While a common wisdom has it that fewer languages existing for communication would bring about the convenience in our daily life, I would argue that the disappearance of those linguistic data is not of insignificance.
One of the reasons why most languages should not be dismissed may lie to the fact that languages have recorded the things happened in the past for a particular ethic group. Those histories and stories vividly have reflected how our ancestors had struggled with their life against all the hardships and fierce surroundings, and how they sincerely adhered to the final humanities via some of the aforementioned languages. Without the ability of interpreting this linguist data, we may lose forever the experience and guidelines that could be injected from the former generations, and therefore make the same mistakes occurred once in the historical time when exploring a particular geographic place. Another source of why those languages ought not to vanish may due to the culture identity, or should I say the thought diversity, lying behind which people insist on in some specific ethic groups. Those thoughts, recorded mostly by multiple languages, though weakened gradually resulted from the invasion of the stronger civilizations, indeed are the perfect reference in which the whole society can strengthen its improvement by fixing the flaws at the meantime. The loss for words of some particular communities would somewhat discourage the possibilities of the further steps of the society itself.
Notwithstanding the huge convenience brought about when the “babel” time could re-emerge via letting down the barrier of misunderstandings derived from the various languages, this action also gestates more calamities than contributions. Livings in the social communities granted involve the pursuit of efficiency and convenience, but other elements and identities —diversity of lives among cultural groups, customs and traditions established in a particular geographic location that are with human wisdom and sophistications, civilizations fostered by people from harnessing the natural surroundings to fit with their lives, etc.—are also valued seriously, or even more seriously than just having a global and highly efficient living mode. Most of those components and characteristics are conveyed by multiple languages, some of which are just the ones talked about in this article, facing the destiny of being extinct alongside the ignorance of the public. A state of mind must be made that simpler and easier livings are based on the foundation of complexity and on eliminating the immaterial subtilties, but not, adversely, on extinguish the lights that have been and still are guiding us to the final intelligence.
In conclusion, the loss of the linguistic data has its essence to be concerned about severely, and the convenience, though witnessed alongside the process, should not be the reason we abandon those minority languages.
