Tim, in an economy that needs more new jobs every month just to keep even and where mechanization and outsourcing are pushing job retention downwards you bet your ass you need continued growth and you need it desperately if you want to keep the same per person aggregate $ standard of living and avoid a permanently unemployed underclass of American citizens. I think we better go back to the drawing boards on that one. Ed

>>Resources aren't really fixed. Oh sure there is only so much material and energy in/on the Earth or in the universe for that matter and we can't get beyond (or realistically to) 100% efficiency; there is some hard ultimate limit. But the distance from us to that limit is vastly greater than the difference of the cavemen to us.<< That depends on what resources you're talking about. There was a time when the number of fish in the seas was considered to be virtually infinite. We could not possibly ever overfish the oceans. Yet many species of fish that used to be amazingly plentiful, such as the Atlantic cod, have been reduced to such small populations that their very survival is in question. Certainly, they can no longer be depended on to feed even our current population indefinitely. Nuclear energy would seem to be one of the most sustainable sources, but there is now a worldwide shortage of uranium. We didn't even start using uranium until the middle of the 20th century, and we're already in danger of running out. And that's before embarking on a program of building dozens of new reactors to supply ourselves with power. There are other examples, of course.
