  • End the Year by Refusing Refuse
    Dec 29 2025

    In this year-end episode Holden Hardcastle and Nick Paz do an on-the-ground (actually on the beach) interview with Vince Yuen, founder of 'Refuse, Refuse San Francisco.' During a beach clean-up on the city's oceanfront he discusses the significance of community-led trash cleanups in protecting the environment. Vince shares how his organization started as a personal project during the COVID pandemic and evolved into a city-wide movement aimed at reducing urban litter and its impact on all waterways. The discussion also touches on legislative efforts to reduce cigarette butts and single-use plastics, illustrating how collective citizen action and policy changes are crucial for lasting environmental impact.

    Dec 1 2025

    In the latest episode of Rising Tide, David Helvarg speaks with Peter Gros and Dr. Rae Wynn-Grant, co-hosts of “Mutual of Omaha’s Wild Kingdom: Protecting the Wild,” a show whose origins go back to 1963, when most televisions were still black and white, but wildlife was both more abundant and less understood.

    Today, you can see their Emmy-nominated television show on Saturday mornings on NBC or watch it on Peacock, Amazon Prime, YouTube - so many outlets, you have no excuse not to watch it, once you’ve heard what they have to say on this podcast.

    Peter Gros is, among other things, a wildlife expert, a licensed animal educator, and a 40-year veteran of the show many of us grew up on.

    Dr. Wynn-Grant is a wildlife ecologist specializing in carnivore-human interactions who also focuses on expanding science communications and sustainability. A National Geographic research fellow and author, she joined the show in 2023.

    ‘Wild Kingdom’ is also getting saltier over time with more ocean shows on gray whales, white sharks, coral reefs, and one of our favorites, kelp forests, including their most famous residents, the voracious marine weasels also known as sea otters. So, dive in for a fun and informative interview with these two land and sea stars.
