Soybean is a major crop used for animal feed and human food worldwide. Weeds compete with soybeans, reducing yields. Some soybean varieties have been genetically modified (GM) to be resistant to a specific broad-spectrum herbicide. Farmers can then spray the herbicide to kill weeds without harming the soybean plants.
Outline how the development of herbicide-resistant soybean crops can help meet global food demand. In your answer, also state one ethical or social concern associated with the use of such GM soybeans.
