Two global drivers of deforestation are agricultural expansion and timber demand. Which statement accurately reflects their effect?

• A. They drive forest loss and fragmentation
• B. They consistently increase forest regeneration
• C. They primarily improve soil quality
• D. They reduce forest area and fragmentation

Answer: (D)

The key idea is that these drivers cause loss of forest cover and break up large forests into smaller, isolated patches. When land is cleared for farming or pastures and trees are removed for timber, vast areas of forest are converted to other land uses, reducing total forest area. At the same time, the remaining forest is often cut, logged, or separated by roads and plantations, creating fragmentation. This fragmentation disrupts habitats, reduces connectivity, and can hurt biodiversity, edge ecosystems, and ecosystem services. They do not reliably boost regeneration, nor do they primarily improve soil quality, and they tend to increase fragmentation rather than reduce it. So the statement that best reflects their effect is that these drivers drive forest loss and fragmentation.
