Nature used to be in perfect balance - until man interfered. As recently as a few centuries ago, primitive man survived from the products of the land with no serious threat to the ecology. Hunting for food had little impact on wildlife.
But then followed the "ages" of agriculture, industry and information, and with it came interference with the balance of nature. That is water under the bridge. The reality is that we created this imbalance, which obligates us to manage the eco system artificially. Unfortunately ill-informed "anti" groups do not allow logic to influence emotion. Perhaps the most classical example is the debate around elephant culling. How, in this new millennium, can anybody in his/her right mind still demand that the African elephant be left to reproduce and destroy the habitat for all other mammals, birds, fish, insects, micro life and eventually itself?
Recently more and more SA livestock farmers are switching to game farming. Numbers of game have to be managed just like that of live stock. They can either be caught and relocated, or shot. The latter is far less stressful.
Culling of problem animals unfortunately got out of hand in places. For instance, farmers frequently pursue the blinkered termination of jackal, purely since traditionally "jackal" = "bad". Research has it that the Black-backed jackal is not necessarily always inclined to stock predation. However, on typical agricultural land the jackal frequently reigns on the top of the food chain, with devastating consequences to smaller predators, rabbits and ground nesting birds. These circumstances would call for culling in support of biodiversity. (See Super Predator for more about this opportunistic survivor.)
