Video: Duke of Cambridge tells China: stop buying rhino horn The Duke joined forces with David Beckham and the Chinese basketball star Yao Ming to record a public service broadcast for transmission in China and Vietnam, the key markets for products made from tigers, rhino, elephants and other protected species. The film, in which the Duke tries his hand at speaking Mandarin, was recorded in September but was only released today by the charity WildAid. The Duke of Cambridge said, "We must stop the demand for illegally traded wildlife products within our lifetimes or these amazing animals will be forever wiped from the planet. As a father I want our children to know that rhinos are not just a picture in a book. Poaching is increasing as economic growth in Asia lead to more demand for "luxury" items such as ivory. South Africa's Department of Environmental Affairs reported on November 27 that 891 rhinos had been killed so far in 2013 compared to 2007"s total of 13. David Beckham says in the film: "We can all do our part by sharing this message with buyers of illegal wildlife products. If you do buy ivory, rhino horn, or shark fin I urge you to stop and help us bring these senseless killings to an end. The Duke and his father the Prince of Wales held a conference earlier this year aimed at bringing together charities and other organisations that can work with each other to end the illegal wildlife trade.
