Our economists tell us we produce things, implying that given a high enough growth rate and productivity we can do anything, endlessly. We take two things and we end up with more than we started. This is in opposition to the idea that we take our renewable and non renewable resources (aka gifts of nature) and merely transform them into a different shape. In the latter case, there is no such thing as production or growth. There are resources that you should conserve and there are resources which you should use before you lose them.
