While climate action is widely acknowledged as crucial, many struggle to live fully sustainable lives. As individuals, does it matter how engaged we are with climate action? Who is ultimately responsible for��addressing global challenges like climate change?

In this episode, the hosts are joined by Dr Scott Hanson-Easey from the School of Public Health at the �Ӱ�ֱ�� of Adelaide, to explore the often-discussed gap between knowledge and action in addressing climate change. Drawing on his background in��health promotion, science communication, psychology, and social policy,��Scott shares fascinating reflections on why people’s behaviours often fall short of their ideals and discusses the kinds of contextual transformations that could help individuals better align the two, paving the way for more meaningful and sustained climate action.

Feeding eight billion people can feel like an overwhelming challenge. In our globalised food system, decisions made in one part of the world can ripple across borders and impact lives elsewhere. So, what can we do collectively to ensure everyone has access to fresh, healthy food?

In this episode, Professor����and Dr��, as they speak��speak with , a fellow human geographer from the �Ӱ�ֱ�� of Adelaide. Drawing on his extensive research into environmental and agricultural risk management, Doug shares insights into food insecurity across different contexts, the threats climate change poses to both human and ecological stability, and why recognising food as a human right is more important than ever.

While there's no doubt that moving away from fossil fuels is essential for the planet’s future, it’s equally important to ask: what exactly are we transitioning towards? Wind and solar energy may be renewable and abundant, but can we say the same for the materials used to build wind turbines and solar panels?

In this episode, Professor Melissa Nursey-Bray and Dr Ariane Gienger are joined by Dr Rachelle Kernen from the �Ӱ�ֱ�� of Adelaide’s School of Physics, Chemistry and Earth Sciences. As a geoscientist specialising in hydrogen and critical mineral deposits, Rachelle brings a unique perspective on every stage of renewable energy production. She explores the challenges, innovations, and policy shifts needed to make clean energy truly sustainable.

Failing to act on climate change and biodiversity loss is a profound injustice, as those least responsible often suffer the most. Yet even well-intentioned climate action can be unjust if it inadvertently reinforces the very inequalities we seek to dismantle. So how do we navigate this complexity on the path to a truly sustainable future?

In this episode, Professor Melissa Nursey-Bray and Dr Ariane Gienger speak with Associate Professor Kristina Sehlin Macneil, Deputy Director of the Várdduo Center for Sámi Research at Umeå �Ӱ�ֱ�� in Sweden. Drawing on her extensive research into Indigenous experiences with energy production, Kristina sheds light on how the green transition is affecting Sámi reindeer herders and shares their vision for more meaningful inclusion in the projects that shape their lands and lives.

We are witnessing biodiversity loss at an unprecedented rate, with species vanishing faster than at any time in millions of years. This crisis poses serious risks to both people and the planet. In response, the global community has committed to protecting 30 percent of the world’s land and water by 2030. But will this be enough and how realistic is it that we’ll reach this goal?

In Professor Melissa Nursey-Bray and Dr Ariane Gienger's final episode, they turn the conversation inward. Drawing on their research into community-based conservation across �Ӱ�ֱ��, they discuss why biodiversity is essential for all life on Earth, explore the strengths and shortcomings of protected areas as conservation tools, and consider the role of global agreements like the Global Biodiversity Framework.

They also reflect on the conversations they've had throughout the series, and what they’ve revealed about the progress made—and the work still to be done—on the path to a more sustainable future.
