What is mass extinction? To better comprehend the term mass extinction, it is paramount that the word extinction is also defined and understood. An organism is said to be extinct when no member of its species exists on earth. This is can be attributed to the fact that not all life is supported on earth. The other reason why a species may go extinct is simply that members of that species cannot survive given the existing conditions. There are terminologies that have been developed to better understand the concept of extinction, and thus that of mass extinction. These include locally extinct and globally extinct. The former means that members of a certain species are completely unavailable in particular local habitats where they initially would be found. The latter, on the other hand, implies that members of a certain species cannot be traced or found to be existing in any known habitat in the world. There are two types of extinction, namely, background and mass extinction. Background extinction refers to what can be termed as normal extinction. It is a measure of how naturally species go extinct either because not all forms of life can be sustained on planet earth or members of that species cannot survive. However, the background extinction definition simply touches on the extinction of single species as opposed to multiple species. .
