6 causes of extinction of wildlife species

a) Alteration of habitat:

Destruction of the habitat of a particular wildlife species intentionally or unintentionally leads to extinction of species. The habitat may be destroyed by deforestation, drainage, overgrazing, expanding agriculture, urban and suburban development, highway construction, dam building, etc. As a result of destruction of its habitat, the species must either adapt to the changes, move elsewhere or many succumb to predation, starvation or disease and die.

b) Commercial sport and subsistence, hunting:

Nature has great diversity. It is created, over many millions of years, a large number of species of plants and animals. But it is man who is responsible for the extinction of plant and animal species
