What is the main anthropogenic cause of biodiversity loss?

Correct answer: Habitat fragmentation and destruction

Correct answer: A, habitat fragmentation and destruction. Human activities convert forests, wetlands, grasslands and other natural areas into farms, roads, cities, mines and industrial sites. When a habitat is destroyed, organisms lose food, shelter, breeding sites and routes for movement. When it is fragmented, one continuous habitat becomes small isolated patches; populations may then become smaller and less connected, making survival more difficult. B is generally a conservation measure because planting or restoring suitable vegetation can improve habitat, although poorly planned planting is not automatically beneficial. C is intended to reduce a threat, not cause biodiversity loss. D protects habitats and species, so it is also a conservation measure. Memory cue: habitat loss is the first major threat—without a suitable home, species cannot persist.
