If farmers practiced sustainable agriculture and grew a variety of crops instead of one or two, they wouldn't have nearly as much need for GMO 'tools'. Our agricultural system encourages non-sustainable practices that practically require GMO seeds, pesticides, herbicides, and many others in order to continue to function. The companies that make these products want to ensure this continues.
GMO on it's own is fine, to me. But we need to stop looking at it as the solution to the problem we've created, and focus on fixing the root causes of big agriculture. These 'challenges' that are being addressed are often man-made.
