We’re Not Alone: 8,699,999 other species on Earth

jtotheizzoe:

8,700,000: Newest estimate of eukaryotic species on Earth (doesn’t count bacteria, etc.)

1,200,000: Number of species we have catalogued in the past 250 years

$48,500: Estimated cost of cataloguing a species, including paying those pesky scientists

1,200: The number of years it would take to catalogue the rest at this rate (and at a total cost of $364 billion)

I think we need a new system.

(Thanks to Jennifer Jacquet for doing that math for me at SciAm)
