Yes, you are right there, and indeed I have a misconception in my previous posts in so far that while physical resources are limited, this is only a problem if we hit the limit. For example, our brain capacity isn't limited - or at least not at any limit we are likely to reach during our live.
Anyway, regarding your example, you must keep in mind human popularity which was way lower back then. Therefore, they were not hitting the limit. And where you don't hit the limit, there can be growth.
Nowadays, though, we do hit certain limits. Oil and uranium are the most perceptible, I suppose, and therefore they need to replaced by other means. Fusion reaction, hybrid motors etc. all come to mind. However, those things cannot really add to growth because at the same time the old technology is dying when it is replaced. So I guess the question is whether you can find new things which do not touch existing branches. And I think this will become increasingly more difficult, though certainly not impossible.
With that being said, I'm not convinced that capitalism is actually an ideal force to drive changes. That is, because to my perception capitalism drives to maximise profits *in the present*, not in the long run. Oil is an ideal example. We all know that it's going to be gone at some time, even though the actual time frame may vary quite a bit depending on the predictions. Yet we continue burning it at insane rates in cars, and the automobile industry is far behind in producing cars which need less fuel or use alternate means. Simply because it's not as profitable *at the moment*. Yet, oil is used for so much more than fuel. Plastic is all around us, we are short on any material which could replace it, but plastic is made of oil - in the long run it would be wise in every aspect to save oil. Why, then, isn't it?
(Ok, sorry, I guess this has to do now, after all, the topic's still about global warming.)
Edit: Oh one thing, warmi. I think you also have a misconception there - communism is *not* the opposite of capitalism, communism is the opposite of free enterprise economy. And while I do argue capitalism, I don't argue enterprise. Criticising capitalism doesn't make you communist
