Our grandparents were mostly farmers and ranchers, but now food is produced by less than 3% of the population. This tenuous situation is spreading across the world, from developed countries to the grasslands of Mongolia. The threat to remaining family ranchers in the US and herders of Mongolia has never been more pressing. Can we find a place for the form of livestock production that sustained civilization for thousands of years, or will the pressure of overpopulation and modern production relegate true sustainability to something 'Out of the Past?
