The Prince of Wales and The Duke of Cambridge talk about the unprecedented levels of killing of endangered species like elephants, which are killed at a rate of 100 per day. They also highlight the grave threat the illegal wildlife trade poses to the economic and political stability in many areas around the world and make a plea for the public to support those organisations that are working to put an end to the trade.

They end by speaking the phrase "Let's unite for wildlife" in Vietnamese, Mandarin, Swahili, Spanish, Arabic and English.
