Scientists do a recount on bugs

Planet Earth could be home to millions fewer species than previously thought, new research has claimed.

Around 16 million fewer types of beetles and 30 million fewer types of terrestrial arthropods than calculated in the 1980s could actually exist. By developing a more accurate measurement of specie numbers, scientists at Griffith University in Australia hope to discover the impact humans are having on extinction levels. Their measurements are one of four new methods adopted for counting species since 2001.
