Hi List, I'm a little concerned with this emphasis on limiting economic growth. It seems to me to be to be, politically, a losing proposition from the start, and I'm not sure the underlying premise is entirely valid. Of course there have to be some ultimate limits on economic growth, but the average person who wants a better life sees economic growth as a positive. Is it possible for all those people to have better lives without net environmental damage? It would seem to me that, at least in a developed country like the US (where much initial damage has been done) the answer could be yes. The resources and capital at the bottom of the economy don't necessarily have to grow for the economy to grow, do they? Instead, the relative values, uses, and efficiency of use of the resources can change. Presently, the economy is fueled to a large extent by consumer purchases of products, most of which use natural resources and are basically disposable. What if manufacturers were to largely switch to 'greener' products that also lasted longer? This would mean purchases through the year would be less, and presumably the economy would shrink. However, it seems that rises in other sectors, such as services, education, and food could make up the shortfall and allow average standard of living to rise, albeit under a somewhat different value system where people buy more durable and efficient goods, are better educated, eat better, and live closer together on average.
It seems to me that it would be much more politically effective to take a stand against wastage of natural resources, energy inefficiency, and the like than to decry economic growth. Perhaps the scenario I'm suggesting will lead to less economic disparity among people, and resulting slower or no net growth, but an emphasis on limiting growth per se seems ineffective to me.
