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.

No! However, poor nutrition coupled with highly processed foods and a lack of education regarding healthy eating is bad for our kids. As a mother and farmer, I believe the best way to keep my family safe and healthy is to make sure they eat a balanced diet and make good food choices daily. Fresh, healthy ingredients and minimally processed foods that are low in sugar, salt, calories and cholesterol provide kids with the best opportunity for a healthy diet. Agricultural biotechnology...

GMO crops are not "banned" in any countries around the world in the normal sense of that word. Usually when something is banned for consumption, etc., it is because some problem emerged that needed a response. The history of regulation for biotech crops is quite different in that there were regulatory approval processes developed long before any such crops were commercialized. The goal was to try to anticipate any potential health or environmental issues and to make...

These are definitely questions that many people are asking and researching to come up with answers.  In a day and age when a person can go to their smart phone to find a restaurant or search for directions, our society is definitely accustomed to finding answers quickly.   Unfortunately, complex issues take more time for the scientific community to research and develop answers. History is full of examples such as genetics, which started with the work of Gregor Mendel in 1856 and... Read More
