Researchers in South Africa have embarked on a groundbreaking project to combat rhino poaching by injecting radioactive material into the horns of 20 rhinos. The aim is to utilize radiation detectors at national borders to detect the horns and help authorities arrest poachers and traffickers. The project, led by Professor James Larkin from the University of the Witwatersrand, involves veterinarians and nuclear experts carefully inserting isotopes into the horns of rhinos after they are tranquilized.
The global rhino population has drastically declined from around 500,000 to 27,000 due to the demand for rhino horns on the black market. South Africa, home to an estimated 16,000 rhinos, experiences over 500 rhinos killed annually. The researchers hope this innovative approach can be replicated to protect other wild species vulnerable to poaching.
While the idea has received some support, critics, including Pelham Jones of the Private Rhino Owners Association, have raised ethical concerns and doubt the effectiveness of using radioactivity to deter poachers. Professor Nithaya Chetty, dean of the science faculty at Witwatersrand, emphasized that the dosage of radioactivity used is minimal and extensively tested for any potential negative impact on the animals.
The project has faced challenges, but the researchers are determined to find new and effective ways to combat poaching and trafficking of endangered species. With the global rhino population at risk, innovative solutions are crucial to protecting these iconic animals for future generations.
