Genetically modified foods

Genetically Modified Foods

By

Thomas Confrey


World hunger on the rise

World Hunger on the Rise


History of genetic modification

History of Genetic Modification

  • Happening since the Neolithic Revolution

  • Three Common Methods

    • Selective Breeding

    • Combing/Hybridizing Species

    • Exploiting Natural Mutations


New techniques using dna

New Techniques using DNA

  • Modern genetic modification involves tranfer of DNA

  • Cisgenesis – genes transferred from similar species

  • Trangensis- genes transferred from dissimilar species


Risks from gmf

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


Risks cont d toxic crops

Risks Cont’d: Toxic Crops

  • GM Plants designed to keep bugs/animals away

  • GM Plants take up more chemicals including heavy metals


Environmental issues

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


Attitudes towards gmf

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


Slippery banana

Slippery Banana?


Genetically modified foods

FDA

  • Currently Genetically Modified foods do not need special labels


Fda approved gmo foods

FDA Approved GMO Foods


Conclusion

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
