Nevertheless, human actions have caused huge losses in biodiversity, includingthe disruption of ecosystem processes, habitat destruction, species extinction and the erodingof genetic diversity within species.

In order to understand and conserve biodiversity we need to measure it effectively, withspecies richness being the most frequently used measure of biodiversity. At the momentaround 1.75 million species have been identified and estimates for the total number vary from3 to 100 million.
