What is the potential environmental benefit of agricultural biotechnology?

The option highlighting the reduction of pesticide use through pest-resistant crops is correct because it addresses a significant environmental benefit of agricultural biotechnology. Pest-resistant crops are genetically engineered to withstand specific pests, which reduces the need for chemical insecticides. This has a positive impact on the environment by decreasing chemical runoff into water bodies, minimizing harm to non-target organisms, and promoting biodiversity in agricultural ecosystems.

Importantly, the development of such crops can lead to more sustainable farming practices. By reducing the need for pesticides, farmers can not only lower their production costs but also contribute to improved soil health and reduced toxicity in the environment. This shift ultimately fosters more resilient agricultural systems and helps maintain ecosystem balance.

In contrast, the other options do not present environmental benefits. Increased reliance on chemical fertilizers contributes to nutrient runoff and soil degradation, while encouraging monoculture practices can diminish biodiversity and increase vulnerability to disease outbreaks. The increased use of genetically modified seeds, when not paired with sustainable practices, can contribute to issues like genetic erosion and dependence on specific seed varieties. Therefore, the reduction of pesticide use through pest-resistant crops stands out as a clear advantage in promoting environmental sustainability in agriculture.
