These idiots aren't conservationists; they're preservationists & thus cannot see past the "bang = dead animal" scenario.
They have no idea whatsoever as to the money spent on breeding these herds & the cost of their upkeep.
Like many "animal rights" types, they spend all their donations on propaganda whilst hunters & ranchers plough literally BILLIONS into improving, breeding & managing them.
Without private finance, the animals mentioned in the OP's link would likely be COMPLETELY extinct by now & not just in their native habitat, as no African government is either competent or financially able to protect them.
I'm just a little past seriously P***ed off with the bloody bunny huggers.
