  1. GENETICALLY MODIFIED ORGANISMS

  2. Whatdoesitmean? • Itsgeneticmaterial (DNA or RNA) has beenchanged by geneticengineering • Cannotoccur in natureor in usualcrossbreeding • Micro-organisms, insect, plants, mammals

  3. Division • Haphazard mutagens and ionizingradiation wheat, canola,.. no regulations by law • Conscious transgenesis (Gene fromotherkindoforganismisused)

  4. Plants • To make them more resistantagainstpestsorweeds • To growfasterorbigger • To be more nutrtious • To createvaccinesorothermedications

  5. Animals • To createpets • To researchhumandiseases • To produce products intended for human therapeutic use (pharmaceutical products or tissue for implantation) • To produce industrial or consumer products

  6. GMOs & World • 90% of GM plants originate from the USA (50%), Argentina, Brazil or Canada

  7. GMOs & EU • AllofthecountriesbannedorsignificantlyreducedGMOs • EU authorized 31 modifications (cotton 6, corn 17, soya 3,..) • Ifsomeproductcontain GMO (more than 0,9%), it has to bestated on thepackaging

  8. Whyyes? • Use in medicine and research • Eliminatefamine • Betterresistance to weeds, pests and diseases • Foods with better texture, flavor and nutritional value

  9. SanJoaquinValley • California, USA • Importantagriculturalarea • Hugeincreaseofsoil salinity→ somecropscan’t growthere→ use genesof salt tolerant species (mangrove) to make thecropsgrowthereagain • Desert?!

  10. Why not? • Created just for a short period oftime→ wecan´treallysayifitisharmfulor not • May affect biodiversity • Food allergies • Antibioticresistance • Isithumaneatall?

  11. TheSchwarzeneggersofcows • Belgian Blue • Mutation in a protein whichstopsgrowingmuscles • Breedingformeat
