सामान्य प्रश्न
61. What are Genetically Modified (GM) products, and what are the key benefits and concerns associated with them, especially from an exam perspective?
Genetically Modified (GM) products are plants or animals whose genetic material has been altered using genetic engineering techniques. Key benefits include increased yields, reduced pesticide use, and improved nutritional value. Concerns revolve around potential environmental risks like herbicide-resistant weeds and impacts on biodiversity, as well as potential health effects. For the UPSC exam, understanding both sides of this debate is crucial.
परीक्षा युक्ति
Remember to balance the benefits and risks when answering questions about GM products in the exam. Cite examples where possible.
2. How do GM crops work in practice to achieve increased yields and reduced pesticide use?
GM crops are engineered to express specific traits. For increased yields, genes can be introduced to enhance photosynthesis or nutrient uptake. To reduce pesticide use, crops can be modified to produce their own insecticides, such as Bt toxin, which is toxic to certain pests. This reduces the need for external pesticide applications.
