    7 billion people live on this Earth with hungry bellies, only 40% of the population are farmers. Farms have acquired a hardship to feed all the hungry mouths. So, like the world changes as do the way of farmers. Many people thought farming was a dying art until foods met with science and technology, giving the world genetically modified foods. Is this harmful to the world? If so, why have people been using it so long? Farming dates back to the beginning of time. Plants and animals genes have been

    writes. “Super weeds could lead to "bio invasions," displacing local diversity and taking over entire ecosystems.” Monsanto and a former life sciences organizations created a method of injecting the toxin producing gene from the bacterium Bacillus thuringiensis (BT) into corps. This specific BT gene harvest a toxin that restricts insects, and the genetically engineered BT plants and therefore, able to create their own

    pesticides in reducing Corn Borers. There exist many benefits and drawbacks to the use of Bt corn. Bt corn is a form of corn where Bacillus thuringiensis, a bacteria, is transplanted into the corn as a form of pesticide. Ric Beesin, an entomologist at the University of Kentucky, claims “A donor organism may be a bacterium... In the case of Bt corn… Bacillus thuringiensis, and the gene of interest produces a protein that kills Lepidoptera larvae… Growers use Bt corn as an alternative to spraying insecticides

    crop; therefore, cotton has been genetically modified to produce specific toxins for insect tolerance, this is called BT toxin. BT cotton is a type of transgenic cotton containing a protein induced from the gene of soil bacterium named as Bacillus thuringiensis (BT). Genes encoded for proteins were incorporated into cotton plants by Monsanto, an American agricultural biotechnology corporation. In 1980, Monsanto identified and extracted BT genes, the gene encoding for BT protein (Cry1Ac) was successfully

    Too When It Comes To BT Cotton? By: Razan Alhaj, Jaycee Nguyen, Sarah Ronquillo, and Sharissa Soriano March 24, 2014 Worldwide – As many may know, BT Cotton is a cotton plant that has been genetically modified to produce a toxin known as BT (Bacillus thuringiensis), hence the name BT Cotton. Normally cotton is grown within the small green buds of the plant, known as the boll, and once ripe, the bud blossoms to reveal the cotton fibers, but many farmers struggle to protect their cotton from insect invasion

    affected our way of living. The assumption that GMOs are causing a variable of health problems holds no credible scientific evidence. There is proof, however, in developing countries like India genetically modified crops like cotton containing bacillus thuringiensis, or Bt have resulted in higher yields and profits for the poor farmers. Thanks to its resistance to bollworm farmers using Bt cotton can save money on herbicides, saving more money for food and education. Many of the GMOs have been developed

    Insecticide resistance is defined as a genetically-based decrease in susceptibility of an insect population over time, in response to long-term exposure to an insecticide. There is a shift in the genetics of a population that allows individuals within a previously susceptible population to survive. Resistant populations inherit traits that reduce their susceptibility to individual insecticide. In other words, pests develop a resistance to a chemical through natural selection: the most resistant

    Genetically modified organisms (GMOs), organisms that have been genetically altered that cannot occur in nature, change many aspects of a standard modern diet. In the developed world, 80% of all foods consumed contain GM ingredients. Although some countries have begun to label GM foods, 135 countries are still in the dark as to whether or not what they are eating is genetically modified. GM crops can add more nutritional value to a diet, because foods can now be engineered to contain more essential

    Throughout the twentieth century, farmers use techniques to strengthen plants to ensure greater food productivity. One of the early forms of genetically modified foods are hybrid plants. By breeding two of the strongest plants together, scientists are able to obtain a stronger offspring. As science progressed with Watson’s discovery of DNA, biologists were able to identify certain genes that would be desired. Today, foods are genetically modified through experiments with the insertion of genes administered
