Ethnobotany is very important because it traces the development of humanity. Even the most ancient of civilizations relied upon agriculture and the domestication of certain plants for forage, medicinal, fiber, culinary and dye purposes. Ethnobotany also traces the development of modern Medicine and Herbalism along with the Paper, Chemical & Rubber Industries. It traces the origins of Spiritualism and Shamanism. The mythical Tree of Knowledge of the Bible may have been turned long ago to desert dust during the many wars of the Old World, but it thrives in the peaceful verdant rainforests of the New World, where it has been used to gain knowledge of God, Nature & our Ancestral Relationship with the forest for perhaps 10,000 yrs.
