The saving a language from an extinction: Is it worthy and important?

What I read

In her paper “ Endangered languages: Strategies for preservation and revitalization” , Loos (2014) talks about the languages spoken by very few native people, clarifying the challenges that face these languages. There are several factors causing a language to become endangered, such as globalization, economics, technology, education policy, and changes in cultural attitudes. Beside the great loss of the extinction of a language for the community in which it is spoken, it is also a loss for the whole world since the language expresses concepts, values, stories, and of course viewpoints that are unique to its community. Moreover, numerous efforts to revitalize endangered languages have been seen in recent years, including the documentation as well as the encouragement of use of them among young generations.

My response 

No person on this earth wants his own language to become extinct or even endangered language. However, sometimes there are compelling circumstances lead to undesired results. Herein, I would like to tell you about one ethnic group from India who left their country because war and came to settle in my country from several years ago. In fact, I do not know when exactly they came to my country, but what I remember is over than 100 years ago. After they arrived to my country, they divided into three smaller groups and lived in three different cities. One of these small group lived in my city.  What I know about them is that they speak different language among them and they are kind to other people. Eventhough their young generations entered the schools who teach Arabic, but they never forgot their own language. Their language is not written in books and also there are not any Alphabets as well, but they learned from each other orally. It is really amazing way to save their own culture and history by keep learning their own language to their grandchildren in so simple way. There are not books, videos, and database to teach, but there are motivations, encouragements, awareness of the importance of language, and of course love of their history and values.          

My question

If your own language become endangered, why is it important to preserve it? and how could you do that?
