It is predicted that within a century more than half of the worlds languages will become extinct, but as languages are lost, new ones emerge naturally or are constructed. In this program, Noam Chomsky; Esperantist Thomas Eccard; endangered languages researcher Peter Ladefoged, and others provide insights into the language life cycle. Topics include constructed languages such as Esperanto, language endangerment and preservation, and the role of globalization in language obsolescence. The experts also discuss current language trends and offer their opinions on which languages may emerge as front-runners in the future.
