Engineers design plants using genetically modified organisms, or GMOs, to be tougher, more nutritious, or taste better.

The genetic engineering is one of the great marvels of 21st century human. It allowed for precise control over the genetic changes introduced into an organism.

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.

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.

What are the advantages and disadvantages of Genetically Modified or GM Crops?

Subscriber Account active since. Genetically modified organisms GMOs are living organisms that have had their genes altered in some way. GMOs can be animals or bacteria, but most often they are crops like corn or potatoes that have been tweaked in a lab to increase the amount or quality of food they produce. There are many advantages of GMO crops, but some groups have raised concerns that GMOs may have negative health effects. Here's what you need to know about the pros and cons of GMO foods and whether you should avoid them. Humans have been altering the genetics of plants for thousands of years through the slow process of cross-breeding between crops. Today, scientists can take a shortcut to modify plants by editing their DNA in a lab setting.

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.

10 Advantages and Disadvantages of GMOs

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:.

Genetically modified GM foods are organisms that have had new genes added to themselves from other organisms. Being around since , they are produced in a way that is very similar to genetic engineering. 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. Some people arrogate that this technology will help those in the agricultural industry decrease the amount of wasted crops and foods.

What are the pros and cons of GMO foods?

За десять лет их знакомства Стратмор выходил из себя всего несколько раз, и этого ни разу не произошло в разговоре с. В течение нескольких секунд ни он, ни она не произнесли ни слова. Наконец Стратмор откинулся на спинку стула, и Сьюзан поняла, что он постепенно успокаивается.
