Craig Foster is the Academy Award-winning director of the documentary My Octopus Teacher.
A decade ago, tired of the city life, he decided to return to his birthplace - the Cape of Good Hope in South Africa - and dive into the wild and beautiful great African Sea forest each day.
His new book asks how can we reclaim our wildness in a world that wants us to stay so tamed?
He talks to Nights about 'Amphibious Soul: Finding the Wild in a Tame World'.
