Due to colonial neglect and historical isolation, the Pacific Islands, home to the world's most diverse range of indigenous cultures, continue to sustain many ancestral life-ways. Fewer than 6.5 million in all, the peoples of Oceania possess a vast repository of cultural traditions and ecological adaptations. Papua New Guinea alone is home to one-third of the world's languages - about 780 distinct vernaculars. Oceania thus has the most to lose, culturally speaking, from the pressures of global political and economic change.
