Taken together, these economic insights explain why the idea of a finite planet is a misdirection. The planet of tangible resources might be finite, and if these resources were all that counted for growth, then we would indeed be heading toward deep economic trouble. But they are not all that matters. In fact, what really matters for growth are the intangible ideas for combining these resources in new and valuable ways.
