Should we revitalize Okinawa language?

If you are in a position to make suggestions for a language policy change in Okinawa, how would you convince people in the administration to revitalize languages in Okinawa. Alternatively, what would you suggest if you believe revitalization is not possible or important.

You should integrate all the materials listed below, and should refer to one or two specific arguments/views presented in them. State your citations clearly.

(a) class discussion
(b) Language Death by Crystal
(c) all other reading assignments (Shinzato, Heinrich, Harrison, Glenoble)
(d) the UNESCO website
(e) the Language Matters video (we suggest you watch it sooner than later)
