Unbounded economic growth destroying biodiversity

…we can’t have more of everything instantaneously

…increasing takeover of the ecosystem is the necessary consequence of the physical growth of the macroeconomy

…consider telling the economist to go to hell

Last month I had the privilege of listening to Rob Dietz of the Centre for Advancement of the Steady State Economy (CASSE) when attending the 2010 International Congress for Conservation Biology. He introduced the CASSE and their mandate – to promote stable or mildly fluctuating levels in population and consumption of energy and materials. This is the steady-state economy.

I’ve hinted before that our essentially linear economy (natural resource exploitation -> transport -> manufacturer -> redistribution -> sale -> consumption/use -> disposal (discussed in a very easy-to-understand way in the Story of Stuff) is not sustainable in the long term because of the finite resource base of the planet (think trees, coal, oil, arable land). My colleagues and I have even shown analyses based on hard data demonstrating that total wealth is the ultimate driver of environmental degradation at the country scale.

So, it is my opinion (and a growing number of others‘) that we need a new way of measuring economic prosperity, or the world will enter a state of permanent financial crisis. The mantra of constant economic growth is simply unrealistic as our human populations continue to expand. This is a very simplistic statement and on the surface an apparently impossible goal; however, people who put together the CASSE believe it is achievable.

It is for this reason that I have been communicating with Rob Dietz and others at CASSE about reposting some of their excellent essays on ConservationBytes.com. Please feel free to comment here on the subject matter because the CASSE people will be monitoring. I hope we can expand the readership and support base, and eventually start to convince politicians that growth will eventually kill us and a good slice of the planet’s biodiversity.

So with that, here’s the first repost by Professor Herman Daly entitled “Opportunity Cost of Growth“: Read the rest of this entry »
