Camel Meat, Milk, Hides,and Hair are valuable products. Why the rush to wanton slaughter? The decomposing beasts will release a hell of a lot more noxious gases than the live ones do.
Why not just geld a few million of'em, and harvest all the young for a while. (Can be done chemically with hypodermic darts almost as easily as shooting the buggers.) And what about their feral goats? Their feral cats? The Rabbits? Stand-by for another Left Wing Ozzie wank!
