In our latest episode we talk with Ocean and Polar Explorer Don Walsh. A Retired Navy Submariner, as a young Captain he and Jacque Picard became the first 2 humans to reach the deepest part of the ocean – 7 miles down in the Challenger Deep aboard the bathyscaphe Trieste.

He talks about their journey and a near disaster, why ocean exploration didn’t go on to compete with the space race and today’s new generation of deep ocean explorers.

Don also gives his unvarnished take on proposed deep-sea mining and the failure of the UN International Seabed Authority to do its job protecting the ocean depths.
