Vedclass · Answer

(D) Biodiversity loss is primarily driven by human activities that negatively impact ecosystems. The four major causes,often referred to as the 'Evil Quartet',are:$1$. Habitat loss and fragmentation: This is the most significant cause,where natural habitats are destroyed or broken into smaller pieces.$2$. Over-exploitation: Humans over-harvest species for food,medicine,or trade,leading to population decline.$3$. Alien species invasion: The introduction of non-native species can outcompete or prey upon native species,causing their extinction.$4$. Co-extinction: When a species becomes extinct,the plant and animal species associated with it in an obligatory way also become extinct.Since all four factors listed $(i, ii, iii, iv)$ are recognized as primary causes of biodiversity loss,the correct option is $(D)$.
