Prince Harry is in South Africa warning moves to legalise the rhino horn trade threatens the species.
He has taken an emotional tour of Kruger National Park, walking amongst the remains of countless rhinos, slaughtered by poachers.
The prince says four rhinos a day are being killed in South Africa alone.
"If current poaching rates continue, there will be no wild African elephants or rhinos left by the time children born this year, like my niece Charlotte, turn 25," he says.
Last week, a judge struck down a seven-year ban on domestic rhino horn trade.
