What unusual method is being used to stop poachers in South Africa?

The use of radioactive rhino horns as a method to combat poaching in South Africa is indeed unconventional and highlights the innovative approaches being implemented to protect endangered species. By making the horns radioactive, authorities aim to deter poachers due to the health risks associated with handling such materials. This strategy not only makes the rhino horns less valuable in illegal markets, as they would potentially expose handlers to radiation, but it also allows for monitoring and tracing stolen horns back to their source. Moreover, law enforcement can use sensors to identify the presence of radioactivity in trafficked horns, effectively bolstering enforcement efforts against poaching.

This method reflects a broader trend towards using technology and unconventional tactics in wildlife conservation, demonstrating an adaptive approach to a persistent problem. Other methods, while potentially effective, lack the unique deterrent effect that radioactive materials can provide.
