Rising Tide #160 — Louie Psihoyos on Dolphins, Plastics, and More
Academy Award-winning director Louie Psihoyos returned to the Rising Tide Ocean Podcast for a conversation as wide-ranging and urgent as his films. Host David Helvarg sat down with Psihoyos before a live audience during SF Climate Week at the downtown San Francisco studios of KALW public radio — and the exchange didn’t disappoint.

Psihoyos traces his unlikely path to ocean advocacy: a kid from Iowa, drawn early to photography and the sea, who eventually landed at National Geographic — beginning, as origin stories often do, at the bottom, sifting through a garbage dig. From there he rose to become one of the most consequential documentary filmmakers working today, a man who doesn’t just point a camera at environmental catastrophe but builds covert operations around it.
He recounts the making of The Cove, his shattering exposé of the dolphin slaughter in Taiji, Japan — a film that required as much tradecraft as filmmaking — and discusses his latest work, Plastic Detox, now streaming on Netflix, which takes a hard look at microplastics and their alarming effects on human fertility.
The two also range across a broader landscape: adventures, causes for concern, and — perhaps most valuably in these grinding times — reasons for optimism.
It’s a talk worth diving into.
