Yes, it is the loss of their natural habit which is the cause of their disappearance as you so rightly point out. Indeed the documentary i talked of pointed this out. Its the spreading of cities and man which is the threat ! I realise that their are arguments put up by these " big game " farms which offer these beautiful animals as moving targets for the pleasure of their customers, which say that the economy of this culling can prevent further damage to their numbers. But i fail to see how the proliferation of these animals can be helped by offering them as " trigger " bait for the rich and stupid. We do need another solution which will protect them and not one that clearly adds to their demise !!
