Food insecurity: Prevalence, causes, and the potential of transgenic `Golden Rice'
Decrease in Global Warming As more plants and crops can be grown and at more areas, including those that were previously unsuitable for farming, oxygen in the environment is increased, decreasing the proportion of carbon dioxide and, in turn, reducing global warming. Stronger Crops Another benefit that GM technology is believed to bring about is that crops can be engineered to withstand weather extremes and fluctuations, which means that there will be good quality and sufficient yields even under a poor or severe weather condition.
Allergic Reactions According to research by the Brown University, resent genetically modified foods can pose significant allergy risks to people. Download: Advantages and disadvantages of genetically modified foods pdf disadvantages essay pros and cons of Geneticaly Modified Crops.
These advantages and disadvantages of genetically modified foods show us that it offers a window to greater food production for a changing world. The climate has been growing warmer. Advantages and. New Products New kinds of crops are being developed to be grown at extreme climates, such as those present in dry or freezing environments. Food Supply at Risk GMO seeds are patented products and, in order to purchase them, customers have to sign certain agreements for use with the supplier or creator.
This means your range of food choices will be lessened. Considering that they are modified using viruses and bacteria, there is a fear that this will certainly happen. It states that genetic modification often adds or mixes proteins that were not indigenous to the original animal or plant, which might cause new allergic reactions in our body. These products might encourage authorities to implement higher tariffs to merchants, who would be selling them. And when we eat them, these antibiotic markers will persist in our body and will render actual antibiotic medications less effective.
More Income With genetic engineering, farmers will have more income, which they could spend on important things, such as the education of their children for example.
Extensive Protection for Crops GM foods were created with the use of genetic engineering—a technology that was designed to make sure crops will never be damaged in a fast rate. This threat to human health is a worrisome aspect that has received a great deal of debate.
The technique used in this type of crop management has been introduced to ensure farmers and merchants are able to improve crop or food quality in a more efficient way. The primary advantage of genetically modified foods is that crop yields become more consistent and productive, allowing more people to be fed. In some cases, proteins from organisms that you are allergic to might be added to organisms that you were not originally allergic to. Here are their advantages and disadvantages: 1.
As an example, scientists have developed a new type of tomato that grows in salty soil. Moreover, larger companies might have more political power and might be able to influence safety and health standards. You can also read a brief fact sheet to familiarize yourself more with their purported benefits and problems. Economic Concerns Bringing a genetically modified food to market can be a costly and lengthy process, and of course, agricultural bio-technology companies want to ensure a profitable ROI.
Lower Level of Biodiversity One big potential drawback of this technology is that some organisms in the ecosystem could be harmed, which in turn could lead to a lower level of biodiversity. Gene Spilling It is unclear what effects, if there are any, the genetic pollution resulting from inadequate sequestering of genetically modified crop populations would have on the wild varieties surrounding them.
Not Totally Safe to Eat It is proven by scientific studies that GMO foods contain substances that may cause diseases and even death to several kinds of species in this world, including us humans. The oceans have been slowly acidifying.
Being around since , they are produced in a way that is very similar to genetic engineering. In addition, genetically modified crops could prove toxic to some organisms, which can lead to their reduced numbers or even extinction. As people in poorer countries spend over half of their income on food alone, this means automatic reduction of poverty. Decreased Antibiotic Efficacy According to the Iowa State University, some genetically modified foods have antibiotic features that are built into them, making them resistant or immune to viruses or diseases or viruses.
Furthermore, these seeds structurally identical, and if a problem affects one of them, a major crop failure can occur. A literature review on the safety assessment of genetically modified plants.
Larger Production It has been easier to raise crops that are classified as genetically modified because all of their examples have the stronger ability to resist pests. There would be fewer competitors, which could increase the risk of oligopolies and food price increases. Unusual Taste Genetically modified foods are observed to have unnatural tastes compared with the ordinary foods that are sold on the market. Exploitations Some countries may use genetic engineering of foods as a very powerful weapon against their enemies.
Environmental Protection According to an Oklahoma State University report, the increase of GM animals and crops often requires less time, tools and chemicals, and may help with reducing greenhouse gas emissions, soil erosion and environmental pollution. This means the amount of pesticide chemicals used on the plants are reduced, so their exposure to dangerous pesticides are also reduced. The university also warns that ingestion of these foods and regular exposure to antibiotics may contribute to the reduced effectiveness of antibiotic drugs, as noticed in hospitals across the planet.
Another good discovery in genetic engineering of plants is the exclusion of the gene responsible for caffeine in coffee beans, creating decaffeinated coffee beans, which can then be grown naturally. So, many new plant genetic engineering technologies and products have been patented, and patent infringement is a big concern within the agribusiness.
Insect Resistance Some GMO foods have been modified to make them more resistant to insects and other pests. We can just think of the technology as a vaccine for the species, except that it is encoded into their genes, rather than being shot into their immune system.
Decrease in Food Prices Due to higher yield and lower costs, food prices would go down. However, it is stressed that releasing pollen from genetically altered plants into the wild through the insects and the wind could have dramatic effects on the ecosystem, though there is yet long-term research to be done to gauge such impact.
This not only helps people get the nutrients they need, but also plays a significant role in fighting against malnutrition in third-world countries. This could be the result of the substances that were added to their composition.

This paper reviews a number of recent social science publications on the nature and causes of food insecurity in low and middle-income countries. The focus is on one specific element of food insecurity, vitamin A deficiency, which is widespread in developing countries and causes blindness and early death among millions of children. The paper explores the pros and cons of this recently developed transgenic rice variety, and tries to answer the question whether in this particular case, genetic modification technology provides a solution to food insecurity. It is concluded that Golden Rice is one of the options available, but not necessarily the most effective one. This is a preview of subscription content, access via your institution.

genetically modified food advantages and disadvantages pdf
The global area sown to genetically modified GM varieties of leading commercial crops soybean, maize, canola, and cotton has expanded over fold over two decades. Crop production and productivity increased significantly during the era of the adoption of GM crops; some of this increase can be attributed to GM technology and the yield protection traits that it has made possible even if the GM traits implemented to-date are not yield traits per se. GM crops have also been credited with helping to improve farm incomes and reduce pesticide use. Practical concerns around GM crops include the rise of insect pests and weeds that are resistant to pesticides. Other concerns around GM crops include broad seed variety access for farmers and rising seed costs as well as increased dependency on multinational seed companies.

The previous chapter discussed the difficulty of attributing changes in health outcomes directly to foods from new crop varieties, whether genetically engineered or conventionally bred. Assessing social and economic effects 1 of genetically engineered GE crops is similarly challenging. GE crops were introduced to farmers in rural communities with varying social structures and heterogeneous, and often complex, farming systems. Those systems vary in numerous ways, including type of crop or crops grown, production location, farm size, farmer education, level of government policy support to farms including incentive systems for particular crops or farming practices , and availability of credit to farmers.
Engineers design plants using genetically modified organisms, or GMOs, to be tougher, more nutritious, or taste better. However, people have concerns over their safety, and there is much debate about the pros and cons of using GMOs. A manufacturer creates GMOs by introducing genetic material, or DNA, from a different organism through a process called genetic engineering. They must meet the same safety requirements as traditional foods. There is some controversy over the benefits and risks of GMO foods. In this article, we discuss the pros and cons of GMO crops, taking into account their potential effects on human health and the environment.
Many consumers in the European Union, regardless of their level of education or nationality, take a critical distance from genetic engineering in food production. Several surveys have repeatedly shown that their vast majority do not want GM foods. GMOs create a path that leads to advantages and benefits, but also raises extremely important questions. Even over 20 years after the introduction of gene plants, we still lack on an extensive study on effects of genetically modified plants on humans. Genetic engineering is a tricky issue and not everyone has specialized knowledge. It is therefore particularly easy to influence consumer opinions with little effort.
This is the question in the ongoing debate of pros and cons of GM food. Food is an emotional topic. It matters a great deal to all of us. We are what.
