Of the 4-middle lesson-vocation strands, Ecology is programmed in the Professional-Ego; this further subsets into Physical, Living and Human Professions (body, soul, spirit). Ecology is in the Living Professions strand; it is a study of the ‘soul’ of the earth. So the Ecology Block should continually emphasize the career path aspect. What is an ecologist? Who employs them? Government? Business? Self-employment as consultants? Also of interest are training and qualifications; career prospects. Of course, during this block we will also study what ecology is now and how it has been defined in history.
