Prince William issued the message after attending a screening of Rhino Man hosted via United for Wildlife at Battersea Power Station.
The documentary depicts the coaching of flora and fauna rangers and covers the risks that they face.
It elements Anton Mzimba, a South African ranger who used to be murdered by way of flora and fauna traffickers in July 2022.
Later, commenting on the United for Wildlife tweet, Prince William said: “The tragic homicide of Anton Mzimba is a stark reminder of each day risks that ranger face from the crook businesses in search of income illegally from wildlife.
“@unitedforwildlife and their companions are dedicated to making sure the perpetrators are introduced to justice. W.”
United for Wildlife used to be created with the aid of Prince William and The Royal Foundation in 2014 to shield endangered species from the unlawful natural world trade.
