Never before has the planet s linguistic diversity shrunk at such a pace. At the moment, we are heading for about three or four languages dominating the world, says Mark Pagel, an evolutionary biologist at the University of Reading. It s a mass extinction, and whether we will ever rebound from the loss is difficult to know. Isolation breeds
