From timber to cattle and from water to oil to gold, we'll take the ultimate inventory of all the natural resources that the Earth has to offer to uncover the absolute value of the planet. With informative CGI sequences, this Special will calculate the quantity of each resource - how much we've used through human history and how much is left - and put a price tag on all commodities in their raw state, before man has added value through design or manufacture. In the process we'll get a macro view of history by examining how prices and demand for certain resources have changed over time as new technologies make new materials valuable while rendering others useless.
