Prince Charles and William are working together to encourage others to help tackle the illegal wildlife trade, as part of a week-long awareness campaign in London.
They will take part in a number of activities, beginning on February 9, when a joint video message will be released showing father and son discussing the illegal wildlife trade.
Three days later, on February 12, William will make a special appearance at the United for Wildlife Symposium at the Zoological Society, before attending a reception at the National History Museum to mark the London Conference on the Illegal Wildlife Trade.
On 13 February, both William and Charles will attend the conference, which will be hosted at Lancaster House by the UK Government.
The royals frequently use their unique positions to help highlight the plight of endangered animals — for more than four decades now, Prince Charles has championed action for a more sustainable future.
As well as launching a number of sustainability initiatives, he is an outspoken supporter of wildlife preservation, and became president of WWF UK in 2011.
Like his father and grandfather Prince Philip, William also has a passion for conservation. He has been patron of Tusk Trust since 2005, and has made sustainable conservation a key area of his own charitable foundation.
Through The Royal Foundation of The Duke and Duchess of Cambridge and Prince Harry, he assembled and became president of United for Wildlife, a collaboration of seven global conservation organisations.
