What is a potential risk associated with genetically modified (GM) crops?

• A. Promotion of sustainable farming practices
• B. Development of insect-resistant weed populations
• C. Increase in crop yield
• D. Improvement of soil health

Answer: (B)

The potential risk associated with genetically modified (GM) crops lies in the development of insect-resistant weed populations. This occurs when GM crops are engineered to be resistant to specific herbicides, which can lead to the overuse of these chemicals in agricultural practices. Over time, the continuous application of the same herbicides can exert selective pressure on weed populations, allowing those that have naturally occurring resistance to survive and reproduce. As a result, these resistant weeds can proliferate, making them more difficult to control, leading to increased herbicide use and potentially creating a cycle of dependency on new herbicides or more aggressive control measures. In contrast, promoting sustainable farming practices, increasing crop yield, and improving soil health are often benefits associated with GM crops. These aspects highlight the positive applications of genetic modifications, but they do not address the specific risks that emerge from such practices. The focus on the unintended consequences, such as the emergence of resistant weed populations, presents a more nuanced understanding of the challenges in GM agriculture.
