Pros and Cons of Genetically Modified Foods - 2267 Words

Our ancestors first cultivated plants some ten thousand years ago. They domesticated animals later and then selectively bred both plants and animals to meet various requirements for human food. Humans discovered natural biological processes such as fermentation of fruits and grains to make wine and beer, and yeast for baking bread. Manipulation of foods is not a new story, therefore. The latest agricultural discovery uses genetic engineering technology to modify foods. Farmers and plant breeders have been changing crop plants to improve characteristics such as size, resistance to disease and taste. Plants which grow well, have a higher yield or taste better are selected and bred from. This is still the most widely used technique for†¦show more content†¦Transgenic crops are grown commercially or in field trials in over 40 countries and on 6 continents. In 2000, about 109.2 million acres (442,000 km ²) were planted with transgenic crops, the principal ones being herbicide- and insecticide-resistant soybeans, corn, cotton, and canola. Other crops grown commercially or field-tested are a sweet potato resistant to a US strain of a virus that affects one out of the more than 89 different varieties of sweet potato grown in Africa, rice with increased iron and vitamins such as golden rice, and a variety of plants able to survive extreme weather. Between 1996 and 2001, the total surface area of land cultivated with GMOs had increased by a factor of 30, from 17,000 km ² (4.2 million acres) to 520,000 km ² (128 million acres). The value for 2002 was 145 million acres (587,000 km ²) and for 2003 was 167 million acres (676,000 km ²). Soybean crop represented 63% of total surface in 2001, maize 19%, cotton 13% and canola 5%. In 2004, the value was about 200 million acres (809,000 km ²) of which 2/3 were in the United States. In particular, Bt corn is widely grown, as are soybeans genetically designed to tolerate glyphosate herbicides. Future applications of GMOs include bananas that produce human vaccines against infectious diseases such as Hepatitis B, fish that mature more quickly, fruit and nut trees that yield years earlier, and plants that produce new plastics with unique properties.

Food is our source of nutrition and energy. When we consume food and water, our body breaks food down into tiny particles and sends the nutrients throughout our bodies through blood. This is called digestion. According to science, nutrients are one of the four requirements of life for all human beings. Every day, we are faced with choices about our foods.

Humans have been domesticating plants ever since 11,000 BCE. Scientists have been breeding plants together with traits that are considered beneficial to humans and trying to intensify the traits that help humans survive. By altering the genetic structure directly, scientists can efficiently give it specific traits in a more controlled environment and avoid the hit or miss aspect of naturallyRead MoreGenetically Modified Food - Pros Cons2979 Words   |  12 PagesApril 2012 Genetically Modified Food: World Wide Panacea or â€Å"Frankenfood† to Fear? Never before in history has mankind so masterfully commanded its food chain. Thousands of years ago, much of our species made the leap from a hunter-gatherer level of subsistence to an agricultural society. With agriculture, slowly but surely many modifications were made to plants and animals used and domesticated by us for the purpose of feeding ourselves. New specialized varieties with specific desirable traitsRead MorePros and Cons of Genetically Modified Food Essays589 Words   |  3 PagesPros and Cons of genetically modified food, or GMOs Genetically modified foods are a types of foods that have been genetically changed, to add or get rid of an unwanted trait in a food. For example, seedless oranges. This is a type of orange that is genetically modified (had tits genes changed) specifically so it would grow without seeds. Many foods are genetically modified today. Oranges, corn, tomatoes, potatoes, squash, and many others have had their genes changed.

For example, the first time a person tastes a delicious juicy piece of prime rib or a delightful hamburger with cheese and ham, his world is never the same. However, since the beginning of the twentieth century, the production of food has been supplemented by science. This has triggered an angry dispute between the people who support the advances of biotechnology and people who love nature. In order to understand the controversy, we have to know the meaning of genetically modified foodsRead MoreThe Pros And Cons Of Genetically Modified Foods1809 Words   |  8 PagesAs the spread of commercialized genetically modified foods (GMF) products rise, the number of people exposed to genetically modified foods incline globally. The term genetically modified foods can be used interchangeably with transgenic foods, genetically engineered crops (GE) and Recombinant DNA technology and therefore defined as the enhancement of foods in which a gene of interest from one organism is extracted and inserted into the target organisms. (1) The genes of interest may be cells fromRead MoreEssay on Pros And Cons of Genetically Modified Foods3322 Words   |  14 Pagespossible benefits, from helping farmers, to improving foods, to helping the environment, to helping sick people. Genetic engineering may even one day be used to help solve world hunger. However, it also has its dangers and risks, which need to be considered along with its benefits. The fact that not everything is known about genetic engineering, and that large corporations use it to make a profit, is scary to many people. The recent technology of genetically engineering crops, plants, and animals, whichRead MoreThe Pros And Cons Of The Labeling Of Genetically Modified Foods918 Words   |  4 Pagesthan 70% of packaged foods contain GMO in the US market, there are no regulations to mandate the labeling of GM foods by the US government. Currently, the US federal government does not require any mandatory labeling of GM foods, unless the nutrition of GM foods has been changed or some toxins and allergens have been added to the GM foods (McLure). According to the U.S. Food and Drug Administration (â€Å"FDA†), there are also no mandatory programs to regulate foods from genetically engineered (â€Å"GE†) plantsRead MoreGenetically Modified Foods, Pros and Cons persuasive essay.1883 Words   |  8 Pagesoverpowers the bad. Many experts argue that Genetica lly Modified foods are actually beneficial to, not only people, but animals, plants, and the world overall. Some experts even state that, not only are they beneficial, but that they also protect the environment and aid food productivity. Most farmers actually recommend GMO’s because they are easier to grow, maintain, and tend to be more profitable; however, countless other experts have come to realize that GMO foods are untested, unsafe, and unhealthy.Read MoreHow Is Foods Be Easily Modified?1042 Words   |  5 Pages How can foods be easily modified? Intro: In this essay, we will be talking about how foods can be easily modified (GM foods), how they can affect other people, and to see if it is safe to eat them. Body: As if you did not know, GM foods stands for Genetically Modified foods. That means that scientists take and copy the DNA from an organism (ie; a watermelon), and then they put it in with another organism (ie; a corn), which results the [modified] organism to be in the same colour as the copied
