How does the loss of biodiversity impact the environment and society?

• A. Increase in pest populations
• B. Decrease of food supply
• C. Improvement of soil quality
• D. Greater ecosystem resilience

Answer: (B)

The loss of biodiversity has significant implications for both the environment and society. When biodiversity decreases, the variety of life—including different species of plants, animals, and microorganisms—diminishes, which can lead to a decline in ecosystem services that are critical for food production. These services include pollination, soil fertility, and pest control, all of which are reliant on a diverse range of organisms. A decrease in biodiversity can disrupt these natural processes, resulting in reduced agricultural yields and a decline in the availability of food resources. Since diverse ecosystems are better equipped to handle pests, diseases, and environmental changes, the loss of species can lead to increased vulnerability in food systems. Consequently, a limited genetic variety in crops can result in food supplies that are less resilient to disease and climate fluctuations, leading to potential shortages and increased food insecurity. The other options do not accurately reflect the consequences of biodiversity loss. For instance, increased pest populations can occur, but this is more a consequence of lowering biodiversity rather than a direct impact on the environment and society. Similarly, the idea of improved soil quality contradicts the understanding that diverse organisms contribute to maintaining soil health. Greater ecosystem resilience is associated with higher biodiversity, not its loss. Therefore, the primary concern with biodiversity loss is
