Which of the following is the most important cause of animals and plants being driven to extinction?

Explanation

Destruction of natural habitats causes the most serious threat to biodiversity. Over­ population, urbanization, and industrialization lead to the destruction or fragmentation of natural habitats to fulfill the requirement for additional land. Loss of habitat results in the annihilation of plants, and microorganisms, and the forcing out of animals which in alien lands die out after some time. Fragmentation of habitats results in the disruption of complex interactions amongst species, destruction of species in the cleared regions, annihilation of species restricted to deeper undisturbed parts of forests, and decreased biodiversity in the habitat fragments.
