Cultural diversity is a reflection of people's connection to their local environment, to the living world. Centuries of conquest, colonialism and "development" have already eroded much of the world's cultural diversity, but economic globalization is rapidly accelerating the process.
Cultural diversity is more than appearance, more than folklore, song and dance. It is the embodiment of values, institutions and patterns of behaviour. It is a composite whole representing a people's historical experience, aspirations and world-view. Deprive a people of their language, culture and spiritual values and they lose all sense of direction and purpose.
