Ten good reasons why GMOs are not compatible with organic agriculture

Despite fundamental differences in what they represent, there are occasional calls to allow the use of genetic engineering (which produces genetically modified organisms, known as GMOs) within the USDA National Organic Program. GMO varieties are currently most widespread in corn, soybean, canola and cotton crops, in dairy production, and in minor ingredients, such as dairy cultures, used in food processing, but new products are being introduced and commercialized.

Here are 10 essential points that I believe show why GMOs are incompatible with organic production:

1. Basic science. Humans have a complex digestive system, populated with flora, fauna, and enzymes that have evolved over millennia to recognize and break down foods found in nature to make nutrients available to feed the human body. GMO crops and foods are comprised of novel genetic constructs which have never before been part of the human diet and may not be recognized by the intestinal system as digestible food, leading to the possible relationship between genetic engineering and a dramatic increase in food allergies, obesity, diabetes, and other food-related diseases, which have all dramatically increased correlated to the introduction of GMO crops and foods.

2. Ecological impact. Organic agriculture is based on the fundamental principle of building and maintaining healthy soil, aquatic, and terrestrial ecosystems. Since the introduction of GMOs, there has been a dramatic decline in the populations of Monarch butterflies, black swallowtails, lacewings, and caddisflies, and there may be a relationship between genetic engineering and colony collapse in honeybees. GMO crops, including toxic Bt corn residues, have been shown to persist in soils and negatively impact soil ecosystems. Genetically modified rBST (recombinant bovine somatrotropin, injected to enhance a cow’s milk output) has documented negative impacts on the health and well being of dairy cattle, which is a direct contradiction to organic livestock requirements.

3. Control vs harmony. Organic agriculture is based on the establishment of a harmonious relationship with the agricultural ecosystem by farming in harmony with nature. Genetic engineering is based on the exact opposite -- an attempt to control nature at its most intimate level - the genetic code, creating organisms that have never previously existed in nature.

4. Unpredictable consequences. Organic ag is based on a precautionary approach - know the ecological and human health consequences, as best possible, before allowing the use of a practice or input in organic production. Since introduction, genetic modification of agricultural crops has been shown to have numerous unpredicted consequences, at the macro level, and at the genetic level. Altered genetic sequences have now been shown to be unstable, producing unpredicted and unknown outcomes.
