The only factor in the diversity of language, is the isolation of cultures. The less isolated cultures are, the less any individual could be bothered to speak a different language. As the world becomes more integrated, and less isolated, even major languages will begin to disappear. I see this happening with one of my favourite languages: Japanese. Colloquial Japanese is slowly replacing words with close English approximations (just as it took on German vocabulary in the early 20th century), dialects are at once becoming more widely understood, and more similar. You can no more preserve a language than you can preserve a human being.
