The Effects of Genetic Engineering on Agriculture
Agribiotechnology is the study of making altered agricultural products. Agribusiness is trying to alter the genes of already existing products to try to enhance the biocompetitiveness and adaptability of crops by enhancing plant resistance to drought, salinity, disease, pests and herbicides. They are going to try to enhance their growth, productivity, nutrient value, and chemical composition. The old way of doing this was through selective breeding, special fertilizer, and hormones. This seems now somewhat outdated with today’s technology. Genetic engineering comes with many downfalls. Increased production through genetic engineering could exhaust nonrenewable resources more

This is a common bacterium on plants that causes frost to form on them. The lipoprotein coating of this bacterium is blown from the plants and soil into the atmosphere. Once in the upper atmospheric regions, these particles act as nuclei around which water collects and freezes to form ice. Some scientists consider this process absolutely essential for rain to fall. Genetic engineers are working on a strain of P. syringae that would not form frost on plants. Some scientists are concerned that these strains could conceivably cause serious climatic perturbations that inhibit rainfall and cause drought. Farmer’s fields are not the only places that are threatened. Scientists are looking for a way to destroy lignin, an organic substance that makes trees rigid, by use of a genetically engineered enzyme. They believe that it would be of use to clean up the effluent form paper mills or for decomposing biological material for energy. This poses a threat to forests because it could destroy massive amounts of them by eating away their lignin. We could end up with no trees. Engineers could try to create organisms with a “suicide” gene so they only live for a very short time, but they would be alive long enough to do damage. These engineers and businesses, like Pioneer, Sandoz, Imperial Chemical Industries, Dow, Ciba-Geigy, Monsanto, Upjohn, Elanco, and Pitman-Moore to name the leading corporations in agribiotechnology, don’t understand the impact that these engineered
Genetic Engineering has a multiplicity of uses in agriculture. It can be utilized to increase crop output, resistance to pest and diseases, and enhanced growing conditions. Sagoff states “Genetic engineers can help peasant societies by engineering plants and animals to stand up to the challenges of local conditions, such as blights that affect yams and other traditional crops” (14). The article “Biotechnology and Agriculture: The Common Wisdom and Its Critics.” by Sagoff. Discusses how genetic manipulation of crops would be of major benefit in developing countries, primarily because said countries can 't grow enough food to suffice the populous. Genetic manipulation of plants can make food easier to grow in these countries.
The concept of intentionally altering an organism’s DNA in order to produce genetically modified organisms (GMOs) has been critically analyzed by both science and the mainstream media in the last decade. However, the genetic modification of organisms is not a recent innovation as humans have been modifying organisms for over 30 000 years (Rangel, 2015). Back then, breeding through artificial selection was the most prominent method of genetic engineering. Organisms with the most desirable traits would be bred together in order to create a new generation of superior organisms. Throughout the centuries, the developments in science and technology have resulted in new methods of genetic engineering. Now, genomes can be spliced in order to insert or remove genes. It has essentially come down to a copy and paste process with genes from animals being inserted into plants as the common practice.
Some worry that the farmers will become dependent on corporations that produce these genetically modified organisms. Others worry about the consumption of these modified crops and the affects they may have on health, or that these plants may harm the ecosystem. One expert worries that the focus on genetic tinkering draws attention away from safer methods that also provide more produce, such as crossbreeding. However, if the efforts to create crops resistant to drought are successful, humans will be able to resist and adapt to climate change better. While it is important to learn to adapt to climate change, humans should also make an effort to stop and prevent it and its
Biotechnology provides farmers with tools that can make production cheaper and more manageable. For example, some biotechnology crops can be engineered to tolerate specific herbicides, which make weed control simpler and more efficient. Other crops have been engineered to be resistant to specific plant diseases and insect pests, which can make pest control more reliable and effective, and/or can decrease the use of synthetic pesticides. These crop production options can help countries keep pace with demands for food while reducing production costs. The USDA also mentions the fact that they are still trying to discover new methods to help the U.S. Often people worry about the negative rumors of what happens to crops when Genetically engineered plants are being grown. Genetically engineered plants are also being developed for a purpose known as phytoremediation in which the plants detoxify pollutants in the soil or absorb and accumulate polluting substances out of the soil so that the plants may be harvested and disposed of safely. In either case the result is improved soil quality at a polluted site. Biotechnology may also be used to conserve natural resources, enable animals to more effectively use nutrients present in feed, decrease nutrient runoff into rivers and bays, and help meet the increasing world food and land demands. Researchers are at work to produce hardier crops that will flourish in even the harshest environments and
Biotechnology is the manipulation of microorganisms, through DNA manipulation and bioprocess manipulation for industrial, health, and food industries. Although, there are many different types of biotechnologies; agriculture is the leading type of biotechnology that has affected humans for thousands of years - and will continue to make a large impact for the future of humanity. What exactly is agricultural biotechnology? Agricultural biotechnology, or agritech, is a combination of tools to improve or manipulate microorganisms, or parts thereof, for agricultural use - such as bacteria resistant, improve crop yield, and the list goes on. Biotechnology, in specifies, agricultural biotechnology has been used for thousands of years. Scientists do not have a specific date as to when agritech was first utilized, but they have concluded that approximately ten thousand to twenty thousand years BC, early humans domesticated plants and animals. Overtime, the desired plants and animals were bred - the desired, and overall better quality plants and animals were selectively bred. Thus overtime, unknowingly
Genetic engineering techniques have been applied to various industries, with some success. Medicines such as insulin and human growth hormone are now produced in bacteria, experimental mice such as the oncomouse and the knockout mouse are being used for research purposes and insect resistant and/or herbicide tolerant crops have been commercialized. Plants that contain drugs and vaccines, animals with beneficial proteins in their milk and stress tolerant crops are currently being developed
For the last several decades, the world has been plagued by widespread starvation and poverty. Economies are failing in numerous countries, and developing nations struggle to feed their inhabitants. As a result of the world’s mounting overpopulation, food has become scarce and resources are rapidly dwindling. However, modern science has provided a solution: agricultural biotechnology. Genetically engineered crops represent the bright future of agriculture. Crops like cotton, corn, and soybeans can have genes inserted or deleted into their cell membranes; this modification facilitates pest and virus resistance, drought tolerance, and even provides nutritional enhancement. Genetically altered crops produce much higher
Back then, farmers relied solely on the plot of soil they owned to produce fruits and vegetables. Farmers often had to deal with the threat of damaged crops from weather changes and insect pests. However, imagine being able to not increase productivity and protecting crops being ruined or eaten. Now, with advancements in technology and genetics, scientists can genetically modify organisms by altering its DNA in a way that does not occur naturally by mating or natural recombination to introduce desired physiological traits (EFFL 235). In 2000, 68% of all genetically modified, GM, crops were grown by U.S. farmers, with soybeans and corn making up 82% of all GM crops harvested in 2000 (Whitman 5). According to the European Food & Feed Law Review, scientists may transfer simple genes from the DNA from one organism into another, and also between non- related species, such as animals, bacteria, and virus to enhance desired traits (4). The use of genetic engineering was first introduced to aid farmers in an alternative other than using pesticides. Soon after, enhanced traits that improve nutrition were inputted into plants to increase nutritional value. Although the genetic engineering of GM food may create superweeds, GM food should be encouraged since it decreases the need for pesticides, increases food supply, and improves the nutrition of food.
Dr. David Suzuki, a well-known Canadian geneticist, had a powerful message when it came to genetically modified organisms: “Anyone that says, ‘Oh, we know that this is perfectly safe,’ I say is either unbelievably stupid or deliberately lying” (Smith). Agricultural companies have spent several years and millions of dollars displaying GMOs on a pedestal made of deceitful promises. Because of this, the general public has adopted several misconceptions as facts, believing that these altered organisms will increase crop yields and reduce the use of pesticides. World citizens must open their eyes to see past the positive claims of large corporations because genetically modified organisms, or GMOs, have an undeniable dark side.
Monsanto is today a well-known company, and have both been commended and condemned for what they accomplished as a firm. Expanding the production into industrial chemicals has met a lot of criticism throughout the years (Monsanto Company, 2015). At the same time, in 2014 they were able to increase crop yields by 22 percent, reduce pesticide use by 37 percent, and increase farmer profits by 68 percent. (Bennett, 2014). Meaning, they have managed to use technology that allows developing countries to use less resources and to create even higher crop yields (English, 2014). However, it has been achieved on the expense of a controversial product, which is a major subject in todays view on how to maintain a sustainable environment, namely the genetically
Most public concern has been focused on human health and safety regarding the use and consumption of these foods, but potential environmental impacts are important to consider as well. Many varieties of genetically engineered crops are intended to decrease the need for chemical pesticides and fertilizers, but the scope of environmental impacts does not stop at chemical usage. Common concerns about GM crops include the effects of cross-pollination, so-called “genetic contamination,” and the escape of GM crops from cultivation and their interactions with native species. Conversely, the environmental benefits of GM crops range from reducing dependence on chemical pesticides to the ability to treat polluted soils with bioremediating plants (Ford, 2004).
In the other hand GM critics worry that transgenic crops could harm wildlife and cause lasting damage to fragile food chains. What will happen if GM farming practices wipe out weedy plants that some bird’s species rely on for survival? Or if insects that are important
Among the millions of species that inhabit the planet, only twenty species provide ninety percent of the human food supply (Montgomery 2000). Since the introduction of genetic engineering, however, livestock and crops have a more productive future. Transfer of engineered genes from organism to organism occurs through hybridization, conjugation, and transformation in microorganisms. By the substitution of genes into agricultural species, biodiversity can flourish to improve social and economic development. Although methods of gene and DNA implantation quickly develop advanced products, even precise genetic alterations do not ensure that the environment will remain balanced or that changes in
Advantages and Problems of Genetically Modified Agricultural Crops Genetically Modified food (GM) is most commonly used to refer to crop plants created for human or animal consumption, using the latest molecular biology techniques. These plants have been modified in the laboratory to enhance desired traits such as increased resistance to herbicides or improved nutritional content. Genetic engineering can create plants with the extract desired trait, both accurately and rapidly. For example frost can destroy sensitive seedlings, an antifreeze gene from cold water fish has been introduced to plants such as tobacco and potatoes, and with this anti freeze gene these plants are able to tolerate the
One industry that plays a vital role in our society is the agricultural industry. The agricultural industry is responsible for the growth of all our valuable crops such as cotton, corn, fruits, other vegetables etc. These crops are planted and then gathered to be sold to consumers. These primary resources are important to our daily lives because they are valuable sources of food and clothing, which are highly needed for our survival in life. Over time, it has been discovered that genetic engineering in plants can be an alternative way to “alter a plant’s genetic makeup” (Nutrition & Weight Control for Longevity, 2005). Why would we want to alter a plant’s genetic makeup? Well, the main reason is to “produce a desired characteristic or weed out an undesirable one” of a plant (Nutrition & Weight Control for Longevity, 2005). Approximately “75% of processed foods contain at least some genetically engineered ingredients” (Nutrition & Weight Control for Longevity, 2005). In the United States, soy beans, cotton and corn are among the many crops that are genetically modified to “resist common herbicides” (Nutrition &
