i regularly daydream. africa is one of the places i go to. for instance, i've got hundreds of animals on my iphone. so if i'm at home after a quite stressful day, you can put a buffalo on in the background or a cricket or something like that, and it takes you back into the bush. and it does completely settle you down. >> prince william jokes about re-creating the sights and sounds of africa in his son's nursery. >> i'll have toy elephants around the room, cover it in sort of lots of bushes, and make him grow up as if he's in the bush. >> his love of africa has inspired him to establish the tusk awards to celebrate the commitment of conservation workers. >> i just want them to feel proud and acknowledged in their field.
