Vanishing Species
Counting our Natural Blessings A study by Canada’s Dalhousie Universi-
ty postulates that as many as 86 percent of Earth’s species are still unknown, and millions of organisms will remain undiscovered as extinctions acceler- ate worldwide at 10 to 100 times their natural rate.
ate. If, as the study’s co-author Boris
Worm suggests, our planet is home to 8.7 million species, it means scientists have cataloged fewer than 15 percent of species now alive. Many unknown organisms will wink out of existence before they can even be recorded.
Although the catalog of mammals and birds may be nearly complete, invento- ries of other classes of life are far behind. Only 7 percent of the predicted number of fungi and fewer than 10 percent of all ocean life forms have been identified. Categorizing a new organism is more complicated than discovering one. “It’s a long process,” Worm explains. “Most scientists will describe dozens of species in their lifetime, if they’re really lucky. What’s been discovered so far are those things that are easy to find, that are conspicuous, that are relatively large. There is an age of discovery ahead of us when we could find out so much more of what lives with us on this planet.”

Big Book Encyclopedia of Life Update
The second edition of the Smithsonian Institution’s free, online collaborative Ency- clopedia of Life (EOL) is now easier to use. It also has been vastly expanded, offer- ing information on more than one-third of all known species on Earth, including hundreds of thousands of images and videos. With the updated format, users can easily find species of interest; create per- sonal collections of photos and information; find or upload pictures, videos and sounds; and share comments, questions and expertise with users worldwide that share similar interests.
EOL.org seeks to become a microscope in
reverse, helping users to discern large-scale patterns. By aggregating for analysis information on Earth’s estimated 1.9 million known species, scientists say EOL could, for example, help map vec- tors of human disease; reveal mysteries behind longevity; suggest substitute plant pollinators for a swelling list of places where honeybees no longer provide the function; and foster strategies to slow the spread of invasive species.
