“Trees are ents who moved too slowly and have taken root,” Treebeard explained in the “Lord of the Rings” trilogy, by J.R.R. Tolkein. Treebeard was an ent and being long-lived, had much to say.
Research published in recent years appears to indicate that while ents may be fictional, trees do have feelings and do communicate among themselves, usually along pathways made possible by a multitude of fungi growing at the feet, er, roots of those slow-growing, long-living organisms that clean our air, filter our water and provide the raw materials that form our wooden caves.
