Destruction of habitat which leads to deprivation of shelter and food for animals. Pollution which is a subtle form of habitat destruction which may reduce and eliminate the population of sensitive species.

Introduction of exotic species- new species may kill or eat native species to the point of extinction or may alter the habitat that many natives are no longer able to persist. Disturbance and degradation of habitat-natural disturbances and degradation are caused by spontaneous jungle fire, pest infection deforestation, by an insect, locust attack etcetera. Man-made disturbances and degradation and more severe.
