crops substantially equivalent to that of non genetically modified crops therefore they do not require pre market approval in order to be distributed. The main issue with that is scientists do not know enough about the genetic and chemical make up of these genetically modified crops to ensure that the changes made on them are actually safe there have been FDA scientists that have consistently stated that “[t}here is a profound difference between the types of unexpected effects from traditional breeding and genetic engineering …This difference should be and is not addressed.” (Issues; G E Food) since altering the crops’ genetics could cause an increase in the level of toxins and could create entirely new undiscovered toxic reactions that could be very dangerous or fatal. The first test on a genetically modified crop was the callegene flavor savour tomato, these tests showed that the consumption of this crop caused rats to have stomach lesions and knowing this, according to Issues: | Food Safety, FDA Officials decided to ignore the scientific evidence and deem genetically modified crops safe, and didn’t need premarket approval without notifying the public. This is significant because citizens who are consuming these foods cannot look further into the foods they are eating and therefore are robbed of knowing the effects of the food they are consuming. This resulted in a lawsuit against the FDA where they admitted that they had made no conclusive findings about the safety of genetically modified foods. This shows that we are not able to prove without a doubt that GMOs are safe to consume.
One may ask how difficult it may be to pinpoint what foods are safe to consume and which are not. In one study done on the negative effects of bt corn on non target species researchers found that certain effects may be subtle and complex. Which in turn, makes it easy to overlook them when doing a risk assessment during the registration process to gain approval for production from the government. A combination of genes are used from organisms such as plants, animals, and bacteria in order to genetically modify something. The then created GMO does not occur through the traditional crossbreeding methods thus it is called a transgenic crop. Doing this kind of genetic engineering eliminates most of the chance of these transgenic crops of having any undesirable traits but doesn’t mean they can’t mutate or develop new traits later down the line. Smaller or less complex organisms like plants and bugs have a quicker rate of growth compared to other organisms like humans. Researchers have noted that “A recent study has shown that monarch larvae reared for 96 hours in the laboratory on milkweed leaves dusted with pollen from Bt corn suffered significantly higher mortality (44%) within 96 hours than did larvae reared on leaves dusted with untransformed corn pollen or leaves without pollen.(Losey et al. 1999).” Transgenic Insecticidal Corn: Beyond Insecticidal Toxicity to Ecological Complexity. With this it is easy to determine that genetically altered crops could have an effect on people in the long run. With this being said it is shown that we are unable to actually determine if these GMOs are safe for use long term.
These genetically modified crops have the ability to damage the environment. It’s been scientifically proven that most of the crops that are genetically modified are a kind of invasive species (Mitchel et al. 2019) “Regulation of GM Organisms for Invasive Species Control.” This can cause a catastrophic effect on the biodiversity of the area where these crops are planted. One major focus of concern is that genetically modified crops will crossbreed with each other and this can cause this new trait to spread and affect other invasive species. “The issues of risk of GM crops deal with the ecology and toxicology of GM crops upon release and use. There is a continued discussion whether more broad ’risks‘ should be part of the basic biosafety assessment” (Commandeur et al., 1996; Sagar et al., 2000) “The release of genetically modified crops into the environment”. This can cause these other species to have the same survivability as the GMO and can make it extremely hard to dispose of them. This could result in an environmental disaster affecting the food chains of every biome and potentially advance the development of the extinction process. Furthermore, the use of GMOs in the environment can lead to the development of super diseases and/or pests that would have complete immunity against traditional control methods. This can completely devastate natural organisms and genetically altered ones as well since these new pests/diseases could have the same or even advanced traits due to crossbreeding or mutations.
Even though all of these problems have been unfounded none of them are going to be instant changes. Which proves nothing other than what the possibilities could be. We can’t really know as of now if GMOs are entirely safe, just because it is unfounded now doesn’t mean it can’t develop in the future. This evidence is leading us to believe that we should be wary when deciding whether or not genetically modified foods are really safe or if it is worth the risks.
Ultimately, we do not know the possibilities of what can happen or be done by scientists in the process of modifying our crops genetically. This is why we should be against the use of these methods when cultivating our food, caring for our environment, and creating GMOs.
