The Anutans are a group of 300 Pacific islanders that have managed to live in harmony with their environment for nearly 400 years despite living on an island only 1/6 of a mile long. Lessons can be learned from these people that show us how we too can live in harmony with our own environment.

Quite impressive, must have been great seeing them in the water..
