In 2017, the Constitutional Court of South Africa endorsed the commercialization of rhinoceros horns, provided they are sold with a license and are not exported. While the government of the home country to most of the world's population of rhinos, was opposed to this measure, its highest court ruled in favor of the South African association of private rhinoceros owners (PROA), which believes that the ban on horn trade only boosts poaching. In 2016, more than three rhinos on average were daily killed in the South African savannah with poison arrows, spears and mostly automatic rifles, 154 firearms were seized and 680 poachers arrested.
