Today’s guest post in our Limits to Growth 40th anniversary series is courtesy of Tom Murphy. Tom is an associate professor of physics at the University of California, San Diego. He has simultaneously posted this entertaining conversation on his popular blog, Do the Math. More about Tom after the conversation. While there are economists, like Herman Daly, who believe there are limits to economic growth, there are many more, such as the infamous Julian Simon, who do not. That ratio is, I believe, in the process of changing. We hear from both Daly and the late Simon in the GrowthBusters film. It’s pretty entertaining. But I have to hand it to Tom Murphy. He shares with us here an enlightening and engaging conversation with an economist of Simon’s ilk. Enjoy and learn!     – Dave Gardner . . .

Today’s guest commentary in our series honoring the 40th anniversary of The Limits to Growth Study comes from Paul and Anne Ehrlich. Paul is, of course, famous for penning The Population Bomb in 1968. You might be interested to know that his wife, Anne co-wrote the book. She and Paul have written many more books since then, none as famous and Earth-shaking, but all very important and worth reading. I want to thank Paul and Anne for writing this specifically for our Limits to Growth blog series. I’ve encouraged them to share it as well at the web site of an important initiative they support, called the Millennium Alliance for Humanity and the Biosphere. GrowthBusters is also a participant in that initiative, and I recommend you explore it. . . .

Today’s guest post in our Limits to Growth 40th anniversary series is by Andrew Gaines, co-founder of Transform Australia. I spent a wonderful afternoon sitting with Andrew in a coffee shop in Sydney two weeks ago, plotting the salvation of our civilization. Andrew understands and evangelizes about the need for system change. Check out his Whole System Change Ideas Bank. I appreciate this contribution to our series from Andrew and the good work he’s doing. I expect we will collaborate a lot in the future.

I am a Growthbuster

I challenge the myth that unlimited growth is both possible and good.

Why? Because the plain fact is that unlimited growth will kill us. . . .

Our series honoring the 40th anniversary of the Limits to Growth study continues. Today, a guest post from Rick Heller. Through www.seeingtheroses.org, Rick is helping us recognize the joys of getting unhooked from our unsustainable, growth-addicted ways. Today he offers a report on the Transition to a New Economy conference.

First, let’s pick up our exponential growth demonstration. If you’ll recall, we began with a single grain of wheat in a beaker. Each day of the demonstration, we double the amount of wheat in the beaker. This is equivalent to a growth rate of just under 3% per hour. This makes it a good fast-track demonstration of what’s happening in the real world. 3% annual growth is a common economic objective. About 15 nations have annual population growth rates near or above 3%. Las Vegas, Nevada was growing faster than 3% annually until the housing bubble burst. Last week we left off at Day Nine, with 256 grains of wheat. Today let’s double that: . . .

5oo GrowthBusters Screenings Earth Day Weekend

If you’re subscribed to this blog, the daily posts will continue for just 3 more weeks – until Earth Day on April 22. As Earth Day approaches this year, I sense growing awareness that we are fast approaching Al Bartlett’s one minute before 12, and a sense that it’s time for a re-awakening. Turning off the lights for Earth Hour or pledging on Earth Day to change over to fluorescent light bulbs or hang the laundry out to dry is not enough. We need a society-wide paradigm shift – away from the expectation of MORE, year after year.

Catalyzing that shift is the purpose of my documentary, GrowthBusters: Hooked on Growth. The film was intended to shake our blind faith in the benefits and possibility of everlasting growth. So if you want to do more this Earth Day, in addition to taking our Pledge to Think Small, I ask you to host a screening of GrowthBusters. The more people who see the film, the more are prepared to embrace the end of growth. It may not instantly convert all viewers, but it will at least plant a seed of doubt about the feasibility of a system hooked on growth. . . .
