A study conducted by researchers from Purdue University reveals that a global ban on genetically modified (GM) crops would raise food prices and add the equivalent of nearly a billion tonnes of carbon dioxide to the atmosphere.

The researchers used a model to assess the economic and environmental value of GM crops, and found that replacing GM corn, soybeans, and cotton with conventionally bred varieties worldwide would cause a 0.27 to 2.2 percent increase in food costs, depending on the region, with poorer countries hit hardest. The study also reports that a ban on GM crops would also trigger the conversion of pastures and forests to cropland to compensate for lower productivity of conventional crops, which would release substantial amounts of stored carbon to the atmosphere.
