While down under for the Australian theatrical premiere of GrowthBusters, I had the good fortune to spend several hours sitting on the porch of George Trembath’s home near Maleny, sipping tea and coffee and having a deep conversation with George (of Pachacuti Project) and ecological economist Richard Sanders. I jokingly called it the Maleny Summit. I invited Richard to share some thoughts with us for my blog series honoring the 40^th anniversary of The Limits to Growth.

I’m glad Richard chose to write about “decoupling.” We cling so tenaciously to our dogma of everlasting growth that we dream up fairy tales to explain how we can overcome physical limits. One common tale is the idea that economic growth can occur without increasing extraction of natural resources and emission of waste. This notion is called decoupling: economic growth is decoupled from growth in natural resource consumption. Some degree of decoupling has been occurring as our economy emphasizes services over manufacturing, and as we increase efficiency. It’s been happening at a very slow rate, however. . . .

On the plane a few weeks ago I read an opinion piece that begged for this critique. The Ideology of Catastrophe (Wall Street Journal, 10 April, 2012) was written by Pascal Bruckner, who fancies himself a philosopher. He is certainly not a social or physical scientist.

His piece attempts to discredit those who warn our civilization of dangers ahead. I’m not sure why, but a good many folks do feel a compulsion to flee the bad news. I’ve come to accept that, and I try not to condemn people just because they can’t handle the truth. But it does get my dander up when such Pollyannas try to drag the rest of civilization down that ignorant path with them. I’m not saying there isn’t a place in the world for optimism and good news. I’m just saying we absolutely must also be realistic and not ignore warning signs. . . .

“The current human trajectory of growing population and rising consumption is simply not sustainable.   Something has to give.”

I had originally intended to end our series honoring the 40th anniversary of The Limits to Growth (the landmark MIT study commissioned by the Club of Rome), on Earth Day. I have so much good material yet to share, and the warnings provided by The Limits to Growth are so important, I’ve decided to extend the series indefinitely. I will now cut back on the frequency of posts to no more than once or twice a week. Incidentally, the Club of Rome is also stepping up the conversation this year about limits. I recommend you explore the Club’s Change the Course website. Today I’m sharing commentary I invited from Robert Walker, president of the Population Institute. Bob is extremely knowledgeable in the population and public policy arenas. His views are published regularly on Huffington Post, and this commentary should also appear there soon.  – Dave Gardner . . .

Imagine sitting in your home office this weekend having a cup of coffee with Deepak Chopra, Archbishop Desmond Tutu, Bill McKibben, and Joan Blades.

That’s just what you can do, thanks to my good friend Steven Zuckerman. Over the next two weekends he’s bringing some of the world’s most innovative thinkers to you – via the Better World Forum.

This forum brings together participants across six continents and over 80 nations around the world, to discuss cutting solutions for unprecedented cultural, economic, environmental and political changes that are happening in our world today.

Thirty-six sessions will explore topics like enabling human and civil rights, new media engagement, new economic models and creative financing. You can simply listen in, or you can fully engage and participate in discussions following the presentations. . . .

One hundred years ago April 15, the Titanic disappeared beneath the icy waters of the North Atlantic. Several have marked this anniversary by noting the similarities between the Titanic and human civilization. In Titanic: The Final Word with James Cameron, on the National Geographic channel, James Cameron, director of the blockbuster film, Titanic, aptly turned the event into metaphor:

“Part of the Titanic parable is of arrogance, of hubris, of the sense that we’re too big to fail. There was this big machine, this human system, that was pushing forward with so much momentum that it couldn’t turn, it couldn’t stop in time to avert a disaster. And that’s what we have right now.”  He continues, “We can’t turn because of the momentum of the system, the political momentum, the business momentum.”* . . .
