Genetically Modified Crops Genetically modified food and agricultural biotechnology have generated a lot of interest and controversy in the United States worldwide. Some like the technology’s benefits while others raise questions about environmental and food safety issues. Crop varieties developed by genetic engineering were first introduced for commercial production in 1996. Today, these crops are planted on more than 167 million acres worldwide. U. S.
farmers are by far the largest producers of genetically modified (GM) crops (6) (8).
Genetically Modified Crops are foods that have had a gene extracted from a living thing, which has been placed into a different food by a scientist. This technology can be used to produce new varieties of plants or animals more quickly than conventional breeding methods. Also to introduce traits not possible through traditional techniques. There are two main types of GM crops that are in commercial use around the world. These are either crops that have been developed to be resistant to certain crop pests, or crops that have been developed to be resistant to a particular herbicide (weed killer) (5).
Genetically Modified Crops are made for many different purposes, the main purpose being to create a food able to survive being sprayed with harmful chemicals like pesticides and herbicides. Other purposes are to make food stay fresher for longer, to kill pests, to produce more of the crop and to experiment with taste and quality. The most common foods are maize, cotton, tomatoes, potatoes, corn, canola, soybean and sugar beet (6).
The Term Paper on The Good, the Bad, and the Genetically Modified Organisms
I am a food lover. I live to taste new food items, try new recipes, and experience the wonder of food. For me, ingredients are more than just a step in the process. Ingredients need to be of quality and need to be as fresh as possible. They are the difference between a mind altering eating experience and a boring or even distasteful meal experience. With that being said; we have now engineered ...
Gene Technology is one of the types of modern Biotechnology.
It is the use of living things to make or change products, such as the foods we eat (Melcer 2).
The first genetically modified crops to be sold in the USA were tomatoes, which were modified so they wouldn’t go soft so quickly, then soy beans and oilseed rape, which gives margarine and oils. They were modified to survive certain herbicides and weed-killers, then maize and cotton were modified to carry a poison that kills pests and protects crops against damage. Potatoes were also some of the earliest vegetables to be modified (7).
Genetic modification is an issue which arises every day, although people are not always aware of it. At the moment there is a lot of debate whether GM foods are good or bad. GM Crops are affecting society in many of the foods that we buy (5).
Some of the disadvantages of Genetic modification are that most food manufacturers are unable or unwilling to provide information on whether or not their products contain GM ingredients.
GM crops can contaminate other crops simply by pollen being blown by wind from one field to another. Sometimes GM crops have allergenic effects and a loss of nutritional value. Also new viruses could evolve from the mass production of GM crops (6).
The United States accounts for nearly two-thirds of all biotechnology crops planted globally. GM food crops grown by U. S.
farmers include corn, cotton, soybeans, canola, squash, and papaya. Other major producers of GM crops are Argentina, Brazil, Canada, China, and South Africa. Soybeans, canola, soybeans, and cotton are the primary crops being modified in these countries (7).
Worldwide, about 672 million acres of land are under cultivation, of which 25 percent or 167. 2 million acres consisted of GM crops in 2003. Since 1996, the United States has consistently planted more GM crops than any other country, with 105.
7 million acres supporting GM crops in 2003. Argentina is the next largest producer, with 34. 4 million acres, followed by Canada with 10. 9 million acres, Brazil with 8. 4 million acres, China with 6. 9 million acres, and South Africa with 1.
The Essay on Herbicide Tolerant Crops Genetically Engineered Food
Patrick Donahue Nats 104 3-9-00 Herbicide-Tolerant Crops Crop management is a vigorous activity that changes as technologies are developed. Now that were in the new millennium, we are finding new and enhanced ways to improve things that effect us in our everyday lives like, industrial pollution, car pollution, waste management, and also the advancement in herbicide-tolerant crops. Much advancement ...
0 million acres in 2003. Together, these six countries grew 99 percent of the global GM crop area last year. Australia, Mexico, Romania, Bulgaria, Spain, Germany, Uruguay, Indonesia, the Philippines, India, Columbia, and Honduras also planted significant acreage in GM crops in 2003. The number of farmers planting GM crops has also increased over the past three years.
In 2000, 3. 5 million farmers planted GM crops. That number has nearly doubled, to an estimated total of seven million farmers planting GM crops in 2003. More than 85 percent of the farmers who planted GM crops in 2003 were resource-poor, including Chinese and South African cotton growers (7).
In the United States manufacturers of Genetically modified crops are required by law to label their product accordingly. The consumer should have the right to make an informed decision about what they are eating. In other countries worldwide labeling is not required. For instance in the Philippines there is no labeling. When consumers buy their food they have no way of knowing what pesticides are in their food.
In the United States the manufacturer is at fault for when GM foods are not labeled but in European countries it is the retailer who sells the product. Some studies have shown that food that is prepared the conventional way are more likely to be 20 to 30% more expensive than those which are modified (Ambrose 1).
All over the world there are concerns about Genetically Modified Crops. Some studies prove that they are perfectly safe, however, other sources say that the manufacturers are hiding information from us. Consumers want to know what they are eating so labeling is very important. Some consumers say that they do not mind eating products made from GMO they would just like to be notified if they are modified.
Countries all over the world are trying to test whether or not GMO are safe once and for all (Quick 3).
Releasing a GMO onto the market requires a few steps to be completed. The dossier must provide information on the nature of the GMO, how it has been modified, the precise nature of the research program proposed, where it will be released and how the release will be monitored. The applicant must also supply information for evaluating foreseeable risks, whether they are immediate or delayed, from the release of the GMO (4).

"Debt repayments divert money away from basic life-saving health care in the world's poorest countries. The UN estimates that if funds were diverted back into health and education from debt repayment, the lives of seven million children a year could be saved. That is 134, 000 children a week." In today's global village one cannot ignore the other eighty percent of the world that lives in poverty. ...
While there are many countries that are growing GM crops, there are currently no GM crops being grown in the UK. In recent years GM crops have been grown for research and development purposes at a number of sites.
The main example of this has been the Farm Scale Evaluation (FSE) GM crop trials. No GM crops are expected to be grown commercially in the UK before 2008 at the earliest. For the future, the only crops likely to be proposed for cultivation in the UK are commodity crops; for example oil seed rape – not horticultural products like fruits and vegetables (4).
During the next few years GM crops will be carefully studied and hopefully a conclusion will occur.
