Vlad I bewildered by your statement on people who shoot wild pigs!, do you know how many lambs get killed by pigs?, or the eggs of ground nesting birds?, the damage they do to crops and wetlands?.
And just on hunting farmed animals, I wouldn't do it myself but the only reason these animals are there is because of their value for hunting, without these farmers breeding this stock so a few could be hunted the species would be in a much dire state and solely at the mercy of native poachers..
