Are GM crops classified as sustainable agriculture considering the thought of a positive feedback loop with an increased demand of the food supply?

AExpert Answer

I believe GM crops to be the most sustainable form of food production. One of the biggest challenges for farmers is the control of weeds. Weeds reduce the yield of the crop in the fields. GM crops provide such strong weed control that farmers have been able to remove tillage as a form of weed control in many instances. Prior to GM crops, most farmers would produce a crop in the same field for two or three years, then the weeds would be so abundant that the farmer would till the field regularly for an entire summer and not grow a crop that year in an effort to get better control of the weeds as the chemical options were limited in the 1970s and 1980s. With GM crops, farmers get very effective weed control, removing the need to summer fallow a field. This reduces soil erosion and increased moisture conservation, as well as reduces the greenhouse gas emissions from farming as the farmer makes fewer passes over his field presently. With strong adoption of zero-tillage farming, the sustainability of agriculture has increased substantially from GM crops.

 

I might suggest that the continued growth in adoption and number of acres planted to GM crops (using ISAAA data) would be evidence of positive feedback, given that more farmers are adopting GM crops and growing them on more acres.

First, the question is wrongly framed; it’s not true that there’s less “usage” of GMOs in developing countries. In a 2016 report, the International Service for the Acquisition of Agri-biotech Applications (ISAAA) reported that “of the top five countries growing 91 percent of biotech crops, three are developing countries (Brazil, Argentina, and India).” The other two were the U.S. and Canada. Although the U.S. led biotech crop planting in 2016...

Thank you for your questions, we would like to address these individually.   Why are GMOs created if scientists are not aware if it is really harmful? and Are GMOs really safe if you’re mixing to different DNA strands? yes GMOs are safe. In fact, according to this response, “the overwhelming consensus of scientific experts and major scientific authorities around the world, including the World Health Organization, Food and Agriculture Organization of the United Nations, and...

What we know from decades of scientific safety studies and research is that GM foods are safe for humans to eat. In fact, according to this response, “the overwhelming consensus of scientific experts and major scientific authorities around the world, including the World Health Organization, United Nations Food and Agriculture Organization and the American Medical Association have ruled that GMOs are safe.”   “In the spring of 2016, The National Academies of Science,...
