This category examines the causes of biodiversity loss, particularly habitat loss and overexploitation, and their effects on ecosystems and species survival.
Conversion of forests into agricultural land and human settlements is the major cause of habitat loss and fragmentation, the leading cause of biodiversity loss.

Biodiversity hotspots are regions rich in endemic species that are under constant threat from habitat loss and therefore require priority conservation.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Loss of Biodiversity - Causes - Habitat Loss Overexploitation
Deforestation causes habitat loss and fragmentation, leading to a decline in biodiversity.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Loss of Biodiversity - Causes - Habitat Loss Overexploitation
Habitat loss and fragmentation are the most important causes of biodiversity loss because they reduce and isolate natural habitats.

The present extinction rate is estimated to be 100–1000 times higher than the natural extinction rate because of human activities.

The four major causes of biodiversity loss are habitat loss and fragmentation, overexploitation, alien species invasions, and co-extinctions.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Loss of Biodiversity - Causes - Habitat Loss Overexploitation
Human activities such as habitat loss and fragmentation, overexploitation, alien species invasions, and co-extinctions have greatly accelerated extinction rates.

Large-scale deforestation of the Amazon rainforest has caused extensive habitat loss and biodiversity decline.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Loss of Biodiversity - Causes - Habitat Loss Overexploitation
Human activities such as habitat loss and fragmentation, overexploitation, alien species invasions, and co-extinctions have greatly accelerated species extinction.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Loss of Biodiversity - Causes - Habitat Loss Overexploitation
Habitat loss and fragmentation are the most important causes of biodiversity loss because they reduce available habitat and isolate populations.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Loss of Biodiversity - Causes - Habitat Loss Overexploitation
Speciation increases biodiversity. The major causes of biodiversity loss are habitat loss and fragmentation, overexploitation, alien species invasions, and co-extinctions.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Loss of Biodiversity - Causes - Habitat Loss Overexploitation
Species with small populations are more vulnerable because they are more susceptible to habitat loss, environmental changes, and genetic problems.
