Question
The number of animals in the wild is steadily declining. What might be the primary cause of this extinction?
- Predation
- Forest clearing
- Habitat degradation
- Hunting
Hint:
The number of animals in the wild is steadily declining. This is because of habitat degradation.
The correct answer is: Habitat degradation
- Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly.
- Geological processes, climate change, the introduction of invasive species, ecosystem nutrient depletion, and water and noise pollution are some examples. Loss of habitat can be preceded by initial habitat fragmentation.
