Genetically modified crops, also known as genetically engineered crops, are plants that have had their DNA altered or modified in order to enhance desired traits such as increased resistance to pests or herbicides, improved nutritional content, or better yield potential. This technology allows scientists to introduce specific genes from one organism into another to create crops with specific characteristics. Some of the most common genetically modified crops include corn, soybeans, cotton, and canola. The use of genetically modified crops has been a source of controversy, with concerns raised about potential environmental impacts, food safety risks, and the potential for negative effects on biodiversity. Proponents argue that genetically modified crops can help address issues such as food security, crop yields, and sustainable agriculture practices.
