Biodiversity and Extinction

This is the disappearance of a particular population from a given area, but not the entire species globally.

• extinction

• extirpation

• evacuation

• evaluation

This is the extinction of a species one by one, not a sudden loss of many species

• background extinction

• mass extinction

• fragmentation

• biotic potential

This classification of risk means that the species is at serious risk of extinction.

• threatened

• vulnerable

• endangered

• extinct

The status of a "threatened species" means:

• they are almost extinct

• they are likely to become endangered

• they are extinct

• their numbers are increasing

How is the current decline in biodiversity different from the previous mass extinctions that Earth has experienced?
