There is a very good Special Report on economic growth and how (un)sustainable it is over at the New Scientist website. You can read some of it for free. I'll be off to the library to read the rest.
Hat tip to Chris Rose for bringing it to my attention and in his words:
"It's the fundamental difference between us and the ConLabLibSNPPlaidSocialistSect conflation whose ultimate economic (ecological) illiteracy we need to be hammering in the run up to the General Election."
