Six steps to “getting” the global ecological crisis

By John Feeney:

Some of us who examine and discuss environmental matters are constantly puzzled and frustrated by the seeming inability of elected officials, environmental organizations, and environmental and political writers to “get” the nature of our ecological plight. Could it be they’re simply unaware of the ecological principles which enable one to understand it?

Since some undoubtedly are, and in light of the warnings in the UN’s latest report on the state of the global environment, here is a brief list of axioms and observations from population ecology with which everyone should be familiar. Most are taught in introductory level ecology and environmental science classes. They appear sequentially, so the reader can step logically through a progression which should make clear some of the fundamental elements of the global ecological challenge before us: (more…)

WEAP model on The Oil Drum

[Note update below. Paul’s updated model is here.]

There’s a lengthy discussion on The Oil Drum of Paul Chefurka’s World Energy and Population: Trends to 2100. I mentioned Paul’s paper in the introduction to the previous post here, and recommend it to anyone interested in an excellent, readable analysis of the relationship between peak energy and global population. It goes a long way toward bringing into focus much of the essence of our global ecological crisis.

I haven’t read all the comments on The Oil Drum, but there’s clearly enough material there to keep an interested reader busy for days. Good stuff.
[10/21/07] Update: See Paul’s newer World Energy to 2050. Given Paul’s reassessment of his WEAP model (see this link, but also Paul’s comments below), a few more words are in order. It seems the key conclusion resulting from over 400 comments on the paper on The Oil Drum was that it did not successfully establish a causal link between energy decline and population decline.

That said, I believe the paper has had real value. First, it does contain excellent examinations of some important issues. Second, getting it in front of large numbers of people who could discuss and critique it has moved the discussion of this hugely important topic. We now have some new indication of how difficult it is to demonstrate beyond doubt a link between energy decline and population decline. It remains, of course, a problem of tremendous importance.

This is all very speculative, of course, but if true, it may in time help clarify the role of peak energy in the looming convergence of major ecological problems.[1] It could turn out to provide a smidgen more hope for the human future. Unfortunately, with a number of key ecological crises underway, some form of population crash remains a clear concern. See the comments for more.
[1] Converging ecological problems include climate change, mass extinction, deforestation, aquifer depletion, soil erosion, depletion of fish stocks, and more, all in the context of increasing population overshoot and consequent decreasing carrying capacity.

Earth Needs Renewed Attention to Human Population Growth

Note: The article below, which appeared recently in a number of online publications, was written for a general audience. It should nevertheless be of interest to GIM readers as an effort to spread awareness of the population issue and to dispel a couple of the many erroneous notions surrounding this controversial topic. This version contains a small revision or two but is largely the same as the version which first appeared at Online Journal.

Continued study of our global ecological challenge has meant for me a gradual evolution in my thinking about its dynamics. Population stabilization and reduction are arguably the single most powerful and cost effective means of moving toward ecological sustainability. Yet in just the few months since I wrote this article I’ve become increasingly concerned about the possibility that we’ve missed our chance to avert collapse. (See, for example, in my introduction to Ken Smail’s article on population reduction, Ken’s comment concerning the “temporal problem” with which we’re faced. Or for a detailed discussion, see Paul Chefurka’s analysis of the relationship between energy depletion and population. [10/21/07 – Edit: Note, however, Paul’s reassessment of some of the basis of his analysis.] Or see Jason Godesky’s argument that collapse is inevitable.) If so, reducing fertility rates would serve not as a solution per se, but as a means of softening the landing by sparing future lives. It remains, in any event, the most effective, sensible, humane response to our ecological crisis. — JF


Concern over US population sizeBy John Feeney:

There’s a simple theme in today’s environmental writing. It shows up in titles like “Cut Your Consumption by Switching to Fluorescent Light Bulbs,” “Lawmakers Developing Fuel Economy Plan,” and “Is Wind Power Right for You?”

The trend is to promote reduced personal resource consumption. And it’s a crucial part of the solution to our energy and ecological woes.

But it’s only half the solution. The other half has faded from prominence in recent years. It’s the need to end global population growth. At a time when scientists tell us we’ve outgrown our earth, it deserves our renewed attention.

Population growth received a good deal of press in the 1960s and 1970s, but since then it’s become a taboo subject. China’s draconian one child policy and political pressure from social justice groups who saw the population issue as a distraction from their preferred causes saw to that. Indeed, some writers today even question the contribution of population growth to ecological degradation. (more…)

Weighing the benefits and the deficits of advancements

Administrator’s note: For this post, I’m glad to be able to feature a guest article by Emily Spence. Emily’s essays on a variety of social and ecological topics appear regularly on progressive websites such as, Information Clearing House, and Thomas Paine’s Corner.

This article relates closely to a question we’ve discussed recently on GIM: Would solving energy be enough, in itself, to end our ecological woes, or would such a technological advance bring with it a new set of unsustainable environmental challenges? Emily’s article provides insights which help considerably to clarify this and related issues. Many thanks to Emily for making it available. — JF

By Emily Spence:

During a hot breezy day one summer, my great-grandfather sat on a shady hill alongside of a river that runs through Syracuse, NY. Happy to enjoy such a beautiful moment, he watched young children plunge into the cool refreshing waters and, then, come out to dry themselves in the sunlight and wind. Thus, the idea of the electric hand dryer was conceived.

He developed the first generation prototype and sold the patent for ~ $100 K., a tremendous sum around the turn of the century, so that it could go into production for the good of humankind by removing the need for the same dirty hand-towels being repeatedly employed by different people. In addition, he was happy as he could now afford, due to his lavish fiscal gain, to take Apama, his daughter crippled from Polio, to visit top specialists in many faraway locations.

Suffice it to say that I sometimes look at dryers in public restrooms and wonder whether it is better to use electricity (most of which derives from fossil and nuclear fuels) to dry one’s hands or paper towels (that destroy trees). It is like asking whether one wants paper or plastic bags at the grocery store, as we know that both harm the environment. (more…)

We are so very distracted

DistractedBy John Feeney:

This screenshot is from a talk I’ll be giving at A Renaissance of Local in Lyons, Colorado. It concerns the media’s consistent failure to recognize the most important news story in human history.

The stories making headlines are mostly important. They do need good coverage. There’s no question about that. But their importance pales in comparison with that of our ecological plight. No question about that either.

Ecological issues should be the headlines everyday. Ironically, the stories which do make the front page often have ecological bases which go unrecognized.

Many will disagree with my assessment. Understandably, they feel passionately about issues like the Iraq war. They can’t imagine any other story is as relevant as long as people in Iraq are dying. Yet I believe this reflects a simple lack of ecological awareness. Once one grasps the numbers of lives at risk as a result of looming ecological crises, one’s perspective shifts. Consideration of the potential impacts on global food supplies of climate change as well as the depletion of oil, natural gas, and aquifers is enough to make this clear. Factor in additional problems such as the mass extinction of species now playing out, and it’s impossible to retain any doubt about the media’s ecological blindness. (more…)

When environmental writers are part of the problem

Note: The article below has appeared in several online publications. Though its roots were in an earlier GIM piece, it’s a rather different essay. I hope GIM readers who haven’t previously navigated to it through the link in the Off-site Articles section will find it worth a read.

In recent months there have been signs that some concerned about global sustainability are beginning to recognize once again that population size and growth must have a central place in any discussion of our ecological dilemma. Avoidance of the topic continues, though, among environmentalists who might otherwise raise awareness of the nature of the environmental challenges ahead. With that in mind, here’s a look at how environmental writers are sometimes part of the problem. — JF


Avoiding the truth

By John Feeney:

Something’s missing in today’s environmental discussion. When talking about causes and proposed solutions for our ecological plight, few environmental writers are telling us more than half the story. Al Bartlett, physics professor emeritus at the University of Colorado and long time sustainability activist calls it “the silent lie.” It’s the near universal tendency to focus on the importance of cutting fossil fuel use while staying mum on the topic of population growth.

John Holdren, last year’s president of the American Association for the Advancement of Science, told us the whole story over a decade ago in an article titled, “Population and the Energy Problem.” In it, he observed that the total energy consumption for a country or the world, is the product of population size multiplied by the average per capita energy use. Today, the developers of the “ecological footprint” measure, William Rees and Mathis Wackernagle, echo Holdren when they explain:

[The ecological footprint] for the world as a whole is the product of population times per capita consumption, and reflects both the level of consumption and the efficiency with which resources are turned into consumption products.


News note: radio interview concerning population

I just heard from Bill Ryerson of the Population Media Center that tomorrow (Tuesday, Sept. 3), the Thom Hartmann radio show on Air America Radio will feature an interview with Ed Hartman (no relation), author of The Population Fix: Breaking America’s Addiction to Population Growth. The information I have is that it should air at 2 pm (presumably in North America). I haven’t read the book, but this sounds like it should be worth a listen. Host Hartmann is, incidentally, author of the book, The Last Hours of Ancient Sunlight.

By the way, you can contact Bill Ryerson to get on his email list for a daily article or other item of interest concerning population. Highly recommended.
