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.

Traditionally, ecologists have measured biodiversity by taking into account both the number of species and the number of individuals of each species. However, biologists are using different measures of biodiversity, including genetic diversity, to help focus efforts to preserve the biologically and technologically important elements of biodiversity.

The main aim of conservation biology is to ensure the long-term preservation of biodiversity.

Measuring biodiversity on a large scale involves measuring ecosystem diversity (the number of different ecosystems on Earth), Species diversity (the number of different species in a particular area and their relative abundance), and genetic diversity (a measure of the variability among ind
