Acreage of GMO Varieties

Classical Plant Breeding : Genetic modification following introduction of large amounts of undefined DNA from a genetically similar source. Plant Biotechnology : Genetic modification of a plant cell by introduction of defined DNA(s) from a genetically different source.

Biotechnology : Bio = Biology Technology = Application “The application of Biology” (for the benefit of humans) Bio = Biology Technology = Application “The application of Biology” (for the benefit of humans)

Public Support Varies for Different Applications of Biotechnology (Includes ALL Countries – N = 35,000) Source: Thomas Hoban, North Carolina State University
15
The Benefits of Using Biotechnology are Greater than the Risks (35,000 Consumers from 35 Countries)
16
The Benefits of Using Biotechnology are Greater than the Risks (European Consumers)

Willing to Buy GM Food if More Nutritious (Net = Continue – Not Continue)

“ Can you think of any information not currently included on food labels that you would like to see?”
19
Perceptions of safety improved when US consumers learn that biotech foods have been in the stores. Do you think genetically modified foods are basically safe, basically unsafe, or don’t you have an opinion on this? Now, as you know, more than half of products in the grocery store are produced using some form of biotechnology or genetic modification. Knowing this, do you think genetically modified foods are basically safe, basically unsafe, or don’t you have an opinion on this? January 2001 Source: Pew Initiative on Food and Biotechnology
