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.
