Genghis Khan must have needed a lot of horses that produced a lot of carbon, especially running around a lot.

Each man in the Mongol Army went into a campaign with at least five, and usually eight or more horses. Then there’s the camels used to haul supply carts [ditto yaks], and the camels used by each Tuman commander’s naccara drummer.

I just finished a 1928 tome on Ghengis Khan and the Mongol conquests. It’s estimated that his armies were in the range of 300,000 in size total. Each warrior had a string of ponies. In the distance runs they could travel 100 miles/day as a unit by changing horses.

It’s not inconceivable that in the first few years of conquest the Mongols went through a few million ponies.

Horses are only 25% as efficent at converting cellouse to calories as are cows. This number of horses would have produced three times the amount of poop that an equal number of cows would have produced.
