Biotechnology and Genetic Disruptions

From The Academics Review Criticism of 'Genetic Roulette'

 “It is certainly true that crop breeding changes DNA; in fact, that is the purpose of all breeding programs—to create differences in DNA.  Campaigners who are opposed to GM crops consistently point to the potential harmful effects of DNA inserts, and the potential presence of multiple fragments of new DNA in a transformed plant.  There are several problems with their assertions: 1) All plant chromosomes are repeatedly disrupted by many structural changes to DNA that have occurred in plants repeatedly over the course of recent history, and still occur today when plants are grown each season in the field; 2) All breeding technologies produce numerous changes and disruptions to the structure of plant chromosomes; 3) Conventional breeding techniques, accepted as safe by all, cause much more genetic disruption than those introduced by genetic engineering, and the resulting plants are not tested extensively for genetic change nor for safety attributes using the rigorous standards applied to genetically engineered plants.”
 “Indeed, the use of more precise technology and the greater regulatory scrutiny probably make them even safer than conventional plants and foods; and if there are unforeseen environmental effects – none have appeared as yet – these should be rapidly detected by our monitoring requirements. On the other hand, the benefits of these plants and products for human health and the environment become increasingly clear.” ( European Commission 2001)
