Daniel-p, you might note, though it's not been very much time yet, how few people have bothered to respond to my query about how many people have actually done anything substantial to reduce their footprint, or even looked into it very deeply. Very few people do, though they'll gibber on about articles like this every year or so.
I completely agree with you that a lot of people talks about reducing their footprint or conserving energy, etc, but that little is actually being done on their part to solve the problem. Buying a new electric vehicle or a more efficient washer/dryer is hardly going to change the world. Few people realize how manufacturing an electric vehicle places just as many toxins into the environment and uses just as much resources in the form heavy metals and hydrocarbon components as manufacturing a typical combustion vehicle. However, most of the work towards sustainable growth is happening behind the scenes with local government and businesses. Many cities and counties have come up with a set of indicators to figure out what is happening and how and which policies can make a difference, also figuring out if former policies made any difference. THe problem is that sustainability as a planning paradigm is quite new. It is founded on long-held ecological principles, but in application it is very new. The problem that I am working on is the fact that many of our ecological and economic problems are at a regional scale, and how local government and industry can effect change incrementally within that region.
I frequent energy conventions and summits and yes, I see a lot of "preaching to the choir" and "amen brothers" when it comes to reitterating redundant environmentalist rhetoric. I like to think that I am not a part of that, and that I try to sift out the bullshit from fact and possibility and how I can make a difference in helping local economies grow sustainably.
