Jorgen Randers is an optimist. When I met him in Washington DC in March at a Limits to Growth symposium hosted by the Smithsonian and the Club of Rome, I found him to be a delightful, cheerful man. Yet he has given up on humankind. The biggest take-away from his new book, the latest decadal Limits to Growth update, is that short-term thinking will continue to trump the long-term welfare of the planet, and of the future generations who will depend on it.

But 2052: A Global Forecast for the Next Forty Years is  far from a depressing doomsday read. In fact, based on my own worldview, informed by a decade of researching and monitoring our modern culture’s obsession with growth, Randers paints a far rosier picture of our future than I’m afraid we’ll see. . . .

A few days after last November’s world premiere of GrowthBusters, the program director of Mountainfilm in Telluride asked to see the film. Mountainfilm was planning a daylong symposium on population in conjunction with its annual film festival on Memorial Day weekend, and Paul Ehrlich was urging Emily to screen GrowthBusters at the festival. It seemed like a perfect fit.

In April I was heartbroken to learn GrowthBusters was not on the agenda. Just one film expressly about population was scheduled – a brand new film called Critical Mass. While I was bummed about GrowthBusters being passed over, I was still glad to see the subject addressed at the festival. I felt it was important to support this, and of course was very interested in seeing Critical Mass and attending the Moving Mountains Symposium about population. So I swallowed my pride and made plans to attend. . . .

It would have been nice for me to share today’s guest post with you on Earth Day, as that occasion drove some of these comments. However, maybe it’s even more appropriate today, almost 3 weeks after Earth Day 2012. Did we change the world on April 22? Did you change your life?

Earth Day 2012: What are We Celebrating?

by Ghassan Karam

Many in the world are already celebrating the 42 anniversary of Earth Day and that is understandable. The young idealists who started this movement had a dream, a dream that the citizens of this planet have grown up, opened their eyes and decided that the human species must change its behavior , in all fields, if the planet and all what is on it is to have a chance to sustain its existence and to thrive. Over forty years have passed and the dream is farther away than ever. Actually it is not an exaggeration to claim that the dream is currently out of reach and that the human species has managed to create the conditions that will lead to nothing short of a ruinous outcome. Yes we are beyond the tipping point and in the words of the great James Lovelock we are witnessing “Gaia’s Revenge”. . . .

Karen Shragg is a naturalist in Minneapolis I’ve come to know through World Population Balance. Karen is a sustainable population advocate and is a very active member of WPB’s board of advisors. I might mention I am a huge fan of the work being done by World Population Balance. Explore the organization’s website. Don’t stop here, but do check out it’s Frequently Asked Questions. Very well put together. It would be an understatement to say Karen is passionate about this subject. I invited her to participate in our continuing series honoring the 40th anniversary of The Limits to Growth, and I’m pleased to share what she wrote. It is so significant I feel I should add my two cents, but she covers it quite eloquently and I will leave it to her. . . .

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. . . .
