GMOs (genetically modified organisms) have sucked up billions of research dollars and prolonged agriculture's dependence on chemical inputs, but they have yet to justify their role. A recent review of on-farm production levels of genetically modified crops showed less than marginal gains in actual yield. In fact, the review concluded that "no currently available transgenic varieties enhance the intrinsic yield of any crops."

If GMOs are developed to increase yields, then they have failed. If they are marketed to reduce costs for farmers, the price of GMO corn seed is now three times greater than it was just a few years ago. If these seeds are engineered to use less herbicides, many weeds are becoming Roundup-resistant, requiring a cocktail of herbicide applications in certain farming areas. And their safety is still in question.
