<p>The prize-winning writer Richard Powers moves from the forests and outer space in his last two novels The Overstory and Bewilderment, to dive into the vast and mysterious ocean in his latest work, Playground. Through the lives of four main characters he explores the ubiquity of play in the natural world, and the role technology is playing in the game of evolution. </p><p>The scuba diving philosopher Peter Godfrey-Smith concludes his three part exploration of the origins of intelligence, with Living on Earth: Life, Consciousness and the Making of the Natural World. As he looks back at the origins of life and its divergence, he places humans within this 3.8 billion year history, and their shared sentience with other life forms, and weighs their current responsibilities on an evolving planet. </p><p>The marine biologist Professor Heather Koldewey takes her responsibilities very seriously, acting to protect the oceans from over-fishing and plastic pollution. One of the world’s leading authorities on seahorses, Koldewey has looked at forming partnerships with others to solve problems, from working with a manufacturer to turn discarded fishing nets into high-end carpets, to creating conservation areas alongside local fishing communities in projects across the Indian Ocean.</p><p>Producer: Katy Hickman</p>
