Genetically modified foods are foods derived from genetically modified organisms. Genetically modified organisms have had specific changes introduced into their DNA by genetic engineering techniques, that are more precise than mutagenesis where an organism is exposed to radiation or chemicals to create a non-specific but stable change.
GMO’s are a serious threat to biodiversity and areirreversible and unpredictable effects on ecosystems.Genetically modified foods involve aincreased use of toxics, geneticpollution and soil, loss ofbiodiversity, development ofresistance in insects and vegetationadventitia ("Weeds") and unwantedeffects on other organisms.Present a risk to health andagriculture.
ADVANTAGES OF GENETICALLY More capable of thriving inMODIFIED FOODS regions with poor soil or adverse climates. GM crops are more More environment friendly as productive and have a larger they require less herbicides and yield. pesticides. Foods are more resistant and Offer more nutritional value stay ripe for longer so they can and better flavor. be shipped long distances or kept on shop shelves for longer A possibility that they could periods. eliminate allergy-causing properties in some foods. As more GM crops can be grown on relatively small parcels of Inbuilt resistance to pests, land, GM crops are an answer to weeds and disease. feeding growing world populations.
The five applications are approved GMO potato cultivation of cash crops, the use of the potato starch as feed, and the marketing of three types of GM maize may not yet be gro It is alarming to note that while these large multinationals are enriched concentrating agricultural production, millions of people lose the historical legacy of its natural environment and see their livelihoods disappear. Yet people continue eating products that contain chemicals or have been genetically modified on European ground.
Resistance to droughts and extreme temperatures Increases in fixation of nitrate geno Resistance an acids grounds and /or saline grounds Herbicide resistance (allowing kill weeds without affecting crop) improvements · Nutritional quality modifications for early harvests more improved postharvest handling ·
Since April 2004, there is a new European law that requires labeling of products derived from GM crops for the presence of DNA or protein "transgenic". Thus, any food containing GMOs or derivatives must declare on the label.
Catalonia is the second European country where more GMOs are grown in Europe, for example corn, with 26,000 hectares. The Catalan government ignores all studies recommend ban GMOs. This view is also shared from Green -peace. In fact, from the NGO says it is a shame that the government in Catalonia itself progressive. In Spain, the CIS barometer of September 2006 revealed that the OMG were the main concern of the Spanish in relation to food
