Interviews: Bartlett and Ehrlich

Below are two interviews worth a listen. The first is with Al Bartlett. The second features Paul Ehrlich. Each is, of course, a leading thinker and writer on a variety of topics in sustainability. (Both, by the way, will appear in Dave Gardner’s film, Hooked On Growth.) You can find other interviews with each, but these are fairly recent as well as engaging. They range across topic including population, economic sustainability, politics, and energy. The Bartlett interview is 72 minutes long while Ehrlich’s is just 19 minutes:

Wars and climate change: national interests versus global emergency

Editor’s note: Abdul Basit is an Indian expatriate living in Kuwait. In this essay he calls on the leaders at the Bali climate talks to put aside the tendency to emphasize narrow national interests, to serve instead the greater needs of humanity as we face a climate change crisis which could threaten our very future. In that context, he observes that wars fought over national interests impede our progress in addressing larger environmental issues such as climate change. We must realize we humans share one earth and that “peace is the most important component in the fight against climate change.”

I regret that I was unable to post this piece earlier in the Bali talks, but it’s message must live on long after these talks and into those to come. Many thanks to Abdul for submitting this important essay. — JF

By Abdul Basit:

This is an appeal to world leaders and the scientific community gathered in Bali, Indonesia for the United Nations Climate Change Conference.

While the global community in general and certain scientists in particular are greatly concerned about the consequences of global warming and climate change in relation to the existence of humanity and habitability of earth, a few nations, like the USA, Israel and some other countries are pursuing the war agenda and preparing for a new round of encounters.Humanity before politics

As the world nations and the UN are seriously considering new regulations and policies to reduce greenhouse gas emissions and are preparing comprehensive measures to counter climate change in the UN Climate Change Summit being held in Bali, the world’s sole superpower and its allies are pondering about enforcing new sanctions against Iran and are openly discussing the prospects of World War III.

What we see in the international arena are the two extremes. On the one hand, we see the ever-increasing signs of climate change like floods, hurricanes, forest fires, inundation of coastal areas due to rising sea-levels, melting glaciers, growing poverty due to mounting climate refugees and reduced agricultural output, threat to extinction of species and biodiversity — all of which are proving a serious challenge to existence. On the other hand, as if these problems and crises are not enough, the major discussions in the international forums and among the media are about the methods to counter the threats of Iran from attaining nuclear expertise.

Russell Hopfenberg on food supply, carrying capacity, and population: follow-up responses to readers’ comments

Administrator’s note: Several months ago GIM was lucky enough to be able to arrange for Dr. Russell Hopfenberg to respond to readers’ comments and questions concerning his important work on the links between food supply, carrying capacity, and population growth. My own summary of that work and its background, along with initial reader comments, is here. Additionally, since I wrote that post, Russ has developed an informative slideshow featuring his ideas. Russ’s responses to those initial comments, and readers’ subsequent questions and comments, are here. If you’re not familiar with the ideas involved and the prior discussion here, those links will help you get up to speed.

Now I’m pleased to post Russ’s follow-up responses to that second batch of reader comments linked to above. To my knowledge, GIM is the only website to have had the chance to present a dialog on this work between Russ and interested readers. The content which has emerged has helped readers better understand these underappreciated ideas. My thanks to Russ for his generosity in participating in this illuminating process! — JF

I’d like, once again, to extend my thanks to John Feeney and Steve Salmony for their help with this discussion. Also, thanks to those who participated in this process by either asking questions, responding to my answers, or reading and integrating this information.

Trinifar: For decades the world population growth rate has been declining — see for example here. As Russ says, “… the declining birth rate occurs in countries that have traversed the DT.” It would be interesting to know how much of that decline is due to DT traversal and how much (if at all) to food supply limits.

RH: Regarding the growth rate, this is absolutely true. Now, let’s take a moment to analyze this reality. A growth rate of 3% per year with a population of 2 billion makes the population 2.06 billion the following year — an additional 60 million people. A growth rate of 2% per year, a 1/3 reduction in the growth rate, with a population of 6 billion makes the population 6.12 billion – an additional 120 million people. That’s twice as many additional people as with the higher growth rate!! At some point, our population size will hit the tipping point of ecological disaster and the growth rate won’t matter. As for the DT itself, the DT is a dependent variable. This means that it is a function of something else. That something else is, among other things, food availability. Also, according to the Brundtland Report, it would take more than ten planet earths to usher a population of 6 billion people through to stage 4 of the DT.

Trinifar: Yet it occurs in DT stages 3 and 4 (as Russ notes above) and that includes the US, Canada, Europe, and Japan — a good portion of the world. Is Russ only talking about the parts of the world in DT stages 1 & 2?

Radio interview

I’ll be appearing this Sunday (12/9) on Free Range Thought, WKNY Radio (1490 AM) out of Kingston NY, with hosts Adam Roufberg and Robert Johnstreet. The show airs at 1:30 pm Eastern time. I should be on at about 1:40. This discussion will likely cover a range of ecological topics including population growth, food production, climate change, and other sustainability related subjects. For those outside the station’s broadcast area an audio file should be posted on the show’s website subsequent to airing.

Jane Goodall on overpopulation

It’s always worth bringing attention to another respected voice calling for action to address population. This brief video is a section of a broader October, 2007 interview with Jane Goodall:

Notice, at the 1:20 mark in the video, Dr. Goodall’s mention of the appreciation villagers showed for a family planning team sent to assist them. This is consistent with what I’ve gleaned from articles on population concerns in African, Indian, and other newspapers.

There are some who hesitate to condone action to address population growth in developing countries on the grounds that it means imposing the values of those in the First World on other cultures. It’s an understandable concern, but is no justification for doing nothing. Dr. Goodall’s remarks suggest we need to distinguish between “imposing our values” and providing needed, wanted assistance.

Grim worldview from the deck of the Titanic

Administrator’s note: Jim Lydecker’s essays have appeared previously on GIM. In this one, which first appeared as a guest commentary in the Napa Valley Register, Jim does an especially good job of tying together succinctly a number of the ecological, economic, and political crises we face. He raises, as well, a troubling question: If our elected leaders are fully aware of the challenges facing us, why are they doing next to nothing to address them?

My thanks to Jim for providing this article! — JF
___________________________________________________________
By Jim Lydecker: Titanic

I have written before that America is like the Titanic making her way through an ocean of icebergs. The captain and his staff keep reassuring the passengers everything is OK.

Standing on the deck, we see the bergs getting bigger and closer. Looking up at the captain’s quarterdeck, I wonder if they know what the hell they are doing? Can they be so stupid to not see the impending crises in front of us? Are they focused only on those directly in our path hoping to navigate our way through, fingers crossed?
Or do they know there is no way out and we are doomed?

This allegory is more true than fictional. America faces a convergence of crises of such magnitude that no amount of financial or scientific commitment may be enough to keep them from ending industrial civilization. The future would be less problematic if our leaders had taken on the crises before they became so large and interconnected.

Well said, Bill

This came up in comments, but I thought it was worth a little more exposure.Bill ClintonFrom Anne E. Kornblut at the Washington Post:

Last week at his library, in a speech at a Slate conference honoring top philanthropists, Clinton sounded almost critical of the presidential candidates, including his wife.

His complaint? None has put the subject of population control in a world with shrinking resources on the 2008 agenda.

“Now, nobody’s going to talk about this in the election this year — in either party — but I ain’t running for anything, I can do it,” he said, saying the world population will be 9 billion by the year 2050.

Among public figures, then, it takes someone no longer nurturing political ambitions to bring up the obvious. Does this mean one day an adult will look down at a child on a bleak, perhaps depopulated earth, and say, “We had a chance to save the earth, but politics got in the way”?

Housekeeping: A bit of travel next week will mean I won’t be able to attend to GIM as regularly as usual. If you leave a comment during that time and it doesn’t show up, it may be caught in the spam filter. Be patient and I’ll set it free as soon as I’m able. Expect a new guest post before that.
