More people have died exploring underwater caves than climbing Mount Everest, and we know more about deep space than we do about the depths of our oceans. From one of the top cave divers working today - and one of the very few women in her field - Into the Planet blends science, adventure, and memoir to bring listeners face-to-face with the terror and beauty of Earth’s remaining unknowns and the extremes of human capability.

Chris and Chrissy Rouse, an experienced father-and-son scuba diving team, hoped to achieve widespread recognition for their outstanding but controversial diving skills. Obsessed and ambitious, they sought to solve the secrets of a mysterious, undocumented World War II German U-boat that lay under 230 feet of water, only a half day's mission from New York Harbor. In doing so they paid the ultimate price in their quest for fame.

‘Harry’ Harris—Thai Cave Rescuer, joint Australian of the Year—has an unusual idea of fun: he crawls though pitch-black, confined caves, deep underground and usually underwater. To most, that’s a nightmare. To him, it’s recreation. He’s prepared for all conceivable risks, he’s completely focused. And the discipline and danger involved leave him better prepared for everyday life. In this ultimate armchair adventure, Harry takes us into the lives of other ‘risk-takers’, to find out why they do what they do. 

In an age of unprecedented exploration and innovation, our oceans remain largely unknown, and endlessly fascinating: full of mystery, danger, beauty, and inspiration. Bill Streever - a longtime deep-sea diver himself - has masterfully woven together the science and history of Earth's last remaining frontier: the sea.

In making decisions, when should we go with our gut and when should we try to analyze every option? When should we use our intuition and when should we rely on logic and statistics? Most of us would probably agree that for important decisions, we should follow certain guidelines - gather as much information as possible, compare the options, pin down the goals before getting started. But in practice, we make some of our best decisions by adapting to circumstances rather than blindly following procedures.
