  1. Genetically Modified Foods By Thomas Confrey

  2. World Hunger on the Rise

  3. History of Genetic Modification • Happening since the Neolithic Revolution • Three Common Methods • Selective Breeding • Combing/Hybridizing Species • Exploiting Natural Mutations

  4. New Techniques using DNA • Modern genetic modification involves tranfer of DNA • Cisgenesis – genes transferred from similar species • Trangensis- genes transferred from dissimilar species

  5. Risks from GMF • Food allergies are a problem for many Americans. (e.g. Soy, peanuts, seafood, etc) • New genetically modified species means infinitely more proteins • Usually, allergies are only discovered after an individual has a violent reaction. • Predicting allergies is nearly impossible

  6. Risks Cont’d: Toxic Crops • GM Plants designed to keep bugs/animals away • GM Plants take up more chemicals including heavy metals

  7. Environmental Issues • Chemical companies often design new pesticides and herbicides, as well as, genetically modified plants, which are “immune” to them. • New pesticides or herbicides can seep into surface and ground water

  8. Attitudes towards GMF • Necessary • World hunger is out of control • Unnatural • Stems from moral/ethical dilemma • Dangerous • Risks outweigh any benefits • An Option • Opinion of the US government

  9. Slippery Banana?

  10. FDA • Currently Genetically Modified foods do not need special labels

  11. FDA Approved GMO Foods

  12. Conclusion • Genetically Modified Foods are not going away • Could be used to eliminate artificial dyes, preservatives and steroids • Still need more research and long-term testing/risk assessment • Fertilizer is a major problem
