Genetically Engineered Crops
You may want to read at least the free summary of the recent National Academy of Science report on The Impact of Genetically Engineered Crops on Farm Sustainability in the United States.
According to the summary:
“Corn, cotton, and soybean that have been engineered to resist insect pests and herbicides are now planted on almost half of all U.S. cropland. An analysis of the U.S. experience with genetically engineered crops shows that they offer substantial net environmental and economic benefits compared to conventional crops; however, these benefits have not been universal, some may decline over time, and potential benefits and risks may become more numerous as the technology is applied to more crops. Understanding the impacts of genetically engineered crops is vital to ensuring that crop-management practices and future research and development efforts realize the full potential of genetic engineering for commercial as well as public goods purposes, while maintaining the environmental, economic, and social sustainability of U.S. farms.”
