A mass extinction can be define as death of large population of a species due to natural hazard or due human induced impacts over the environment.
Following are the examples of human created mass extinction:
1. It results from the disappearance of entire species in a short time.: Human induced impacts like nuclear explosion can lead to the disappearance of the entire species in short time.
3. It is caused by the growth of the human population.: With the advent of human population worldwide the demand for resources like habitat, water, food and other needs increased. This lead to the extinction of many flora and fauna species.
