Environmental Economist Find!

Recently I have been searching for academics or leading professionals with a similar perspective to mine in the environmental field. This of course has by all means been difficult due to the overwhelmingly large lack of economic knowhow/whowhat within the environmental movement. In spite of this I have been able to locate through the complex workings of the internet one Robert Costanza. Robert has published 300 scientific articles in journals ranging from Science to Nature to even The Economist and from what I could tell, I think he has his head on his shoulders. I am currently reading his article entitled "Social traps and Environmental Policy," I'll get back to you about what I think.
