    • GENETICALLY MODIFIED ORGANISM
    • A GMOis a genetically modified organism (also called "genetically engineered"): a plant, animal, or microorganism that is created by means that overcome natural boundaries. Genetic engineering involves crossing species that could not breed in nature.
      • was first used years ago to designate microorganisms that had genes from other species transferred into their genetic material by the new techniques of "gene-splicing."  Applied to crops, the term refers to any genetic plant type that has had a gene or genes from a different species transferred into its genetic material using accepted techniques of genetic engineering, and where such introduced genes have been shown to produce  a gene product (a protein).
      • This process of moving genes into a new species and getting them to function is known as transformation.  In a real sense, all of the crop cultivars that we use are "genetically modified," in that they were bred to be more productive, more resistant, or produce better or different quality of product than did previous cultivars. 
      • Such changes, which have been going on ever since crops were domesticated, involve the addition of genes over time, but such additions are with few exceptions from the same species, or at least the same genus.  Such changes also include such things as mutations, even those induced on purpose, as long as they were done within the genus.
    • ADVANTAGES
      OF
      GMO
      • Modified to make them more resistant to unfavorable conditions.
      • Produce higher yields.
      • Use less fertilizers
      • Use lesser water
      • Pest resistant
      • Herbicides tolerance
      • Increasing food supplies in correlation with an increasingly world population.
      • Solves major human problems such as food and fuel scarcity.
      • Stress and pest resistance.
    • DIS-ADVANTAGES
      GMO
      • Potential Allergic reactions to proteins that have been spliced in.
      • General apprehension from un educated public.
      • Changes in Market Values of certain products due to surplus.
      • Harmful to environment
      • Harmfulto humans
      • Give rise to “super weeds”
      • “Super weeds” dominate the field at affect maiin crops.
      • Genes from the genetically modified food could be transferred to the pests with can make them become resistant to them pesticides at the pesticides become useless.
    • REASONS
      WHY I AM
      PRO-GMO
      • They have the potential to make difference in the lives of populations around the world that are struggling to food security.
    • It is
      beneficial
      and safe
      because:
      • The genetically engineered bacteria are used for waste treatment and cleaning the environment.
      • Genetically engineered bacteria, plants, or animals can produce hormones and antibiotic.
      • No one has been poisoned by a genetically modified plant.
      • And for the farmers GMO made to have pest resistance and high nutrient uptake efficiency. When pest resistance is encoded resistance into plants genome, then the farmer has less necessity for pesticides. This leads to decreased expenses for the farmer, decreased pesticides runoff into waterways, and decreased environmental toxins.
    • Much of the fertilizer that is applied by farmers typically runs off into waterways as well, causing numerous environmental problems that can lead to human health problems, with decreased use of pesticides and fertilizer, there is also decreased use of the fossil fuels that are burned in the manufacture of these products. Not only do farmer in developing countries prefer not to pollute their environments, but they also simply cannot pay the cost of these polluting pesticides and fertilizers.
