In his Sunday New York Times column, Thomas Friedman quotes a climate expert, Joe Romm, who nicely captures a problem that I discuss in my book, and in several blogs posted here(especially "The US Economy Will Shrink A Lot, and It Should.").
"We created a way of raising standards of living that we can't possibly pass on to our children. . .We have been getting rich by depleting all of our natural stocks--water, hydrocarbons, forests, rivers, fish and arable land--and not by generating renewable flows."
This led me to Joe Romm's blog, climateprogress.org, where he has a thoughtful and thought-provoking entry entitled "Is the Global Economy a Ponzi Scheme?" The essay, and that site, are worth a look, and I have added a link to it in my blogroll.
