Scientists want to know how many species we share the planet with—especially since we're killing them off at least 100 times faster than at any period in recent geologic history
The latest census effort guesstimates roughly 8.7 million species on Earth and notes that we know only 1.2 million of them. It’s published in the journal Public Library of Science Biology.
After all, there can be thousands of different microbes in a single spoonful of earth or sea. Pity the poor nematode that may vanish from the record of life before we even know it.
