Since all stages of GMO conventional agriculture heavily rely on petroleum, how will this affect the price of food and environmental pollution in the long term? If we were to fully embrace GMO conventional wouldn't we be depending dangerously on a raw material that is getting more rare and increasingly expensive to acquire and process?

AExpert Answer

The facts do not support the idea that GM crops are more heavily reliant on petroleum than conventional or organic crops. One of the largest uses of petroleum in agriculture is for running machinery across fields to mechanically control weeds through tillage operations. Prior to the introduction of GM herbicide-tolerant crops, farmers were already adopting reduced tillage practices, which were made possible with the availability of selective postemergent herbicides that could be used on growing weeds without harming the crop. Since the introduction of GM crops, many studies have shown that the adoption of GM herbicide-tolerant crops has contributed to the increased adoption of reduced tillage systems.1, 2, 3, 4, 5, 6, 7 By contrast, organic growers are heavily reliant on tillage to control weeds, as the use of synthetic herbicides is prohibited under the USDA organic standard. As a result, organic growers not only use more fuel than growers of conventional and GM crops but cause increased erosion and decreased water retention of soils. Further, the adoption of GM insect-resistant crops has reduced the use of insecticides,8 which reduces the number of passes farmers make to apply insecticides—another major fuel savings.
