US actor Josh Duhamel has teamed up with charity WildAid to star in its new campaign video, advising the public to avoid buying souvenirs made from threatened wildlife species.

The campaign, which launches tomorrow (June 17) to mark World Sea Turtle Day, sees Duhamel holding a tortoiseshell bracelet made from a sea turtle shell and commenting 'Many of the world's most magnificent animals are being pushed to extinction by the illegal trade in products made from their body parts. If you travel abroad, you may be offered one of these products. They may look nothing like the animal itself, but don't be fooled'.
