The idea sounds audacious: catalog all life on Earth within 25 years, a human generation. The All-Species Inventory hopes to do just that, with private funds and the help of a worldwide network of scientists and nature lovers. "It is a dream, but a neat one," says A.

He is one of 40 scientific advisers to the All-Species effort

It's a strange and fascinating sight, here under the Santa Catalina Mountains near dry little Oracle, Ariz., about 30 miles north of Tucson. Except for the walls and ceiling of glass triangles that enclose this million-gallon simulation of a Caribbean-type sea, the only obvious, unnatural object is a vacuum pump that provides a tidal pulse at the 25-foot deep end. Near the shallo
