A Union of Concerned Scientists study shows that despite 20 years of research and 13 years of commercialization, genetic engineering has failed to significantly increase U.S. crop yields.

Biotechnology, bioengineering, and genetic engineering describe recombinant DNA technology, which allows scientists to cross species barriers. For example: inserting bacterial DNA into a plant to deliver traits such as pest or herbicide resistance.
GMO: Genetically modified organism
GE: Genetically engineered
RR: Roundup Ready
