    Just what is meant by 'organic carbon'? Is this carbon currently
    present in organic chemicals of various sorts?

    Otherwise, there is approximately 52 atmospheres worth of carbon locked
    up in the earth's limestone deposits.

    I have read in National Geographic pieces on the water supply that all
    life on earth (which is allegedly 75% water) comprises something like
    0.1% of all water on earth.
