Extinctions happen when a species dies out from cataclysmic events, evolutionary problems, or human interference. Extinction happens when environmental factors or evolutionary problems cause a species to die out. The disappearance of species from Earth is ongoing, and rates have varied over time.

Extinction is a natural process that may be caused by natural selection, shortage of food or natural calamities. Man’s action on nature has also caused entire animal species to disappear over the years.

regional extinction. When the members of a species are extinct in a localized area, but there are still members of the species alive elsewhere in the world. functional extinction. When the number of individuals in a species is so low, they no longer play their functional roles in the ecosystem.

Extinction, in biology, the dying out or extermination of a species.

Human extinction is the hypothetical end of the human species due to either natural causes such as an asteroid impact or large-scale volcanism, or anthropogenic (human) causes, also known as omnicide. The likelihood of human extinction through our own activities, however, is a current area of research and debate.

Half of Earth’s species could go extinct by 2050 unless humanity addresses man-made climate change, according to biologists. There have been five mass extinctions in the history of planet Earth.
