摘要：What has long been suspected is true: genetically modified (GM) crops do have real benefits for the environment and for the economic well-being of farmers. A meta-analysis of peer-reviewed journal articles and other literature not published in journals reveals that the adoption of GM crops reduces pesticide input and increases crop yields and farmers’ income. The results confirm earlier and smaller studies and therefore are not unexpected. But they are particularly welcome for significantly informing the public debate on GM crops.
