JKSSB Sub Inspector 2022 Q7 solved answer

Question

Which of the following is NOT a cause for the loss of biodiversity in general?

1. A. Co-extinction
2. B. Alien species invasions
3. C. Over exploitation
4. D. Reforestation

Answer

Correct option: D - Reforestation

Reforestation -- the process of replanting trees in areas where forests have been cleared -- is NOT a cause of biodiversity loss. It actually helps restore habitats and increases biodiversity. The major causes of biodiversity loss include: co-extinction (when a species dependent on another goes extinct), alien species invasions (which outcompete native species), and over-exploitation (hunting, fishing beyond sustainable limits).
