This program travels the globe as it surveys a large portion of the worlds languages&́#x80;25 percent of which are spoken by a mere 0.1 percent of the Earths population. Moving from Africa to Oceania and up to Asia and then west to Europe and across the ocean to the Americas, the program assesses how many languages are spoken in each region, the characteristics they share, and misconceptions about them. Historical background on some of the key languages of the regions is included as well. The commentary of Salikoko Mufwene, coeditor of The Ecology of Language Evolution; Larry Hyman, of U.C. Berkeley; Hua Lin, of the University of Victoria; Harvard University's Jay Jasanoff and Lyle Campbell, of the University of Utah, are featured.
