the debate

Along with environmental activism, food awareness has recently come to prominence. Books such as The Omnivore's Dilemma by Michael Pollan and movies such as Food, Inc. call upon the public to take greater ownership over what we consume. One of the major issues in food awareness that sometimes slips under the radar is that of genetically modified foods. The main argument for creating and growing genetically modified crops is the great potential they have as solutions for such problems such as world hunger, nutrient deficiency, resource managment, and pesticide avoidance. Despite this high potential, it is important to be wary of progress and stress safety in any creation of a new entity. Among the opponents of genetic modification of crops, many of the arguments revolve around wariness of the risks of gmo's. Below, we've outlined some of the major arguments made against the safety of gmo's, and the rebuttals made by the GE community.


Health Risks There are many unknowns with regard to the risks we take when consuming genetically engineered plants. In plant engineering, constructs are inserted randomly into the genome, which creates the potential for unanticipated effects on plant metabolism. It is near impossible to predict the creation of new allergens or the side production on toxins in plants from the changes in plant metabolics. The risks that apply to genetically engineered plants also apply to plants cross-bred in the conventional manner. In traditional plant cross-breeding, whole chromosomes are transferred and may recombine in a random manner (talk about incorporation of genetic material from different kinds of plants).
herbicide/pesticide use
Genetic Pollution Genetically engineered plants have the potential to spread their genetic material to non-engineered strains and to native species, creating a threat to environmental security. It is difficult to track and recall if necessary genetic material that has already been released into the environment. Genetically engineered plants are ususally less viable in the wild, and horizontal transfer is unlikely (why???)
Effects on Ecosystems Butterflies + competition with native species (decrease in biodiversity Look closer at the studies
