With widespread introduction of GMOs in recent decades, especially in commercial food, some consumer advocates have mobilized to question the potential health and environmental risks associated with GMOs.

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.

Advantages and Disadvantages of Genetically Modified Foods Advantages of Genetically Modified Foods

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. Proponents predict that genetic engineering would increase yields in the fields due to the characteristics above, although this would not reach the desired level of food security.

Hunger and malnutrition are issues that often require additional social and political strategies. Efforts are needed to maintain and develop varieties and cultivation methods should be adapted to the local needs together with the local population.

The only efficient way to reduce the proportion of undernourished locally is by using conventional means — for example by cultivating traditional food plants such as cassava root, but also through targeted support projects, educational programs, nutritional advice and political activities. A multi-dimensional strategy is necessary that creates suitable, specific activities for each situation.

In addition, once genetically modified plants have been introduced into the world, they often can no longer be retrieved: they can actively spread, multiplied, passing on their genetically modified properties to other organisms and influence each other, with all, largely unexplored consequences for the environment, animals and people. All new genetically modified crops have to be checked for harmlessness to humans, animals and the environment before they are approved, but many scientists describe the current regulations for risk assessment as insufficient.

Farmers are already using the variety of conventional plants that are adapted to their respective environmental conditions such as drought, flooding or high salinity in the soil. Drought-tolerant crops grown conventionally already exist. The genetic engineering industry has promised a lot, but so far has not yet presented a solution for a secure return on climate change.

New genetic engineering methods , so-called genome editing, are to lead more quickly to plants that can withstand abiotic stress such as drought and high salinity.

They are placed in the foreground as the solution to the problem of climate change. In practice, companies continue to focus on commercial applications such as herbicide tolerance or feed quality. The promotion of alternative research in the sense of sustainable agriculture with more comprehensive, multi-dimensional approaches seems more effective here.

Regarding food quality , what we can say is that genetic engineering is not necessary for a healthy diet. In our industrialized nations, the variety and range of good quality food have never been as large and available all year round as it is today. Thanks to improved food hygiene, quality assurance systems and optimized detection methods, our food had reached a high safety standard even before the introduction of genetic engineering.

The savings in weed killers herbicides in the cultivation of herbicide-resistant crops HR crops highlighted by seed companies is controversial. Various studies show that the results are dependent on various factors, such as the growing conditions and climatic conditions at the location.

Figures show a significant increase in spray consumption since the introduction of genetic engineering in the field.

Due to the increasing development of resistance in weeds to the herbicides used, farmers not only have to increase the dose, but they also have to use additional active ingredients. Another consequence is that the genetic engineering industry is developing crops that can withstand higher doses of herbicides or are multi-resistant to various herbicides.

Furthermore, the constant confrontation of the insects with the Bt poison certain GM crops produce toxins that are lethal to insects has already led to the emergence of resistant pests.

Instead of using fewer sprays, these pests need to be combated with other or additional pesticides. Created in , the ProTerra Standard has a long-standing history and experience in promoting sustainability in the food and feed supply chain and segregated non-GMO materials. Among others, one of its aims is to secure the supply of sustainably produced, fully traceable, non-GMO ingredients for feed and food. Besides, our packaging label is a mean by which brands can communicate the non-GMO and sustainability commitment directly to consumers and stakeholders.

January 28, am. PROS Most of the genetically modified plants present the following benefits: Tolerance to atmospheric stress, such as extreme temperatures, salinity, drought and floods; Resistance to viruses, fungi and bacteria; Herbicide tolerance; Insect resistance.

CONS On the other hand, the use of GMOs brings risks, such as: Changes in the interaction between plant and biotic environment: Persistence and invasiveness; Selective advantages or disadvantages; Transfer of genes; Interactions with target organisms e.

Changes in the interaction between plant and abiotic environment: Alterations in Greenhouse Gas Emissions; Variations in sensitivity to climatic effects; Modifications in sensitivity to soil abiotic factors salinity, minerals …. Harm to human or animal health: Toxicological effects; Allergenicity; Changes in nutritional value; Transfer of antibiotic resistance. The Counterpoint: Climate Change Farmers are already using the variety of conventional plants that are adapted to their respective environmental conditions such as drought, flooding or high salinity in the soil.

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. Citizens in many countries and especially in European countries are opposed to GM crops and have voiced concerns about possible impacts on human and environmental health. Nonetheless, proponents of GM crops argue that they are needed to enhance worldwide food production.

Food insecurity: Prevalence, causes, and the potential of transgenic `Golden Rice'

Genetically modified organisms or GMOs are a product of a form of scientific farming, where crops are administered with chemicals to increase their sizes and yields. It is becoming more and more common in many types of food we see every day. But due to its concept, it has been a topic in heated debates around the world, with proponents and opponents pushing their arguments. Here are the critical GMOs advantages and disadvantages:.

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.

Email: jennifer. The year marked the 20th year of the commercialisation of genetically modified GM crops. During the period from to , the global hectarage of these crops increased fold, making it the fastest adopted crop technology in recent times. The overall economic gains from these crops have been estimated to be USD The environmental benefits include contributing to the practice of minimal till agriculture and a decrease in the use of pesticides.


Genetically modified foods are made by inserting genes of other species into their DNA. Though this kind of genetic modification is used both in plants and animals.

Genetic modification is a special set of gene technology that alters the genetic machinery of such living organisms as animals, plants or microorganisms. The principal transgenic crops grown commercially in field are herbicide and insecticide resistant soybeans, corn, cotton and canola. There are bananas that produce human vaccines against infectious diseases such as hepatitis B, fish that mature more quickly, fruit and nut trees that yield years earlier and plants that produce new plastics with unique properties. Technologies for genetically modifying foods offer dramatic promise for meeting some areas of greatest challenge for the 21st century. Like all new technologies, they also pose some risks, both known and unknown. Controversies and public concern surrounding GM foods and crops commonly focus on human and environmental safety, labelling and consumer choice, intellectual property rights, ethics, food security, poverty reduction and environmental conservation.

The pros and cons of GM crops

 Какого черта, - промычал он себе под нос. Под его ногами была потайная дверь, почти неразличимая на полу.

На рубашке расплывалось красное пятно, хотя кровотечение вроде бы прекратилось. Рана была небольшой, скорее похожей на глубокую царапину. Он заправил рубашку в брюки и оглянулся. Позади уже закрывались двери.

Она ударила его подушкой. - Рассказывай. Немедленно. Но Дэвид знал, что никогда ей этого не откроет.

Срочно. Она попыталась собраться с мыслями. - Сегодня суббота, сэр.
