The correct answer to this open question is the following.
Mass media and communications technology can be used to preserve indigenous languages in the Americas in different ways.
According to the graphics attached, we can see that in the Americas, 17% of the languages are lost and 16% are endangered.
This data is critical and concerns not only scholars or historians, but it has to worry all the citizens because part of our history can be erased if indigenous languages disappear.
Mass media can be used to help solve this issue because modern technology has no frontiers. If governments invest in proper technological infrastructure to take modern communications systems to the tribes or far away places where many tribes inhabit, this could be a direct way to rescue those endangered languages. This possibility shows that there are options available. The use of the internet is a great resource, proving that no matter the distance, every member of a society or indigenous tribe can be connected and could take classes on the internet, or listening to news broadcasting systems in their former language, as well as reading publications in their languages.
