For the past decade, Canadians have been split 50/50 on new pipelines — that's changed.

Alexandria has been the source of invention, innovation, and beauty for millennia — capturing the imagination of Napoleon, the Prophet Muhammad and, of course, Alexander the Great.

Homosexuality is a crime in more than half of African countries — a crime punishable by prison sentences. Or in some cases: death. New laws in some states make it illegal for anyone to even advocate for LGBTQ+ rights. These laws bring up questions of foreign influence, neo-colonialism, and the role the international community could and should play in nudging human rights on the continent.

Egg freezing is considered a kind of "fertility insurance" for the future — a way to buy more time to make a decision about having a family. However, as IDEAS contributor Alison Motluk discovers, uncertainty around parenthood is just one of many reasons why egg freezing is one of the fastest-growing reproductive technologies in the world. She explores those reasons and digs into the social politics, gender realities, and big business of egg freezing.*This episode originally aired Oct. 22, 2025.

Renowned natural history writer Robert Macfarlane traveled to Ecuador, India and Quebec, pondering the question of whether rivers are living beings — the premise behind much of the movement to legally recognize the rights of nature. He found that the answer to that question is more complicated and wondrous — and more life-altering and world-changing — than he could have imagined. *This episode originally aired on Sept. 3, 2025.

Even if you aren't a fan of Frank L. Baum's The Wonderful Wizard of Oz, you know about the Tin man, the ruby red shoes and that the dog is named Toto.

For over 125 years, there have been derivative works of Oz, from Broadway musicals, films, comic books and more. IDEAS follows the proverbial yellow brick road to uncover how this seemingly simple story of friendship, self reliance and longing for home continues to speak to us. *This episode originally aired on Sept. 9, 2025.

Ancient history just got an upgrade. Forget the ruins, empires and great thinkers of the Classical period and make way for escaped slaves, subversive pirates, and freethinking religious sects. These nonconformist communities rejected hierarchy and political order in favour of creating a more equitable society.

Author, religious scholar and historian Christopher Zeichmann offers an alternative lens on the Greco-Roman era in his book called Radical Antiquity: Free Love Zoroastrians, Farming Pirates, and Ancient Uprisings.

The yellow traffic light is a perfect example of imperfection — with intention. While driving you have to think fast. Do you speed up or stop, whether that means easily or slamming on the brakes? Every driver has their answer and what lies in the middle is a vast perceptual field. A great deal of thought has gone into the engineering of the ambiguous yellow light, as IDEAS producer Seán Foley found out. He had his own encounter with what he was sure was the shortest yellow light in the world. It resulted in a traffic fine, and gave voice to so many questions.

Travis Stocking is a senior traffic analyst for Durham Region, Ontario

Alfred Mele is a philosophy professor at Florida State University

Ron Usher is a retired lawyer and IDEAS listener in Parksville, B.C.
