BAT ULZII DISTRICT, Mongolia, Jul 19 (IPS) – “My son went after his cow. He will come soon. Our work starts as soon as the sun rises — milking the cows, herding the sheep, rearing the calves, and on it goes. There is nothing more difficult than losing cows and calves on hot summer days,” says herder D. Chimiddulam, standing in green grass on one side of a tall wooden fence, looking at dozens of black and white sheep and goats in the enclosure.
