The increasing popularity of several languages in the modern day has undermined the importance of other minority languages. Although there are some negative impacts attached to this development, I believe this can be more advantageous than disadvantageous.
It is understandable that some popular languages has been replacing or eliminating the existence of other languages worldwide. One notable consequence from this is the gradual extinction of the community or civilization which has been thriving on that language, since language generally contains the identity of such culture. As fewer people are using that dialect in conversational circumstances, it can generate further difficulties for archaeological research, whether how to trace back the origin or unearth some important historical documents related. Another detrimental repercussion from this situation is the loss of cultural diversity on a global scale, thus possibly inhibiting communication and mutual understanding.
Nevertheless, the disappearance of some languages is not necessarily equivalent to the destruction of the world of linguistics as a whole. Firstly, the empowerment of language has been widely related to opening gateway for economic development in developing nations, when in countries such as Vietnam, the youth is encouraged to acquire enough knowledge in English for employment in international business and trade. The positive influence from this trend is also implied in the reduction of labour for translation and research involved in the linguistics world, since the disappearance of some languages means little practical application for studying features of such language, such as grammar used in daily conversation. Finally, it is possible that some languages are not used because of difficult grammatical features or handwriting, which subsequently prevents ease of communication in the casual and professional context. In other words, this happens naturally, which is similar to the natural selection in the animal world.
In conclusion, I am convinced that some languages being spoken more frequently are empowering society as a whole, rather than wrecking havoc to it due to the vanishing of other languages.
