The Wild for Life program aims to raise awareness of the illegal wild animal trade happening around the world. Gisele Bündchen, who has served as a UN goodwill ambassador since 2009, has thrown her support behind the project, fronting the stark campaign imagery (below) and revealing her spirit animal (in case you're wondering, hers is a sea turtle).

The campaign encourages the public to log onto the Wild for Life website and take a quiz to find out their own spirit animals, while reading up on the various species on the brink of extinction. Bündchen has urged her social media followers to get on board, writing on her Instagram, "It saddens me that in the 21st century, with all our knowledge and power, we are still hearing stories of wildlife facing the possibility of extinction at the hands of man." She adds, "To overcome this we need a radical change in people's attitude all over the world, so today I'm joining the fight to save these endangered species."
