    Actually the fact is that this technology is being used to grow crops more efficiently using LESS insecticides, safer herbicides, fewer resources, and less water.

    In her recent paper entitled “Will Common Sense Prevail?” in the peer-reviewed journal Trends in Genetics, (www.ncbi.nlm.nih.gov/pubmed/23069214) Dr. Nina Fedoroff writes:

    “FACT: insect-resistant Bt crops have markedly reduced pesticide use. Approximately 443 million kg less pesticide (active ingredient) was ap-plied to fields between 1996 and 2010 because insect-resistant crops were being grown. Less pesticide means more beneficial insects and birds, and less pesticide contamination of water.

    FACT: herbicide-tolerant crops have made big strides in reducing topsoil loss and improving soil quality.No-till farming keeps the soil on the land and the organic matter and water in the soil. It also reduces CO2 emissions from tillage: in 2010 alone, this reduction was equivalent to taking 9 million cars off the road.(Global Impact of Biotech Crops: Environmental Effects, 1996-2008 www.agbioforum.org/v13n1/v13n1a06-brookes.pdf)”

    According to a report by the National Research Council in 2010 entitled “Impact of Genetically Engineered Crops on Farm Sustainability in the United States” Available for free online at www.nap.edu/catalog.php?record_id=12804#toc it was found that
    many U.S. farmers who grow genetically engineered (GE) crops are realizing substantial economic and environmental benefits — such as lower production costs, fewer pest problems, reduced use of pesticides, and better yields — compared with conventional crops. “Many American farmers are enjoying higher profits due to the widespread use of certain genetically engineered crops and are reducing environmental impacts on and off the farm,” said David Ervin, professor of environmental management and economics, Portland State University, Portland, Ore., and chair of the committee that wrote the report

    First introduced in 1996, genetically engineered crops now constitute more than 80 percent of soybeans, corn, and cotton grown in the United States. GE soybeans, corn, and cotton are designed to be resistant to the herbicide glyphosate, which has fewer adverse environmental effects compared with most other herbicides used to control weeds. In addition to glyphosate resistance, GE corn and cotton plants also are designed to produce a Bt protein that is deadly when ingested by susceptible insect pests but has no effect on humans and is one of the insecticides that is approved for organic production systems.

    ENVIRONMENTAL BENEFITS
    Improvements in water quality could prove to be the largest single benefit of GE crops, the report says. Insecticide use has declined since GE crops were introduced, and farmers who grow GE crops use fewer insecticides and herbicides that linger in soil and waterways. In addition, farmers who grow herbicide-resistant crops till less often to control weeds and are more likely to practice conservation tillage, which improves soil quality and water filtration and reduces erosion.
