For most of human history there was one problem with our food: there wasn’t enough of it. But the food system we built to solve that problem — the one capable of feeding eight billion people — is responsible for a third of greenhouse gas emissions. It’s also made poor diet the leading cause of early death globally — ahead of smoking. Producer Mitchell Stuart spent a year asking: what should we be eating instead?

From the earliest days of cinema to our era of streaming, zooming, and scrolling, the screen has become a central part of our lives -- so central that it actually impedes our lives, erasing our bodies, and to hiding from one another. Kim Nelson, film professor and director of the Humanities Research Centre at the University of Windsor, argues in a public talk that remaining connected entails protecting and treasuring the enduring wisdom of the humanities -- literature, history, philosophy, art, and drama. This event was held at the University of Windsor and features an onstage interview between Kim Nelson and IDEAS host Nahlah Ayed.

For more than a thousand years the Oracle of Delphi sat on a stool at the ‘navel of the universe.’ Under a mystical trance, she would offer cryptic predictions of the future. People would wait months, even years, for their chance to ask the Oracle for guidance on matters ranging from reproductive challenges, to family tiffs to when and how to wage war.

While the ritual around her remains shrouded in mystery, her predictions were – strangely – always right. Today our urge to predict the future mirrors the same psychological need that drove leaders to the Oracle at Delphi -- discomfort with uncertainty and deep seeded desire to control the unpredictable.

Bureaucracies were created to get the work done and get it done efficiently, according to 19th-century thinker Max Weber. So why are there more and more meaningless executive jobs that contribute nothing but soak up the pay? IDEAS examines the corporate tendency to "bureaumania.” *This episode originally aired on Sept. 18, 2024.

More than 2,000 years ago, someone sat down and wrote a travel bucket list for the ancient world — suggesting must-see places that we now call The Seven Wonders of the World. It was kind of a Lonely Planet guide of its time, and included the Pyramid of Giza, the Hanging Gardens of Babylon, the lighthouse of Alexandria, and the Temple of Artemis, among others. Historian Bettany Hughes brings monuments and archaeological discoveries back to life in her book,"The Seven Wonders of the Ancient World." *This episode originally aired on Nov. 6, 2024.

Without the Moon, the Earth would be unrecognizable. Across the eons, it has shaped our seasons, our calendars — and even the evolution of life itself. Producer Annie Bender traces our nearest neighbour's powerful influence over humanity — and the planet we call home.

Guests in this podcast:

Charlie Duke is a retired NASA astronaut who walked on the Moon as part of the Apollo 16 mission.

Rebecca Boyle is a journalist, historian and author of "Our Moon: How Earth's Celestial Companion Transformed the Planet, Guided Evolution, and Made Us Who We Are."

Christopher Cokinos is a professor emeritus of English at the University of Arizona, and author of "Still as Bright: An Illuminating History of the Moon from Antiquity to Tomorrow."

Hanif Abdurraqib lives his life heart-forward. His writing is informed by the many losses he's endured, but also by his commitment to "love deeply" and to not let machines do his thinking and feeling for him. Doing so, he says, risks atrophying our hearts and minds. "For me, the cost of a heart that's fraying at the edges is too high."

Abdurraqib is the 2026 Weston International Award winner, presented by the Writers Trust of Canada for a body of work by a nonfiction author. He is a poet, essayist, cultural critic, and author of eight books, including, There’s Always Next Year and A Little Devil in America.
