Wild, right? Scientists in South Africa are injecting rhinos’ horns with a safe radioactive material so customs can spot them if they’re smuggled. The hope? To finally stop poachers from killing these endangered animals for their super-valuable horns (worth more than gold or diamonds!). Only 27,000 rhinos are left worldwide, so this high-tech move could be a game-changer for conservation. Would you support more radical ideas like this to save wildlife? #Science #rhino #conservation
