As already mentioned some want to develop
ecological economics into economics done properly
or see ecological economics as bthe only
heterodox school of economics focusing on both
the human economy as a social system, and as a
system embodied in the biophysical universe
(Gowdy and Erickson, in press). This perspective
leaves very little room, if any, for neoclassical
contributions inside the framework of ecological
economics, whereas others are happy to include
neoclassical contributions.
