The point is that, as with biological species, human languages and cultures need time to change and evolve by themselves. Normally, that process may happen slowly, from one generation to the next, as people find new ways of responding to new challenges and opportunities, and new ways of talking about what’s new.
But increasingly, things are not happening that way anymore. The pace and scale of change have grown exponentially, and so has the intensity of the pressures that economic, political, and social forces are placing on the biocultural web of life. These forces, and the changes they impose the world over, are far outpacing the natural ability of natural and cultural systems to respond and adapt.
By promoting an unsustainable way of life, these dominant forces are eroding the vitality and resilience of the world’s diverse ecosystems, languages, and cultures.
