What is a significant disadvantage of GMOs?

• A. They provide less food yield.
• B. They increase herbicide use significantly.
• C. They improve the nutritional value of food.
• D. They have no environmental impact.

Answer: (B)

The assertion that GMOs may increase herbicide use significantly is a well-founded concern in the discussion around genetically modified organisms. Many GMO crops are engineered to be resistant to specific herbicides. While this can facilitate weed management for farmers, it can also lead to an increase in the quantity and frequency of herbicide applications. This increased herbicide use has potential downsides, including the evolution of herbicide-resistant weed populations, which can require even more aggressive chemical interventions. Additionally, the environmental and health impacts of higher herbicide usage have raised concerns among scientists and the public alike. Thus, this aspect highlights a critical disadvantage of GMOs, reflecting the complexity of agricultural biotechnology and its long-term effects on ecosystems and farming practices. In contrast, other options suggest benefits of GMOs or lack of impact, which do not align with the significant concerns raised about their use and environmental footprint.
