उत्तर

Sr. No. Advantages Disadvantages
1. Genetically modified (GM) crops have shown significant increases in yield and productivity. There could potentially be a reduction in the genetic diversity of crops.
2. GM crops show resistance to pests and diseases, reducing the need for chemical pesticides. They could potentially harm non-target organisms such as beneficial insects.
3. GM crops can tolerate abiotic stresses such as drought and salinity. Altered gene expression in GM crops may lead to unforeseen negative effects.
4. GM crops like Golden Rice, enriched with Vitamin A, offer enhanced nutritional value. There are potential health risks, such as allergenicity or toxicity, in genetically modified food.
5. The use of GM crops reduces agrochemical usage, thus lowering environmental pollution. Farmers’ dependence on biotech companies for GM seeds raises socio-economic and ethical concerns.
