"If your corn has a herbicide-tolerant gene, it means you can spray your herbicides and kill the weeds; you won't kill your corn because it's producing a gene that makes it tolerant of the herbicide"

This quote by Jeremy Rifkin is referring to the use of genetically modified organisms (GMOs) in farming. If a crop, such as corn, has actually been genetically modified to be tolerant to a specific herbicide, then it can be sprayed with that herbicide without killing the crop. This is helpful for farmers because it allows them to control weeds without harming their crops. This technology can likewise be used to produce crops that are resistant to certain bugs or illness, which can assist farmers increase their yields. Overall, this quote is highlighting the prospective benefits of utilizing GMOs in agriculture.
