This program travels the globe as it surveys a large portion of the world's languages-25 percent of which are spoken by a mere 0.1 percent of the Earth's 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.
