Genetically modified foods, harmful or helpful The term genetically modified foods (GM foods) is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology technique. Compared to normal food, the benefits of GM foods is very obvious. Such as GM food can reduce damage to crops by chemical pesticide, herbicides and improved crops nutritional content. Now, planting genetically modified food has become very popular in the world. Although the genetically modified foods have many advantages than conventional foods, but we also cannot ignore the fact that GM foods also bring to a lot of problem.
Bt toxin and Glyphosate Paragraph 1: Soybean is known for the benefits of our health and it contains 43 percent of protein. So soybean needs to be produced in the amount of population in the world. To do this, the yield will needs to be maximized to grow and produce more soybean. However, according to the WWF, by “the rapid expansion of soybean cultivation, it threatens wildlife and biodiversity. Also damaging water reserves and soil quality.” In the world, scientists try to find the ways of Biotechnology for an harvesting more soybean, with not maximizing yield that causes bad influences to the environments.
What Genetically Modified (GM) Foods’ Risk Is What Genetically Modified (GM) Foods’ Risk Is Abstract In the present day, by the developing of agricultural technology, the Genetically Modified (GM) Foods have become more and more popular. Many countries’ peasants would like to plant GM foods instead of some original foods, because the GM foods have these advantage, rest resistance, disease resistance, Cold tolerance and some else. However, as a new and developing technology, the GM foods still have a lot of risks, like reduced effectiveness of pesticides, gene transfer to non-target species, human health risk, etc. Moreover, if we do not pay attention on it, in future, it is likely to threaten the living environment or even human life. Therefore, we cannot ignore these risks to harm to our health and the environment.
Life Science Michael Garcia Virtual Lab #1 8/30/14 Dependent and Independent Variables Introduction The use of transgenic corn crops has increased over the years. This type of modified corn is in use because of its resistance to pests like the European Corn Borer (ECB). In this experiment, the effect of ECB infestation on corn crop yields will be examined. Two varieties of transgenic and two varieties of non-transgenic corn seeds will be used to see how well they weather the infestations. The independent variable for this lab is the ECB infestation, and the dependent variable will be the yield of corn.
For its part the New World provided a host of sustaining crops that could be cultivated in Europe, such as potatoes, maize (corn), tomatoes, squashes, and varieties of beans; foods that appealed to European tastes, such as cacao (chocolate), avocados, and chilies; and other products that served a growing demand, such as tobacco, indigo, and cotton. Few New World animals of consequence migrated to Europe during this period, but possibly the venereal disease syphilis first reached Europe from the Americas. Before and since the publication of Crosby’s work, students of European expansion have not neglected his factors but have also pointed to the interregional migration of people and their cultures and metals (iron from Europe and silver and gold from the Americas). The student must discuss the impact of the Columbian exchange on the population and economies of Europe. For example, this might include the effects of transferred food crops on diet and population growth in Europe, potatoes and corn as factors in the agricultural revolution, the economic effect of cane sugar and tobacco production on European economies (e.g., wealth produced by the New World plantation systems for Europe, the stimulation that agriculture gave to international commerce and later industrialization, the need for large-scale labor for sugar
20061962 Wed The purpose of this study is to test whether or not organic foods have more health benefits and are safer than conventional foods. The word organic refers to how farmers grow and process agricultural products. Farmers use nonconventional methods to fertilize, control weeds and to prevent disease in livestock. This study included seventeen studies in humans which carefully studied the biomarker and nutrient levels in serum, breast milk, semen and urine. The participants involved in this study were tested for pesticide levels.
------ The Benefits of Genetically Modified Foods ------ Today, 91% of major plant varieties grown in the U.S. have been created in a lab. (Center for Food Safety) These plants are genetically modified (GM), and while often ignored by the public, have generated much controversy over their effects on health, the environment, and the economy. First grown in the 1990s, GM foods have had their genes modified to produce desirable traits, such as herbicide resistance and protection from pests. This is done by splicing genes from another organism with desirable traits into a different seed. For example, traits from a plant rich with nutrients could be inserted into another seed, giving that plant more nutrients than it would normally would have.
Genetically Modified Organism (GMO) is one of the most important issues from around the world. GMOs are special organisms in which the genetic material has been altered for improvement productivity and product quality. GMOs have raised concerns over their own beneficial in that they are resistant to disease, help humans suffering from famine, produce greater yields, and improve the nutrition of foods. Having foods is very important to human life to maintain good health and to survive. It is not secret that GMO-ed foods have spread out rapidly to the whole world.
Technological advancements in the scientific field have led to the advent of genetic engineering, including the genetic modification (GM) of food that may hold the key to the solution of many existing problems like food shortage, world hunger and genetic diseases. Uzogara (2000) state that the intentional attempt to alter the genetic make-up of plants or animals is known as genetic modification. Scientists have shown the potential benefits that those genetically engineered crops can bring about such as increased shelf-life in Flavr Savr Tomato and pest-resistant Bacillus thuringiensis (Bt) corn, which are said to benefit the producers. From the consumers’ point of view, what matters most is the health benefits that genetically engineered crops will bring about, which wild-type food crops may not be able to do.
Many large and small scale companies are involved in trade of these food items. In many countries government operates trade of these products. Genetically modified food items are agricultural goods or livestock that is modified by means of biotechnology into better quality food items. These GM food items do have some drawbacks such as harm to environment and human health. Not all the countries approve GM food products.
