The Wabanaki-Acadian old-growth forest is endangered — only one per cent of its old growth is left. The ancient forest, which stretches from parts of the Maritimes and Southern Quebec down into several New England states, is now comprised largely of newer forests, already cut down and logged, over and over. IDEAS explores the rare beauty of 300-year-old trees and astounding biodiversity before it's gone.*This episode originally aired on aired on June 11, 2024.

Our relationship with earth and water is changing in the Anthropocene, says renowned author Robert Macfarlane. Humanity has become a transformative force of planetary proportions, to the point where we are altering the composition and behaviour of the four elements: earth, water, air and fire. He tells IDEAS this has grave implications for the planet and us. *This episode originally aired on Oct. 9, 2024.

The summer of 2026 has been defined by the smoke — and the horror — of wildfires around the world. But what comes after one of these fires? "That isn't the end of the story. That's the beginning of a whole different kind of story," says Nlaka'pamux ecologist Jennifer Grenz. That's why we have decided to follow the long-term story of one 21st century megafire: the 2021 McKay Creek wildfire in interior B.C. Producer Pauline Holdsworth returned in September 2025 — four years after the fire — to find new life emerging from the ashes, and new questions about the road ahead.

In 2021, a deadly heat dome produced a devastating wildfire season across British Columbia. While immediate media coverage often focuses on evacuations and the numbers of homes destroyed, many First Nations say what these fires do to the land in their territories — and the cultural lives of their communities — is often overlooked. "These fires are killing our way of life," says a Tmicw coordinator for the St'át'imc Chiefs Council. IDEAS visited St'át'imc territory around Lillooet, B.C. to learn how 21st-century wildfires are reshaping the landscape — and their consequences for plants, animals, and humans alike.

On the surface, bibliotherapy might sound like another personal wellness trend, but it definitely isn’t. In fact, it’s an approved form of mental health treatment in Canada. And it’s been around for at least a century. In this podcast, researchers Sara Haslam and Edmund King discuss the First World War roots of this practice in the UK. Author Cody Delistraty considers its role in moving him forward in the grieving process. And psychiatrist Martina Scholtens explains why she created an evidence-based reading list online, tailored to a range of mental health diagnoses. *This episode originally aired on June 2, 2025.

We should move away from this idea that childhood should be filled with innocence, safe from the knowledge of difficult things argues Critical Cultural Theorist of Childhood Julie Garlen. Kids do experience difficulty, even in the best of circumstances, and she suggests they need the tools and language to navigate the lives they are living. Constructing childhood as a time of innocence limits children's opportunities for growth and learning. *This episode originally aired March 27, 2025.

Eugenics is seen as a 19th-century idea put into horrific 20th-century practice. But the attraction to breeding “better” humans has a long and persistent history, says Adam Rutherford. The geneticist and science podcaster explains, in conversation with host Nahlah Ayed. *This episode originally aired on January 20, 2023.

That’s what Hanna Pickard argues. After analyzing the scientific research, and working with those who’ve stopped self-destructive drug and alcohol use, the Johns Hopkins philosopher sees addiction as a complex behavioural disorder. She argues it’s driven by individual psychology and social circumstances, and should be treated that way. Jowita Bydlowska and Michael Kaufmann, both memoirists of addiction, weigh in. *This episode originally aired on March 3, 2026.

Guests in this episode:

Hanna Pickard is the author of What Would You Do Alone in a Cage with Nothing but Cocaine? A Philosophy of Addiction (2026). She is a professor of philosophy and bioethics, as well as psychological & brain sciences, at Johns Hopkins University.

Jowita Bydlowska is a writer of fiction, as well as two memoirs of addiction: Drunk Mom, and Unshaming: A Memoir of Recovery, Relapse, and What Comes After (2026).

Dr. I. Michael Kaufmann is emeritus medical director of the Physician Health Program of the Ontario Medical Association. He is a retired family doctor, a retired addiction doctor, and the author of Drugs, Lies, and Docs: A Doctor's Memoir of Addiction (2024).
