The intersection of science, politics, and environmental discourse is full of puzzles: why has nuance gone missing from the conversation? Why are heterodox or balanced views often sidelined? And how do echo chambers, alarmist rhetoric, and the erosion of trust hinder lasting progress in conservation?

To explore these questions, I spoke with Roger Pielke Jr., a political scientist well-known for his work on contested science in contentious policy areas, from climate and extreme weather to COVID origins and sports governance.

The concept of rewilding has been applied in various ways, from the simple restoration of a single natural process like removing livestock to allow vegetation to recover, to ambitious proposals to reintroduce long-extinct megafauna. While some applications have obvious conservation benefits, rewilding also raises legitimate concerns, especially about how renewed interactions with reintroduced wildlife like large herbivores and carnivores, might affect human wellbeing, livelihoods, and land use. Rewilding has become a popular and sometimes controversial topic within conservation circles. It has also been gaining traction and growing public and governmental interest as societies search for more holistic approaches to restoring ecosystem processes and biodiversity.

Joining me to unpack what rewilding means, and to explore the potential conflicts and compromises that come with it, is Marine Drouilly. Marine is the Regional Coordinator for Wild Cat Surveys and Research in West and Central Africa with the NGO "Panthera".

Multilateral environmental agreements (MEAs) are negotiated by national governments, but they also include input from various societal groups. One of these groups is youth, and their role in negotiations has grown more visible and coordinated over time. But are these contributions helping to enrich discussions and inspire ambition, or simply adding another layer to already complex processes? And why have separate groups if governments are meant to represent all of their citizens? In this episode, we take a closer look at the place of youth in forums like these — and what constructive and meaningful participation looks like.

My guest is Mika Tan, advisor to the Southeast Asia chapter of the Global Youth Biodiversity Network (among other roles) and a passionate advocate for youth voices in global decision-making.
