Economics: (un)saviour of the world

Phew! What a day, writing my my entire terms notes - hard work if also very boring. It has however had the benefit of allowing me to think a little.
For I was writing about ecological economics today, and how they are trying to break away from more mainstream neo-classical economics, to traditional haunting ground of the political right (which actually in our society means all 3 of the major parties). But I digress. My point is that for all the good work these people are doing, it wont be enough. What is needed is an entire paradigm shift in thinking (or should that be shift in paradigm thinking). And a few economists, respected though they are, are not going to convince the Bush & Blair administrations that trying to include environmental degredation into our national accounting is a good idea & will aide environmental progress. Perhaps we are doomed after all :(
