Tangelic Talks welcomes Leonie Joubert, South African science writer, journalist, and storyteller who has spent over two decades following the toxic trails of pollution. From carbon emissions driving climate collapse, to processed food fueling disease, to plastics polluting our ecosystems, Leonie’s work asks a critical question: Who profits from pollution, and who pays the price?

Leonie joins presenters Caroline Steel and Chhavi Sachdev with the BBC Unexpected Elements team to talk about emerging evidence that microplastic pollution is blowing in over one of southern Africa’s most important high-altitude water catchments.

Gugs Mhlungu, host of 702’s Sunday morning show, The Nature Diary, chats with resident conservationist Tim Neary and science writer Leonie Joubert about the environmental cost of disposable nappies and how to reduce it. The discussion hinges on the investigation into the fallout of use-and-discard nappies in the Eastern Cape highlands, which draws attention to a scourge across the region.

Clarence Ford speaks with science writer Leonie Joubert on tackling the environmental pollution & waste of single use nappies, and what this says about the global use-and-discard economy: that consumers are expected to mop up the pollution, when corporates should be turning off the pollution at source.

Leonie joins Marnie Chesterton and the Unexpected Elements team on the BBC podcast as a guest presenter to go on a deep dive into marine biology.

Saskia Falken sits in for Clarence Ford, and speaks with science writer Leonie Joubert on how communal Eastern Cape farmers are tackling nappy waste in the Matatiele municipality.

Lives depend on keeping SA’s old-growth grasslands healthy. They feed our herds, they’re water factories and they mop up carbon pollution, which stabilises the climate. Protecting them from overuse, invasive trees and increasingly volatile weather extremes calls for collaborations that straddle national borders, private fence lines and the boundaries of overburdened commonages.

Leonie contributes to a collage of sound experiences woven together by Erika Heilman for her award-winning podcast Rumble Strip. Listeners sent in recordings of what ‘now’ sounded like for them in January 2025. Leonie had dropped anchor in the New England area of the Eastern Cape when she captured a moment.
