Spiritual ecologist

Many years ago, in an experience I will relate another time, I was told to meditate on the term "spiritual ecologist". At the time, I stumbled onto a book by Ken Wilber titled, "Sex, Ecology, Spirituality: The Spirit of Evolution". I remembered reading it as more of a collection of unfocused, rambling thoughts of a man who clearly had insights, but, no cohesive vision to tie them together. Nonetheless, I still was excited to have something to confirm the term had some real world connection. I did a quick Google search and saw 140 hits for this specific term as of today. Seems like someone wants me to look back at the concept again.
