At $65k, a kilo of rhino horn is worth more than its weight in gold, making the animals a prime target for poachers.
In South Africa, conservationists are preemptively cutting off rhino horns in an effort to actually save them.
Like fingernails, the horns will grow back after being cut. The practice doesn't come without controversy; rhinos without horns are more susceptible to injury during a fight, and tranquilization can carry risks.
Between 2007 and 2014, rhino poaching in South Africa increased by more than 9,000%.
