Trees are one of Earth's oldest life forms; silent witnesses to human evolution and the passing of time. Many people today take the presence of trees for granted, unaware of their greater significance in Earth's ecology, their medicinal and nutritional properties, or the veneration bestowed on them by ancient peoples. The Spirit of Trees captures all these elements in a holistic appraisal of Earth's most influential creation, and will captivate readers through the persuasiveness and passion with which the author portrays his subject. The book explores the relationship of humanity and trees, in terms of the trees' natural assets, humankind's cultural interpretations of the forest and particular trees, and the ability of trees to inspire, soothe and sustain humankind.
