"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."
