Final answer:
Biotechnology enhances crop yields on limited farmland through genetic engineering for disease and pest resistance, which also supports safe pest control and cost-effective production. The answer is option A.
Step-by-step explanation:
Biotechnology has begun to improve crop yields on shrinking amounts of farmable land. By engineering crops to be resistant to specific herbicides, diseases, and pests, biotechnology provides tools that make production more manageable and cost-effective.
Through the use of genetically engineered crops, farmers can cultivate crops that are resistant to specific plant diseases, insect pests, and environmental conditions such as drought. This leads to more efficient pest control, reduced production costs, and increased food production to meet growing demands.
Genetically engineered crops such as herbicide-tolerant soybeans and insect-resistant cotton also contribute to safer pest control and weed management practices, thereby safeguarding the environment and maintaining biodiversity while improving agricultural yields.
