Genetic engineering in plants pros and cons Rating:
Genetic engineering is the process of altering the genetic makeup of an organism by adding, deleting, or modifying specific genes. This technology has been applied in various fields, including agriculture, where it has been used to create genetically modified (GM) plants with desired traits. GM plants have the potential to address a range of challenges faced by the agriculture industry, such as crop diseases, pests, and changing environmental conditions. However, the use of GM plants has also raised concerns about their potential risks and ethical implications. In this essay, we will discuss the pros and cons of genetic engineering in plants.
One major advantage of genetic engineering in plants is that it allows for the creation of crops with improved qualities. For example, GM crops can be made resistant to pests, diseases, and harsh environmental conditions, such as drought or extreme temperatures. This can lead to higher crop yields and lower costs for farmers, as they do not need to use as much pesticides or irrigation. GM crops may also have a higher nutritional content, such as rice that has been genetically modified to contain more vitamin A (also known as "Golden Rice"). This can help address malnutrition in areas where certain nutrients are lacking in the diet.
Another potential benefit of genetic engineering in plants is that it can help reduce the environmental impact of agriculture. For example, GM crops can be designed to use less water or fertilizers, which can help reduce the pollution caused by these substances. GM crops may also be used to restore degraded land or to create new habitats for wildlife.
However, there are also potential drawbacks to the use of GM plants. One concern is that they may have unintended consequences for the environment and human health. For example, GM crops may cross-breed with wild plants, leading to the spread of modified genes into natural ecosystems. This could have unknown impacts on biodiversity and the balance of ecosystems. There is also the possibility that GM crops could be harmful to humans if they contain allergens or toxins that were not present in the original plant.
Another concern is the ethical implications of genetic engineering in plants. Some people argue that it is unnatural and goes against the fundamental principles of biology. Others worry about the potential for GM crops to be used to control the global food supply or to benefit large corporations at the expense of small farmers. There are also concerns about the potential for GM crops to exacerbate social and economic inequalities, as they may only be accessible to wealthier countries or individuals.
In conclusion, genetic engineering in plants has the potential to bring significant benefits, such as improved crop yields, higher nutritional content, and reduced environmental impact. However, it also raises concerns about potential risks to the environment and human health, as well as ethical implications. As with any technology, it is important to carefully consider the potential pros and cons before making decisions about its use.
Pros and Cons of Genetic Engineering
It also gives us a chance to create products that have a longer shelf life to reduce waste in the agricultural industry. Have you ever taken the pollen from one flower and given it to another? However, there are no known cases of these methodologies being used to create a new organism. Modified corn, for example, can be used for specific purposes, such as animal feed, ethanol, or larger cobs for human consumption. One of the first ways that we began to benefit from this approach was to use bacterial cells in a way where they could begin producing human insulin. But the bacteria and viruses evolve to the resistance of GMO as well. This gives farmers the ability to expand beyond the traditional locations and use the empty lands for other purpose.
While pesticide helps keep other organisms from taking crop harvest, it has also added chemicals into the food that we consume; chemicals that should not be inside of us. The two main types of GMO crops in use are bioengineered to either produce their own pesticides or to be herbicide-tolerant. What does GMO stand for? It can create less nutritional value in some foods. Advantages Of Genetic Engineering 1044 Words 5 Pages Genetic engineering in healthcare Genetic engineering is a form of applied biology, often used to change a person's genome by using biotechnology. Farmers can rely on genetic engineers to develop crops that will withstand heavy frosts, extreme temperature swings, and dry, salty soils.
13 Advantages and Disadvantages of Genetic Engineering
One specific gene is located and copied from thousands of genes, this is called gene cloning. Generated crops can increase production capacity and nutrient capacity. Brazil nut gene in transgenic soybeans. I Enhances biodiversity by allowing weeds to intuition growing for longer thus providing nutrition for animals. It caused harvests in the Bordeaux region to shrink by 40% in a single year — and that was for non-genetically engineered products.
In artificial selection, scientists breed only individuals that have desirable traits. Firstly it allows for faster growth rate. A company could refuse to let anyone use their product as well, theoretically cutting off an entire industry at its knees to advance its own agenda. Figure 5: Pest-resistant Crops. Read on for some of the most important pros and cons of genetic engineering for the field of environmental science and sustainability. Almost everything in this field revolves around DNA and its numerous properties. This process can even be used to reduce the levels of food spoilage which occur because the food products last longer on store shelves.
The farmer has to pay royalties to the biotech company. For government agencies, genetic engineers are also required. GM crops add to the tendency of modern chemical agriculture to undermine the autonomy of farmers and turn them into tractor drivers or machine minders for large transnational corporations. Genetically engineered commodity crops, under the influences of patent protection, have become overwhelmingly dominant in our food supply already in the United States. Prickly pear in Australia.
Identity Preservation Systems are being put in place, verified by DNA analysis, to ensure that GM and non-GM supplies are kept separate. The goal of genetic engineering is to create a better world by boosting the positive traits that every life form has at the cellular level. Animals modified for greater milk production might have a shortened lifespan so that the farmers suffer greater livestock. Many of the modern approaches in this field have created temporary benefits at best. It could be used for abusive purposes. For this purpose, using mice in order to examine the effects of genetic manipulation on obesity, cancer, heart diseases and other serious conditions is common practice in nowadays scientific work.
I More profit for the farmer, seed producer and biotech company shareholder. United States Department of Agriculture Economic Research Service, "Recent Trends in GE Adoption," ers. I GE introduces unpredictable toxic or allergenic effects into food plants e. We can grow enough food to produce feed for livestock that support our modern nutritional food profile. This can result in class supremacy and discrimination against the common man.
Bacteria contain vectors called plasmids, which are small circular pieces of DNA within the bacteria. It is estimated that a lack of this vitamin causes up to 500. This knowledge and technology can be easily abused. Although improved crop yields can be engineered by genetically modifying plants, there s ecological concern over whether these plants are likely to persist in the wild in the event of dispersal from their cultivated habitat. This field has proved to be a boon to humankind for its numerous advantages that can be perceived in the field of technology, agriculture, medicine etc. Unfavorable to Genetic Diversity Genetic engineering can affect the diversity among the individuals. The human growth hormone previously acquired from cadavers and bio-engineered insulin previously acquired from cows or sheep are two major examples of genetically engineered drugs.

These processes can cause dramatic changes in the natural makeup and characteristic of the organism. Even though our predictive qualities in this field are increasing, we still do not know what happens when we artificially advance the evolution of life. A series of chemical and DNA tests confirm the weeds in farmer Tony Heather's field near Semitism are resistant to Unsustainable based on greed not need. Although immunosuppressants are effective at what they do, this medication can also put people at a higher risk for certain illnesses and infections. It would reduce the cost of food for the average household.
