Urbanization, deforestation, and land conversion for agriculture significantly disrupt ecosystems, leading to species extinction and reduced genetic diversity.
Water pollution (A) and agricultural runoff (D) certainly harm ecosystems and threaten species, but they are often consequences of habitat destruction rather than the main cause. Hunting and fishing (B) can impact specific populations but do not account for the widespread loss of habitats affecting entire ecosystems.
