    This consumption also raises the quantity of plant matter which must grow in
    the first place to account for the coal we see. Thus in the calculation I
    presented the other day, if half of all wood is eaten, one must have 2
    world's full of tropical rain forests.

    The quantity of coal in John Hunt's work is all in the world, including thin
    seams. The BP Statistical Review of World Energy reports that the reserves
    of coal are around 1/15 of the total quantity Hunt reports. For those who
    don't know what reserves are, they are the amount one can economically dig
    out of the ground.
