Which of the following factor is the most important factor for the loss of biodiversity?

The destruction of natural habitat is widely recognized as the primary and most important driver of biodiversity loss. When ecosystems like forests, wetlands, and coral reefs are cleared or degraded for agriculture, infrastructure, and urbanization, species lose the essential resources required for survival, such as food, shelter, and breeding grounds.

• Habitat Fragmentation: This process breaks large habitats into smaller, isolated patches, which is particularly detrimental to large mammals and migratory species.
• Comparison: While factors like overexploitation, invasive species, and climate change (often grouped as the 'Evil Quartet') are significant, habitat loss remains the leading cause of extinction.
• Other Options: Control of predators, pest control, and genetic assimilation are specific ecological processes or human interventions that may affect certain populations but do not match the global scale of impact caused by habitat destruction.
