AI and Water are more connected than most people realize. As artificial intelligence continues to expand, the data centres that power it are using millions of litres of water every day to stay cool. This invisible demand is creating ripple effects across our freshwater systems, and ultimately, our ocean.
In this episode, Andrew Lewin uncovers how AI's explosive growth is reshaping global water use. From groundwater depletion and saltwater intrusion near coastal data hubs to desalination discharges harming marine life, the story goes far beyond servers and code. He breaks down how indirect energy use from AI contributes to ocean warming and acidification, revealing that every digital action has a hidden aquatic cost.
Andrew also explores innovative solutions—from recycled and non-potable cooling systems to closed-loop designs that dramatically reduce water loss. With growing global demand for AI, he highlights the urgent need for transparency, accountability, and smarter policy design to protect both freshwater and marine environments.

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.
