Dr Roger Payne is a person who believes that whales are one reason why life on this planet is worth saving.  He's been awarded the Third Dawkins Prize for Animal Conservation and Welfare and has just given a bleak but truthful picture about the whales he's dedicated his life's work to, at an audience in Oxford, titled: "Winning Battles and Losing the War."  Dr Payne and his scientific crew have proved that man-made chemicals have penetrated the marine food chain to dangerous degrees.  As one billion people depend on food from the sea the health of our ocean determines also their health, our health. Dr Payne is trying to raise awareness of this issue which urgently needs addressing by decision-makers.
