If the giraffe species is unable to be harvested sustainably and its products sold to produce income, there will be no reason for game farmers to keep them.
Their natural range in the wild is shrinking rapidly due to the human population explosion in Africa, NOT HUNTING.
Soon (if not already) the only territory which will be available to them are protected areas. In those areas, their numbers will expand beyond the habitat carrying capacities. In that case, they will need to be culled and their products sold or sold live to private landowners. Game farmers will only keep them if they can harvest them to produce income.
Either way, they will only survive if their products have value to Africans.
To have this logical survival imperative interfered with by the anthropomorphic emotive animal activists, who do not understand the natural world, is unacceptable.
