This estimate, which results from analysis based on the latest proven techniques in taxonomy, can significantly strengthen the figures above, which varied from 3 to 100 million species. 'The question of how many living species exist on Earth has intrigued scientists for centuries and this response, coupled with other research on the distribution and abundance of species, is particularly important because human activities and impact speed the extinction rate ', said Camilo Mora, University of Hawaii and Dalhousie, Halifax (Canada), and lead author of the study.

According to the researcher, 'number of species could disappear before we even knew about it, their unique function in the ecosystem and their potential contribution to improve the well-being of humans'. The recent update of 'Red List' prepared by IUCN (International Union for Conservation of Nature) reported 59 508 monitored species, including 19,625 are threatened with extinction, is Boris Worn, the Dalhousie University, co-author of the communication.
