In South Africa, the demand for rhino horn is at an all-time high, and the black market price of around $55,000 per kilogram has definitely led to an increase in poaching.

Now elephants could be the rhino's unlikely protector. There are plans to use the elephants - with their acute sense of smell - to halt poachers in their tracks.
