Question

Among ‘The Evil Quartet’, which one is considered the most important cause driving extinction of species?

• A. Over exploitation for economic gain
• B. Alien species invasions
• C. Co-extinctions
• D. Habitat loss and fragmentation

Answer 1

Answer: (D)

Habitat loss and fragmentation

Answer 2

Habitat loss and fragmentation have significant impacts on biodiversity and are often cited as the primary driver of species extinction. This process disrupts ecosystems, reduces available habitat, and can lead to isolation of populations, making species more vulnerable to various threats. The other factors in the 'Evil Quartet' (over exploitation for economic gain, alien species invasions, and co-extinctions) also contribute to species decline, but habitat loss and fragmentation are often seen as the underlying driver.

Therefore, The correct option is (D): Habitat loss and fragmentation
