"Arunachal Pradesh should be treated as a major priority on a global scale. Languages such as Basque and Burushaski have attracted high levels of scholarly interest over many decades precisely because of their status as language isolates. Those in Arunachal Pradesh have been completely bypassed. Moreover, although these languages are presently still spoken, their populations are small and pressure to switch to Hindi, promoted in both the media and via the school system, is growing. Probably by no coincidence, Arunachal Pradesh is also a major centre for biodiversity, something which attracts worldwide attention and resources. It is suggested that the little-known languages of Arunachal Pradesh should be given similar priority due to their uniqueness and endangered status."
