How Roads End Languages

The geography that once preserved diversity now speeds its loss. When a new road reaches an isolated valley, it links a small community to the national language used for school, work, and money. Parents still speak the old tongue, but their children often grow up choosing the one that pays.

Where do these losses cluster? Mostly in tropical forests, remote islands, and high mountains — the very places geography protected longest. Globalization reaches them last, but once it arrives it moves quickly, and a language with only a few elderly speakers can fade within a single lifetime.
