  2. 2.  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.
  3. 3. 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.

Yet people continue eating products that contain chemicals or have been genetically modified on European ground.

  7. 7.  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.
  8. 8.  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
