Drivers and impacts of biodiversity loss – UGC NET Question

Statements A, B, C and D are correct as they list key drivers of biodiversity loss and main strands of conservation responses. Habitat change, overuse and invasive species are major pressures, and protected areas, restoration and sustainable use are core strategies. E is wrong because biodiversity loss undermines ecosystem services and human well-being, and F is wrong since climate change is a significant driver shifting species distributions and extinction risks. Thus, the correct combination is A, B, C and D only.

Option A:
Option A is incorrect because it omits D, thereby ignoring the variety of conservation strategies employed to tackle biodiversity loss. Without D, the answer mentions only pressures and not the policy and management responses.

Option B:
Option B is incorrect since it includes E, which falsely claims that biodiversity loss has no implications for ecosystem services. Accepting E contradicts the central theme that biodiversity underpins services such as pollination, water regulation and cultural values.

Option C:
Option C is incorrect as it includes F, which denies the link between climate change and biodiversity loss, while also excluding A. Dropping habitat destruction, one of the most important drivers, makes the combination incomplete and conceptually weak.

Option D:
Option D is correct as it contains all four accurate statements on drivers and responses while excluding E and F, which downplay consequences and disconnect climate change from biodiversity loss. It matches the integrated understanding presented in the unit.
