What is the value of preserving indigenous languages?

For example: Consider aboriginal languages with rich vocabularies used to describe the natural world.

Aboriginal Languages are diminishing by the second, and evidently in that final moment, a culture is lost forever. Preserving languages in general is important because phrases and traditions are untranslatable in a foreign language. Indeginous languages involve the same idea. Indigenous languages are rarely heard or seen as they are typically dominated by colonial power, in which it is seen as oppressed language. In my opinion, the value of preserving indegenous languages are highly important, because there are many information and discoveries that are within these languages that either are untranslatable or havent yet been discovered by anglo phones. Perhaps it is this way because of their lifestyle, as many aborignals for example work with curing by using herbs and remedies by plantations. Also, through extensive research in the Manchu language for example, indeginous language may preserve past recorded histories. This could potentially be informative and useful to the dominating culture of that specific country. Therfore so far, I have used its importance in terms of history, and medicine/ remedies. Another reason, is that like I stated in the beginning, a culture can be lost forever.

From experience, losing your language can prevent you from maintaining your culture. For instance, a common practice in that specific culture has been said in their language for generations, and the younger future generation won’t comprehend the meaning of why that practice exists because it is no longer said in their langage. Some hidden meanings and way of life and celebrations would be lost in that language.

Lastly, I think the great value in preserving indigenous languages are because in my opinion, that would be considered the mother tongue or root language of the country before colonisation. Therefore, if that indigenous language is lost, then the history of the language would be gone, as the language is connected to the founding of the country, the meaning and way of life would be gone, the the country would be completely foreign and strange to what it once was supposed to be. 

By this, I portray that the language is connected to the root of the country, therefore once another language has been introduced to it, the soul of the country is gone because the language is lost.
