Rob Stewart is the award-winning director of Sharkwater. His provocative documentary challenges the age-old image of sharks as man-eaters and suggests the real villains may be those who kill 100 million sharks each year.
Did you know that sharks have been swimming in the oceans for 420 million years and survived five major extinctions?
"Ordinary people have always made a difference and changed the world and that's what it's going to be in the future."
