The controversy surrounding genetically modified organisms (GMOs) has been raging since their introduction in the mids. The many scientists, organizations, governments and members of the public who are against GMOs have expressed concerns about the safety of the foods themselves, as well as the agricultural practices they are proliferating Dec 01, · Genetically modified (GM) foods contain at least one ingredient coming from a plant with an altered genetic composition. 16 Genetic modification, also known as genetic engineering, often introduces new, desirable characteristics to plants, such as greater resistance to pests. Many U.S. crops are grown using genetically engineered seeds, including a large share of the soybean, corn, cotton Sep 12, · Genetically modified (GM) crops are a controversial topic, which leads to intense public debate. This genetic engineering is supposed to make beneficial progress, whereas others believe it is prone to bring about hazards to either humans or the environment. This essay reveals valid arguments on
Why we write essays
The labeling requirement arose in response to public pressure and a confusing array of state rules. Farmers and agricultural scientists have been genetically engineering the foods we eat for centuries through breeding programs that result in large and largely uncontrolled exchanges of genetic material.
What many consumers may not realize: For many decades, in addition to traditional crossbreeding, agricultural scientists have used radiation and chemicals to induce gene mutations in edible crops in attempts to achieve desired characteristics. Modern genetic engineering differs in two ways: Only one or a few new genes with a known function are introduced into a crop, and genetically modified foods essays the new genes come from an unrelated species.
Thus, a gene meant to instill frost tolerance into, genetically modified foods essays, say, spinach, genetically modified foods essays, might come from a fish that lives in icy waters. In the decades since the first genetically modified foods reached the market, no adverse health effects among consumers have been found.
This is not to say there are none, but as hard as opponents of the technology have looked, none have yet been definitely identified. Although about 90 percent of scientists believe G. s are safe — a view endorsed by the American Medical Association, the National Academy of Sciences, the American Association for the Advancement of Science and the World Health Organization — only slightly more than a third of consumers share this belief. It is not possible to prove a food is safe, only to say that no hazard has been shown to exist.
The fears of G. s are still theoretical, like the possibility that insertion of one or a few genes could have a negative impact on other desirable genes naturally present in the crop. Among commonly expressed concerns — again, none of which have been clearly demonstrated — are unwanted changes in nutritional content, the creation of allergens and toxic effects on bodily organs, genetically modified foods essays. Establishing long-term safety would genetically modified foods essays prohibitively expensive decades of study of hundreds of thousands of G, genetically modified foods essays.
consumers and their non-G. Meanwhile, a number of impressive benefits have been well established. For example, an analysis of 76 studies published in February in Scientific Reports by researchers in Pisa, Italy, found that genetically engineered corn has a significantly higher yield than non-genetically modified varieties and contains lower amounts of toxins commonly produced by fungi.
Both effects most likely stem from the genetically engineered resistance to a major insect pest, genetically modified foods essays, the western corn rootworm, which damages ears of corn and allows fungi to flourish.
The researchers said that the change has had little or no effect on other insects. By engineering resistance to insect damage, farmers have been able to use fewer pesticides while increasing yields, which enhances safety for farmers and the environment while lowering the cost of food and increasing its availability. Yields of corn, cotton and soybeans are said to have risen by 20 percent to 30 percent through the use of genetic genetically modified foods essays. Billions of edible animals are raised in this country each year on feed containing G.
s, with no evidence of harm. In fact, animal health and growth efficiency actually improved on the genetically engineered feed, according to a review in the Journal of Animal Science.
Wider adoption of genetic engineering, especially in African and Asian countries that still spurn the technology, could greatly increase the food supply in areas where climate change will increasingly require that crops can grow in dry and salty soils and tolerate temperature extremes.
I continue to be distressed by the resistance to Golden Ricea crop genetically engineered to supply more vitamin A than spinach that could prevent irreversible blindness and more than a million deaths a year.
Nonetheless, gene modification scientists are focusing increasingly on building health benefits into widely used foods. In addition to pink pineapples containing the tomato-based antioxidant lycopene, tomatoes are being engineered to contain the antioxidant-rich purple pigment from blueberries. And people in developing countries faced with famine and malnutrition are likely to benefit from attempts to improve the protein content of food crops, as well as the amount of vitamins and minerals they provide.
This is not to say that everything done in the name of genetic engineering has a clean bill of health. Controversy abounds over the use of genetically modified seeds that produce crops like soy, corn, canola, genetically modified foods essays, alfalfa, cotton and sorghum that are resistant to a widely used herbicide, glyphosate, the health effects of which are still unclear.
In the latest development, resistance to a second weed killer2,4-D, has been combined with glyphosate resistance, genetically modified foods essays. The bottom line: Consumers concerned about the growing use of G, genetically modified foods essays. s in the foods they depend on might consider taking a more nuanced approach than blanket opposition. Rather than wholesale rejection, take some time to learn about how genetic engineering works and the benefits it can offer now and in the future as climate change takes an ever greater toll on food supplies.
Consider supporting efforts that result in safe products that represent improvements over the original and focusing opposition on those that are less desirable. Eat Are G. Foods Safe?
