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:

Population and consumption: both major players

Growing footprint Consider this a working paper of sorts. It adds to the last post here which discussed the relationship between population and consumption. But it’s only a snapshot of an initial bit of online and library research. I hope to flesh out the topic more fully in the future.

At the end of that post I mentioned two issues I had barely touched on, which deserved more attention. They were (a) the question of whether, even hypothetically, we could ignore population growth and count solely on advances in clean energy technologies to escape ecological catastrophe, and (b) the implications of the observation that over the last century global energy consumption has increased more than population numbers. In my view, the former question is the simpler one, and I’ll get to in the near future. In this post I’ll provide some of what I’ve found concerning the latter issue.

The consumption argument

It’s a common observation that, over the last half century or more, resource consumption rates have increased at a faster pace than population size. I’ve seen this observation used to support the view that population growth isn’t as serious an environmental problem as our growing rates of consumption. Sometimes a proponent of this argument presents data showing that the magnitude of growth of total world energy consumption, or of total consumption of a specific resource, is considerably larger than that of population.
