This week we were reminded, again, that the world relies on the free flow of goods at market prices across its oceans to maintain a reasonable standard of living.

Most of the world consumes more food and fuel than it can produce locally. Most of the world's people live from paycheck to paycheck, and entire societies' stability rely on the grain and oil that economically can only be moved internationally at sea.In a story as old has time, there are power who are using that need as leverage by threatening - or proposing to threaten - access to the seas they have access to.

In this case it is the Russians threatening grain shipments through the Black Sea, and the Iranians the shipments of oil and gas.Joining us for the full hour to discuss this threat and how to address it will be returning guest Captain John Konrad.

John is the founder and CEO of gCaptain and author of the book Fire On The Horizon. He is licensed to captain the world's largest commercial ships and has sailed from ports around the world. John has built some of the world's most advanced ships and managed billion-dollar offshore construction projects in some of the world's harshest marine environments. John is a distinguished alumnus of New York Maritime College.
