Species can be difficult to define, but most biologists still feel comfortable with the concept and are able to identify and count eukaryotic species in most contexts. Biologists have also identified alternate measures of biodiversity, some of which are important for planning how to preserve biodiversity.

Five mass extinctions have occurred in geological history, and extinction rates were particular high during these events. Earth is currently experiencing a sixth mass extinction, which is driven by human activities. When mass extinctions are not occurring, extinction still occurs at a low rate, the background extinction rate. The local elimination of a species (extirpation) is also of conservation concern.
