text: In 2000, the American journal Science published an article in which the authors said they had evaluated the ecological risks and benefits of genetically engineered plants by reviewing the scientific literature. En route to concluding that they could draw no conclusions, the authors neglected the proven benefits of GM organisms, including enhanced yields, nutritional enhancements, less use of chemical pesticides, and more no-till farming, which reduces soil erosion and chemical runoff and puts less carbon dioxide into the environment. At the same time, no detrimental effects of GM plants had, or have, been described.
