How is pouring DDT down your sink connected to pollution in the ocean and in your body? In this talk from TEDxBeaconStreet Roger Payne, the co-discoverer of the whale song and MacArthur genius award winner, tells how pollution transfers through mammals, from generation to generation. Having led over 100 expeditions to every ocean and studied every species of large whale in the wild, Payne tells us that pollution is the biggest problem faced by whales. With more than one billion people depending on seafood as their primary source of animal protein, it’s very much our problem too. Do you consider yourself an apex predator?
