Summary Introduction

To explain: The response against genetically modified food critics.

Concept introduction: Genetically modified foods have been made by scientist by introducing certain changes in the DNA or genome of crop plants by using genetic engineering. It is very different from breeding because in this instead of getting random genes, scientists put a desired gene directly into the plant’s DNA.

Genetically modifying seeds to produce herbicide-resistant plants that increase crop yields has revolutionized modern agriculture. However, genetically modified organisms (GMOs) have come under fire in recent years, with consumer groups calling for mandatory GMO labeling on all food packages that contain GMO ingredients. GMO labeling laws have been in force in the European Union and other countries for several years, but the threat to the U.S. food industry is only now surfacing. Although bills requiring GMO labeling have been introduced in many state legislatures, Vermont is the only state where such a law has so far withstood the first round of legal battles from the industry. Leading chemical companies, including Monsanto, BASF, and DuPont, are the world’s largest suppliers of seeds that grow the food that feeds the world. To counter the GMO labeling threat, they now are turning to mutagenesis as an alternative technique to create herbicide-resistant crops. Mutagenesis mimics the…
Examples of GMOs Correctly classify examples of bacteria, plants, and animals that have been genetically modified. Produce biofuels and other chemicals for use in manufacturing Genetically Modified Bacteria Reduce the impact of pest species by either deterring them or killing them Modified to have increased nutritional value by reducing their susceptibility to disease, increasing their rate of growth, and improving the quality of the meat/milk Provide organs for humans for transplantation Serve as models for studying human diseases such as cystic fibrosis Produce enzymes to enhance metabolic pathways to aid in the breakdown of toxic chemicals in the environment Allow organisms to better face environmental challenges such as drought, heat, and high salt content in the water supplies Reduce the number of pest species that are vectors for diseases such as Zika and dengue fever Modified to produce antibodies, vaccines, and enzymes that can be used in the treatment of humans Provide plant's…
Genetically modified organisms (GMOs) are used to create human growth hormone, insulin and clotting factor proteins that are used to treat dwarfism, diabetes and hemophilia respectively. Several crops such as corn and soybean have also been genetically modified in order to facilitate either the management or growth of these crops. Why do you think there is push back or opposition against the use of GM food crops but not in the use of products such as insulin, which is also created using GMOs?
