Hawaii was an earthly paradise before the white man came Best source I have is Mitchener's "Hawaii," an historical novel, yes; but convincing regarding Hawaii being an earthly paradise before sailors and Christian missionaries arrived.
The diseased sailors ruined the native's health, and the missionaries did even more damage in twisting their healthy minds.
If Mitchener is your source, you should remember that his depiction of landscapes far exceeds his absility to charactize people. His fictional characters those in Hawaii seldom rise above stereotype and his historical characters are inferior biography.
