Half of the World's Languages to Disappear

There is something sad about this:

"MAPUTO, Mozambique - A U.N. Conference on Trade and Development report on protecting traditional knowledge argues that beyond a devastating impact on culture, the death of a language wipes out centuries of know-how in preserving ecosystems — leading to grave consequences for biodiversity.

The United Nations (news - web sites) estimates half of the world's 6,000 languages will disappear in less than a century. Roughly a third of those are spoken in Africa and about 200 already have less than 500 speakers. Experts estimate half the world's people now use one of just eight languages: Chinese, English, Hindi, Spanish, Russian, Arabic, Portuguese and French."
