Animals affected by climate change are showing us how fragile our ecosystems have become. In this episode of How to Protect the Ocean, host Andrew Lewin speaks with Dr. Helen Killeen, a marine ecologist whose research connects seabird reproduction to shifting ocean temperatures, prey diversity, and climate pressures across the northern hemisphere.
Animals affected by climate change, from seabirds in the Arctic to those in the Pacific, serve as living indicators of ocean health. Helen explains how changes in prey diversity and warming oceans disrupt seabird breeding success, what this means for food webs, and why protecting biodiversity can help stabilize marine ecosystems. She also shares her journey from high-school science teacher to marine researcher, revealing how curiosity and adaptability are essential traits for anyone working to protect our planet.

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
