"Language is not simply a dialect but it represents a Culture, Ethnicity and Tradition"

As per article published in The Indian Express dated May 16, 2020, Mr. Vineet Upadhyay has rightly raised his concerns over the shrinking usage of major languages associated with Uttrakhand, Like Kumaoni, Garhwali, Jhaunsari etc. Other indigenous languages of the hill state include Tharu, Jan, Rangpo, Darmiya, Byangsi, Raji, Chaudangsi and Rawat among 17 spoken in Uttarakhand alone. 

Many of these regional languages along with Kumaoni and Garhwali have been accorded status of endangered languages by United Nations Educational, Scientific and Cultural Organization (UNESCO).

Reasons:

1. Economical dominance when lack of jobs and poverty forced people to migrate towards cities or towards other regions thus dispensing them out from geographical limits.
2. Cultural dominance because literature and higher education is available only on majority language i.e. Hindi or Sanskrit.
3. Political dominance occurs when education and political activity is carried out only in one of the official language Hindi.

I think the regional languages of any region or state should be conserved because of the beauty of that region is associated with those languages. These languages tells us about the culture and importance of the state through their literatures.
