What is a significant environmental benefit of agricultural biotechnology?

The choice highlighting the enhancement of crop efficiency and the sequestration of carbon is significant because agricultural biotechnology aims to develop crops that are better suited to resist pests, diseases, and environmental stresses. This improved resilience means that crops can thrive with fewer inputs, such as water, fertilizers, and pesticides, ultimately leading to more efficient resource use.

Furthermore, some biotechnological advances lead to the development of crops that possess traits to capture and hold carbon in the soil more effectively. By fostering plants that can sequester carbon, agricultural biotechnology contributes to reducing greenhouse gas concentrations in the atmosphere, which is crucial in combating climate change.

In contrast, the other options indicate practices that tend to have negative implications for the environment. Increasing greenhouse gas emissions, promoting excessive fertilizer use, and encouraging mono-crop farming practices all lead to detrimental ecological impacts, such as soil degradation, loss of biodiversity, and increased pollution. Therefore, the focus on enhancing crop efficiency and carbon sequestration represents a key environmental benefit of agricultural biotechnology.
