Wildlife is continuously decreasing. What is the main reason of this ?
- Cutting down of forest
- Predation
- Hunting
- Destruction of habitat
Answer
(4) Destruction of habitat
Solution
As per NCERT, the causes of biodiversity loss are the 'Evil Quartet': habitat loss and fragmentation, over-exploitation, alien species invasions and co-extinctions.
⇒ Habitat loss and fragmentation is the most important cause driving animals and plants to extinction.
∵ Cutting down of forests is only one way in which habitats are destroyed; hunting and predation affect fewer species.
∴ The main reason for the decrease of wildlife is destruction of habitat.
