It's haunting to realize that half of the languages of the world are teetering on the brink of extinction.

What could be more lonely than to be enveloped in silence, to be the last of your people to speak your native tongue, to have no way to pass on the wisdom of the elders, to anticipate the promise of the children. This tragic fate is indeed the plight of someone somewhere roughly every two weeks.

Cultural survival is not about preservation, sequestering indigenous peoples in enclaves like some sort of zoological specimens. Change itself does note destroy a culture. All societies are constantly evolving. Indeed a culture survives when it has enough confidence in its past and enough say in its future to maintain its spirit and essence through all the changes it will inevitably undergo.

If diversity is a source of wonder, its opposite - the ubiquitous condensation to some blandly amorphous and singularly generic modern culture that takes for granted an impoverished environment - is a source of dismay. There is, indeed, a fire burning over the earth, taking with it plants and animals, cultures, languages, ancient skills and visionary wisdom. Quelling this flame, and re-inventing the poetry of diversity is perhaps the most important challenge of our times.
