Grossly ambitious and rooted in scientific scholarship, The Other Dark Matter shows how human excrement can be a life-saving, money-making resource—if we make better use of it.
The average person produces about four hundred pounds of excrement a year. More than seven billion people live on this planet. Holy crap!
Because of the diseases it spreads, we have learned to distance ourselves from our waste, but the long line of engineering marvels we’ve created to do so—from Roman sewage systems and medieval latrines to the immense, computerized treatment plants we use today—has also done considerable damage to the earth’s ecology.
