C. Habitat destruction

Explanation:

Habitat destruction is one of the biggest threats to biodiversity-it is the number one reason species go extinct. Clear cutting forests to create fields, filling in wetlands to build houses, and creating dams that change river flow are all examples of habitat destruction.

Clearing habitats for agriculture, for example, is the principal cause of habitat destruction. Other important causes of habitat destruction include mining, logging, and urban sprawl. Habitat destruction is currently ranked as the primary cause of species extinction worldwide reducing biodiversity.
