“We estimate that there are a total of around 13 million species (known and unknown) in the world,” says Thomas Lewinsohn, a renowned professor of ecology at the State University of Campinas (UNICAMP) in Sao Paulo state.

“Out of these, roughly 1.75 million species, including micro-organisms, plants, insects, bacteria and animals, have been described,” he told AFP in an interview.

And it would take 2000 years to describe them all.
