Language extinction¹

Money influences the development of culture

5 September 2014

Economic development is causing the extinction of some languages, scientists believe.

A study has found that minority languages in the most developed parts of the world, including North America, Europe and Australia, are most at threat. The research is published in the journal 'Proceedings² of the Royal Society B'.

Report

(words spoken in the language Upper Tanana)

This is Upper Tanana. It's spoken by fewer than 25 people in Alaska and may soon vanish. Scientists say that regions like this in North America, as well as areas in Europe and Australia are now hotspots for language extinctions. A study shows that the more successful a country is economically, the more rapidly minority tongues are lost, as one national language comes to dominate³ educational and political systems. 

(words spoken in Bahing)

The team also found that languages in the Himalayas could be at risk, such as Bahing in Nepal which has less than ten speakers. And some found in the tropics⁴ are also disappearing. Rapid economic growth in these regions is thought to be driving this loss. 

The scientists say that greater protection is needed.
