 As many as 35,000 African elephants are slaughtered yearly to feed the demand for their ivory tusks.This ivory then goes on to be used in jewelry, musical instruments, and other trinkets.Members of the "Rhino Rescue Project" have implemented a technique to combat rhino poaching in South Africa by injecting a mixture of indelible dye and a parasiticide into the animals' horns, which enables tracking of the horns and deters consumption of the horn by purchasers.
