Another round of global climate talks is taking place at the COP30 summit, but some are questioning whether there is much point to these gatherings. We bring people together who have decided to take their own action. One guest, Gwynn, suggests the best way to save the planet is to not have children. She has even had surgery so she cannot get pregnant. “Forests and oceans and prairies are being destroyed so I can exist, so I can have my life,” Gwynn tells us. “I decided that I didn’t want to do that, I didn’t want to continue that, and I realised that the most impactful thing I could do is to not make more people.” Gwynn, who is in the US, is joined in conversation with another environmental campaigner, Maja in Sweden. She has three children. We also explore what happens when families disagree about the environment. And, we hear from an airline pilot, Rich, and his son, Finn, a climate activist. Can they find common ground?
