GENETICALLY MODIFIED
ORGANISMS
What does it mean? Its genetic material (DNA or
RNA) has been changed by genetic engineering
Cannot occur in nature or in usual crossbreeding
Micro-organisms, insect, plants, mammals
Division Haphazard
mutagens and ionizing radiation
wheat, canola,..no regulations by law
Conscioustransgenesis (Gene from other
kind of organism is used)
Plants To make them more resistant
against pests or weeds To grow faster or bigger To be more nutrtious To create vaccines or other
medications
Animals To create pets To research human diseases To produce products intended
for human therapeutic use (pharmaceutical products or tissue for implantation)
To produce industrial or consumer products
GMOs & World 90% of GM plants originate from
the USA (50%), Argentina, Brazil or Canada
GMOs & EU All of the countries banned or
significantly reduced GMOs EU authorized 31 modifications
(cotton 6, corn 17, soya 3,..) If some product contain GMO
(more than 0,9%), it has to be stated on the packaging
Why yes? Use in medicine and research Eliminate famine Better resistance to weeds,
pests and diseases Foods with better texture, flavor
and nutritional value
San Joaquin Valley California, USA Important agricultural area Huge increase of soil salinity→
some crops can’t grow there→ use genes of salt tolerant species (mangrove) to make the crops grow there again
Desert?!
Why not? Created just for a short period of
time→ we can´t really say if it is harmful or not
May affect biodiversity Food allergies Antibiotic resistance Is it humane at all?
The Schwarzeneggers of cows
Belgian Blue Mutation in a protein which
stops growing muscles Breeding for meat
Thank you for your attention
