Read the passage below carefully and answer the question that follows.
In recent years, smallholder farming communities in eastern Nigeria have actively revived traditional seed-saving practices to safeguard native cassava varieties. While commercial agricultural vendors promote high-yielding hybrid cassava stems that require expensive chemical fertilizers, indigenous tubers possess natural resilience against regional pests and unpredictable rainfall patterns. Local agricultural cooperatives have established community seed banks, allowing farmers to exchange climate-resilient strains without incurring annual debt from commercial suppliers. Consequently, these grassroots seed-saving networks serve as the primary mechanism for preserving regional agro-biodiversity and securing household food independence. Although critics point out that traditional varieties produce lower immediate crop yields than lab-engineered hybrids, community leaders emphasize that long-term ecological sustainability and financial autonomy far outweigh short-term volume gains.
Which of the following best expresses the main idea of the passage?
