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.

This is called projecting the population into the future and is a key step in population analysis for understanding the prospects of a population to increase, decrease, or even go extinct.

The current diversity of species is a product of the processes of extinction and speciation throughout the previous 3.8 billion year history of life. There might be 40 million species alive today, but between 5 and 50 billion species have lived at some time during the history of the Earth.

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