The Good, the Bad and the Ugly

Martin learns about animal exploitation - the good, the bad and the ugly. The actor visits Sri Lanka, where fishing for manta rays is legal, but a turtle sanctuary offers hope. In Thailand, he learns more about silk production - as well as a more animal-friendly alternative - and on the Australian Friday Island, he is shown the delicate art of growing pearls. Finally, in the Abrolhos islands, Martin learns about the most valuable catch in Australia's waters.
