Hawever,for the people of Vanuatu,land diving is not a game.This ritual has an important meaning in the life of the people.Men and boya as young as seven dive from towers as a sign of courage and strength.They believe that if a diver's hair touches the ground,the action will fertilize the grouna and will help produce a good crop of yams.So,every year,in early April,islanders begin building at least one tall wooden tower in each village.
