Rhinoceros poaching continues to be a big problem in South Africa. Poachers take the rhinos' horns because they are used in traditional medicine in many parts of Asia. The number of rhinos killed by poachers has been growing year by year, 499 of them in 2023. Conservationists have tried to stop poaching by removing rhinos' horns, but they grow back in about 18 months. Poachers could do this, too, but it's easier to just kill the rhino and then take its horn. Conservationists have even tried poisoning the horns, but poachers don't care, since the effects come after the sale.
A new initiative called the Rhisotope Project involves tagging a rhino's horn with small radioactive chips, two in each horn. The radiation emitted is not dangerous to the animal, and should last five years. The reason behind the scheme is because international airports, seaports, and many national borders are equipped with radiation detectors as part of the fight against the smuggling of nuclear materials. Sure, the rhino would already be dead at that point, but it would help bust the smuggling rings that support the poachers.
