Genetically modified foods

  1. 1. Genetically Modified Foods<br />Jaak Kalja<br />
  2. 2. Method <br />Insertion(lisamine) or deletion(kustutamine) of genes.<br />Artificial transfering between different organisms.<br />Gene gun.<br />
  3. 3. Growing Genetically Modified Crops<br />Between 1997 and 2005, the total surface area of land cultivated with GMOs had increased by a factor of 50, from 17,000 km2 (4.2 million acres) to 900,000 km2 (222 million acres).<br />Growing intrest in developing countries.<br />MONSANTO<br />
  4. 4. MONSANTO ( total monopoly in that area )<br />Bought ~ 90% of the agricultural seed companies. ( funded by the government )<br />Roundup<br />10% tax to the farmers<br />Total addiction – once you <br />go GMO, there’s no<br />turning back!<br />Farmers had no other <br />option. <br />
  5. 5. Economic and Political Effects<br />Geneticallyengineered crops claim they lower pesticide usage and have brought higher yields and profitability to many farmers<br />USAs export to Europe has decreased by 20%<br />Numerous bans to reduse GMO usage<br />
  6. 6. Helpful or Harmful?<br />Helpful<br />Harmful<br />Pest resistance.<br />Herbicide tolerance.<br />Disease resistance.<br />Cold tolerance.<br />Drought tolerance/salinity (soolsus) tolerance.<br />Helpful for malnutrition in developing countries.<br />Unintended harm to other organisms<br />Reduced effectiveness of pesticides<br />Gene transfer to non-target species<br />Unknown risk that the future might bring.<br />
  7. 7. Human Health Risks<br /><ul><li>Allergenicity
  8. 8. Unknown effects on human health
  9. 9. Toxicity
  10. 10. Specific components thought to have nutritional or toxic properties
  11. 11. Stability of the inserted gene
  12. 12. genetic modification(täiustus, muutus)</li></li></ul><li>The Most Toxic Foods <br /> Peaches <br />
  13. 13. Apples <br />
  14. 14. Sweet bell peppers <br />
  15. 15. Celery <br />

  22. 22. Strawberry <br />
  23. 23. Tomatoes <br />
  24. 24. Spinac<br />
  25. 25. And ofcourse basically every soybean and crop of corn is produced by genetical modification.<br />Soybean Corn <br />
  26. 26. GMOs in Estonia <br />Most of the GMOs are found in junk foods - ( burgers – meat ( soy etc ) )<br />Tests on processed foods ( 49 )<br />About 75% of soy; 5% corn<br />Estonia and all Europe is fighting against GMOs and so far Estonia don’t have very much of it <br />
