It’s similar to hunting coyotes on the prairies. Why hunt coyotes? They’re both considered vermin where they live.
We heard stories from the local PH’s -especially in South Africa - (many of whom are farmers in their “real job”) about baboons taking delight in destroying livestock (tearing open lambs, ripping the feathers off entire chicken coops full of chickens and being particularly deadly to dogs.
There was generally a “hate on” for baboons and a supportive approach to reducing their numbers. That included a large (45,000 hectare) game ranch which catered to wildlife photographers. I spent some time there hunting baboons in the back country. The understanding was that this would help reduce their predation on the local plains game.
