General comment: Here is a grouping of portals that could be added to the economics bar... instead of having just one out side the sphere one... namely business.. Singling out a business related portal on this particular article seems antithetical really to the subject as ecology is the bottom line as regards this subject. I would think a big improvement in the economics side bar could be made by having a section related to other portals.. of which business would or could also be one. I would then not object to the economics side bar at all here, as it would be balanced by other information.
