How does biotechnology contribute to sustainable agriculture?

• A. By increasing reliance on chemical pesticides
• B. By enhancing crop resilience to environmental stresses
• C. By promoting monoculture practices
• D. By encouraging the use of more water-intensive crops

Answer: (B)

Biotechnology contributes significantly to sustainable agriculture primarily through enhancing crop resilience to environmental stresses. This involves the use of genetic engineering, plant breeding techniques, and molecular markers to develop crop varieties that can withstand adverse conditions such as drought, salinity, and extreme temperatures. By improving the resilience of crops, biotechnology enables farmers to maintain yields and productivity in the face of climate change and decreasing arable land, thereby contributing to food security.

Additionally, resilient crops often require fewer inputs in terms of water, fertilizers, and pesticides, thereby reducing the environmental footprint of agriculture. This sustainable approach helps in maintaining biodiversity, improving soil health, and minimizing the ecological impact of farming practices. Thus, the focus on developing crops that can thrive under challenging environmental conditions aligns with the principles of sustainable agriculture, which seeks to balance productivity with environmental health.
