  1. Overexploitation occurs when natural resources are used excessively, often due to high commercial value, without considering the species' population dynamics, reproductive cycles, or size.
  2. The primary driver of overexploitation is always the direct consumption of resources by local populations for subsistence.
  3. Overexploitation issues are limited to plant and animal species and do not affect mineral or water resources.
  4. Sustainable resource management practices inherently lead to overexploitation because they restrict economic growth.
