Animals get extinct mainly due to

  1. Predation

  2. Habitat destruction

  3. Afforestation

  4. Pollution
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Habitat destruction is the process in which natural habitat is rendered functionally unable to support the species present. In this process, the organisms that previously used the site are displaced or destroyed, reducing biodiversity. Habitat destruction by human activity is mainly for the purpose of harvesting natural resources for industry production and urbanization. Clearing habitats for agriculture is the principal cause of habitat destruction. Other important causes of habitat destruction include mining, logging, trawling and urban sprawl. Habitat destruction is currently ranked as the primary cause of species extinction worldwide.

Therefore, the correct answer is option B.
