According to a report released in April by the National Research Council, GE crops lower production costs, reduce pesticide use and improve yields. And GE crops enhance the environment because they reduce soil erosion and improve water quality, the report says. Of course, GE opponents would like to scream bloody murder that somehow the panel that performed this study is biased, self-serving and conflicted by special interests. But none of that will stick to the wall. They targeted crops such as corn, soybeans and cotton that had been genetically engineered to be glyphosate-tolerant or produce Bacillus thuringiensis (Bt) toxins that are lethal to the larvae of some insects. Overall, the report was an affirmation of the experience farmers have had with genetically engineered crops since they went commercial in 1996. The research drilled down on the effect that plant technology has had on farmers, and that impact has been dramatic. The study’s key conclusions:
• Farmers who have adopted GE crops have experienced lower costs of production and higher yields, including in some areas where insect populations were hard to treat without such crops.
• Increased worker safety and greater flexibility of farm management have resulted.
• “The adoption of herbicide-resistant crops complements conservation tillage practices, which in turn reduces the adverse effects of tillage on soil and water quality,” the scientists wrote.
• “Insecticide use has decreased with the adoption of insect-resistant crops,” they wrote, noting that insect resistance to the technology has been low.
• For the three major genetically engineered crops – corn, soybeans and cotton – cross-breeding into wild or weedy relatives hasn’t been a problem.
