So how do you change paradigms? Thomas Kuhn, who wrote the seminal book about the great paradigm shifts of science, has a lot to say about that. In a nutshell, you keep pointing at the anomalies and failures in the old paradigm, you come yourself, loudly, with assurance, from the new one, you insert people with the new paradigm in places of public visibility and power. You don't waste time with reactionaries; rather you work with active change agents and with the vast middle ground of people who are open-minded.

Donella Meadows: Leverage Points - Places To Intervene In A System

The Marketing Guys, for obvious reasons, are part of the uber-reactionaries.
If a few of them wanted to test the limits of the theory of gravity by stepping out of windows in very tall buildings, I'm sure we could scrape them off the sidewalk and use their remains as starting fertilizer to plant some trees. [/Rant-Off]

Curious, do you expect such a paradigm shift to come about in a more or less orderly fashion or cataclysmically. How many people do we add to this planet a second?

Growing or dying seems to be a natural rule, the shift that would be most disireable would be a change in the nature of economic growth not its cessation. The current system that adds ever more consumers while increasing the supply of cheap labor appears to be near maxed out.

Unfortunately for ever so many is way paradigm shift could well come about when the ever increasing population and ensuing consumption pressure finally blows the pressure release valve.

I have been managing my own little population overshoot by keeping a bunch of bird feeders filled with high energy seed through the winter. It has been great to have all the birds around but the woods are certainly noisier than usual this spring. Can't say what will happen if the feeders aren't supplied next season, but I'm guessing spring would be quieter.

I'm afraid modern civilization has been energizing at the hydrocarbon feeders for quite some time, with an ever increasing number of feeders constantly coming on line. Not to much arguement left against the inability to keep a lot of those feeders filled all that much farther out. It could get a lot quieter shortly after the feeders start going empty maybe just after the noisiest of springs.

"change in the nature of economic growth"

The rest of your post suggests that you understand the basic fact that limitless growth is impossible, so why are you (or really why are we as a culture) obsessed with continuing economic growth forever. Hasn't it already done enough to destroy the living world?

I do believe some sort of continuous sort of economic growth is possible if we soon quit growing population. Substantial moves toward total recycling, true renewables and more efficient technologies could improve (very subjective I know but few who live in places like Sudan would have much trouble with the term) the standard of living for the bulk of human kind. The developed world's economy would necessarily grow as the rest of the world gets pulled up from hand to mouth existence...if this unlikely though to my mind desireable scenario were to be achieved, and decades of substantially different behavior by all that will take, a new definition of what sort of growth (economic, cultural, spirtual, you name the mix, though population growth seems unlikely to be part of a it) human civilization needs to truly flourish could evolve.

Very utopian I know, but what I consider the more likely outcome of what we have I already intimated many times in many different fashions. The chance of such change happenning without cataclyism...well it is really the only bet regardless of the astronomical odds against it as few will be left to pay off and little will be left to pay off with any bets bets made on our failure to change.

For all the problems our headlong consuming society has created in my lifetime I still find this a much less oppressive cultural atmosphere than the one I grew up in during the fifties--the sort of intolerance we had back then I don't want to see again...but the tradeoffs have been immense.

But the anthrofeeders are not going to remain full of cheap energy much longer (not to mention the shortage of watering stations). Change, great change, is inevitable.
