This last stage of evaluating stems from active reflection and is to enable us to create an informed discussion of the human responsibility for knowledge, for serving one another, and for protecting essential natural areas. We do this active examination of arguments to evaluate how effective we are at providing each other with the necessary means to protect the earth because nature renders indispensable services to maintain life.
These naturally derived gratuities are called ecosystem services. People are not truly free unless they recognize our interdependence on these services.
These intersecting lines represent the relations that exist among important ideas, which like keystones hold the structure of our knowledge together.
They recall for us Ralph Waldo Emerson's concept of rays of relation that knit together the seen and unseen worlds we inhabit. In this sense ecology connects us in multiple ways to one another, the world, and wildlife.
Rays of relation extend from one thing to another so that reasonable observers see how people, places and things are derived from interdependent actions by one or another symbiotic factors, existing independently from our awareness, yet enable each other to coexist.
John Muir, who was greatly influenced by Emerson reformulated these "rays of relation" when he suggested that when we examine any one item we discover that "everything is hitched to everything else." What he meant was we are all part of–as Fritjof Capra suggests–"the web of life."
