John Muir is a man with a mission. He needs the world to understand that trees are not just pretty LIVING things that root themselves and never move. They are in fact life itself. Trees provide habitat and fresh air so why would we not treat them sacredly. If all of sudden every tree was gone do you think we would survive for long? Hell No! This reading reminded me of an adult version of The Lorax. This reading is a warning sign, a reality check. The image of sacred trees is a very goddess/ god like image that should very well be taken into account. If after you read John Muir and still feel nothing toward the enviornment and wanting to protect then you have no soul!
