This brief volume discusses the mineral resources upon which modem civilization is built. Take away these minerals and humanity will rapidly return to the stone age, with its greatest concern depletion of flint (also a mineral). It would, of course, result in about a 99% reduction
in population. In other words, approximately 99% of the worlds population is 100% dependent on minerals for its existence.
