Sure, shit happens — and on farms throughout the developing world, where the average person earns less than $1,000 a year, shit matters.
I’m in the Tigray region of northern Ethiopia, scouting locations for a new public television special about world hunger. Here at Abedi’s farm, I’m checking out a kind of septic tank where animal dung is mixed with water. Out the bottom drizzles fertilizer and out the top steams biogas (methane). Join me for a little tour.
