Why you should listen
Born in Ireland, Simon Berrow has travelled the world's oceans studying albatrosses, seals, penguins, sharks, and more. A passionate scientist and lover of Ireland's natural heritage, he founded the Irish Whale and Dolphin Group and the Irish Basking Shark Study Group.
He is also the inventor of "Simon's shark slime sampling system" -- a mop handle and oven cleaner -- which has proved to be the most effective way of collecting shark DNA for analysis.
The TEDxTalk was filmed at the Science Gallery in Dublin.
