​​David Helvarg (Host) is Executive Director of Blue Frontier – an ocean conservation and policy group and the author of six books: Blue Frontier, The War Against the Greens, 50 Ways to Save the Ocean, Rescue Warriors, Saved by the Sea and The Golden Shore. He is organizer of ‘Blue Vision’ Summits for ocean activists, Peter Benchley Ocean Awards (with Wendy Benchley), chaired the first global March for the Ocean in 2018 and in 2019 launched the Ocean Climate Action Plan coalition that contributed to the first Climate Action law in U.S. history including $6 billion for coastal restoration and greening ports.

​​Helvarg worked as a war correspondent in Northern Ireland and Central America, covered a range of issues from military science to the AIDS epidemic, and reported from every continent including Antarctica. An award-winning journalist, he produced more than 40 broadcast documentaries for PBS, The Discovery Channel, and others. His print work continues to appear in The New York Times, LA Times, National Geographic, Sierra, etc. He’s done radio work for Marketplace, AP radio, and Pacifica and led workshops for journalists in Poland, Turkey, Tunisia, Slovakia and Washington DC. Today he and Blue Frontier continue to lead media training workshops for ocean scientists and advocates. He is also a licensed Private Investigator, body-surfer and scuba diver.

Louie Psihoyos (Guest) is an Academy Award-winning filmmaker and Executive Director of the Oceanic Preservation Society (OPS). He is recognized as one of the top still photographers in the world, having created iconic images for National Geographic for 18 years, and hundreds of covers for other magazines. Believing that film can be the most powerful weapon in the world, Louie founded OPS with Silicon Valley entrepreneur Jim Clark in 2005.

​An ardent diver and dive photographer, Psihoyos’ mission is to show the world the decline of the oceans–our planet’s most crucial resource. Circling the globe dozens of times on photographic missions, he collects the imagery and stories underlying the compelling issues that challenge and threaten the natural world while connecting with environmentalists who are working to save the planet.
