  • There are some misstatements in this pro-gmo brochure, including that GMO's lead to reduced pesticide use. Actually, rates increase with most gmo crops. The Canadian gov't found that after 13 yrs, gmo crops actually had lower yields, were much less nutritional, used higher amounts of poisons “Thirteen years ago when GM soya and rapeseed was introduced in Canada (and in the US) the Corporations and Government told farmers that GM would increase yields, be more nutritious, use less chemicals, and feed a hungry world. Now we will always have a sustainable agriculture, they claimed. The Canadian Department of Agriculture figures states canola yields have decreased at least ten percent and soya at least fifteen percent [4], but worst of all, farmers are using three to five times more chemicals because of the GM superweeds that have developed. The reality is that the nutritional content of all crops are down fifty percent of what they were before GMOs were introduced and now we have less yields and more chemicals used, exactly the opposite of what Monsanto promised.”

Genetically modified food powerpoint

  1. 1. Genetically Modified Food BENEFITS & RISKS -BY- KYLE MOE
  2. 2. Breakfast?
  3. 3. Overview Common genetically engineered crops/animals The origin of genetic engineering Top three main areas of controversy surrounding issue Concluding statements
  4. 4. The top threegeneticallyengineered cropsbeing produced onU.S. soil- Soybeans atestimated 87-90%- Cotton at estimated81-93%- Corn at estimated 81-86%(USDA, 2011) Genetically Modified Plants
  5. 5. - Salmon DNAaltered so fishgrow tomaturity in halfthe time- TransgenicLivestock Genetically Modified Animals
  6. 6. - James Watson andFrancis Crick- Ultimately whatmade possible the-“Direct, intentionalalteration of thegenetic materials oforganisms bymoving genes fromone organism toanother” The Discovery of DNA-(Wohlers, 2010, p. 17)
  7. 7. Areas of Deliberation Regulative Policies Health Effect on Human Body Environmental/Economic Consequences
  8. 8. Regulative PoliciesHigh Uncertainty Low Uncertainty Southern Europe  North America South America  Scandinavia
  9. 9. RegulativePoliciesContinued…- Acceptance ofgeneticallymodified productsmay be highlydependent ondiffering politicalcultures- Market sharebattles betweencompanies
  10. 10. RegulativePoliciesContinued…- Not requiredto identifyvariousgeneticallymodifiedorganisms infood labels
  11. 11. Health Effects- Animal toxicitystudies withvarious GMO’shave shownpossiblenegative effectson certainorgans
  12. 12. Health Effects Continued… Does anyone in class have food allergies? Transgenic foods believed to have high food allergy potential  Salmon and corn transgenic example
  13. 13. Geneticallymodified crops canlead to certainenvironmentalbenefits- Usually lead to areduced use ofpesticides- Usually absorbfertilizer in moreproductive manner Environmental Effects
  14. 14. Geneticallymodified crops mayalso lead tobeneficial economiceffects- Increased cropyield and quality- Subsequentlyincreased profit Economic Effects
  15. 15. Conclusion GMO’s present both positive and negative aspects to society as a whole They are a topic of much deliberation and tension; very prevalent in some parts of the world and banned in others Ultimately, GMO’s are still a relatively premature technology and in the developmental process. Only time will reveal their ultimate effect on humans.
