Over on Orion Magazine, Eric Zency gives some thought provoking discussion to our favourite "S" word, sustainability.  Noting both its potentials and drawbacks, he gives 18 points for consideration... it's a damn good read.  Our favourite?  Number 5:

"ECONOMIC SUSTAINABILITY describes the point at which a less-developed economy no longer needs infusions of capital or aid in order to generate wealth. This definition is misleading: for many of those who use it (including traditional economists and many economic aid agencies), “economic sustainability” means “sustainable within the general industrial program of using fossil fuels to generate wealth and produce economic growth,” a program that is, of course, not sustainable."
