I think it's a good idea to discuss this topic since it is frequently argued in this forum, by people of the most diverse political inclinations, that the objective fact that physical resources are limited means there is a real constraint on how much the global economy can grow. People who believe in this usually conclude that for one group nations to be rich another must be poor; as the pie is limited we must fight for its slices. I'd like to hear a more qualified explanation of why it is so in their opinion.
Here's my take:
While resources are obviously limited, what we can do with them is not. One liter of oil will get us much further in 2011 than 1920; one acre of land will produce much more food. The return we get from a fixed amount of resources is always growing as our technical progress advances. This is point number one.
Point number two is that we're not even close to fully utilizing all resources at our disposal, and won't be as far as imaginable. We're only using a negligible amount of the total solar energy that hits the Earth (because today it's cheaper to burn oil); but no doubt in the future we could have giant orbiting solar pannels. The potential of fusion power hasn't been tapped yet, but I have no doubt it will at some point in this century. We're quickly heading to a world where most people will live as the western middle class does.
So there's no reason why we can't go on growing our economies for as long as we can imagine. Note that I am not offering any original or insightful thought here; I am merely stating the mainstream opinion.
Now it's time for those who disagree with me say where they think I went wrong.
