The adequacy of mineral resources in light of population growth and rising standards of living has been a concern since the time of Malthus 1798, but many studies erroneously forecast impending peak production or exhaustion because they confuse reserves with all there is. Reserves are formally defined as a subset of resources, and even current and potential resources are only a small ...
Reserves are formally defined as a subset of resources, and even current and potential resources are only a small subset of all there is. Peak production or exhaustion cannot be modeled accurately from reserves. Using copper as an example, identified resources are twice as large as the amount projected to be needed through 2050.
