Our relationship with food is unhealthy. While nearly 2/3 of English adults and 1/3 of children struggle with extra weight problems, there are currently around 2,500 food banks operating in the UK.

What's gone wrong? Why do we so struggle with food? And whose responsiblity is it to feed us anyway?

In this week's episode, Nick Spencer speaks to author Pen Vogler about her book Stuffed: A History of Good Food and Hard Times in Britain

It’s a common fantasy. You wake up and there is no one there. Civilisation, order, humanity have crumbled. You are alone. Yet, in some parts of the world, this is not a fantasy. Human civilisation has indeed gone.

What does this look like? What remains in a post-human landscape? And is this what awaits us?

In this week's episode, Nick Spencer speaks to Cal Flyn about her book Islands of Abandonment: Life in the Post-Human Landscape

For over 50 years now, Dan Dennett has written highly-praised, thoughtfully and provocatively on major philosophical issues.

His ideas about consciousness, evolution, freedom - and, of course, theism - have provoked wonder and anger.

In this week's episode, Nick Spencer speaks to Dan Dennett, about philosophy, Darwinism, naturalism and theism.

The age of boom and bust is over - we were told, shortly before the great crash of 2008-09. Such confidence is clearly ill-advised. Economies boom and economies bust - and there doesn't seem much we can do about it.

Or is there? How can you spot a crash coming? What should you do about it when it descends on us? And how can we respond so that, even if we can't banish them forever, we can limit their frequency and impact?

In this week's episode, Nick Spencer speaks to Linda Yueh about her book The Great Crashes: Lessons from Global Meltdowns and How to Prevent Them.

You have a mind, right? At least, that's what you and those who know you will think. But would you say the same of your pet? What about creatures like dolphins or octopus? Aliens (assuming they exist)? Robots and AI? God?

What does it mean to 'have a mind'? Are all minds the same? Why should such a costly thing appear in evolution? And if we understand our minds, does that mean we have finally understood ourselves?

In this week's episode, Nick Spencer speaks to science writer Philip Ball about his book The Book of Minds: Understanding Ourselves and Other Beings, From Animals to Aliens.

Everyone - even those who utter it with contempt - uses the word 'God'. But we don't all use it in the same way. Indeed, you could argue that we talk past each other more often when we talk about God than when we talk about any other topic.

So what do we mean when we talk about God? What does the word even mean? Is the God of the philosophers the same as the God of the religious? Or indeed the God of the atheists?

In this week's episode, Nick Spencer speaks to philosopher and theologian David Bentley Hart about his book 'The Experience of God: Being, Consciousness, Bliss'

Pentecostalism is the fastest growing religious movement in history, with nearly 600 million Pentecostals worldwide. How did the movement originate? What does it involve? And how will it change Christianity, society and politics in the 21st century?

Nick Spencer talks to journalist and author Elle Hardy about her book Beyond Belief: How Pentecostal Christianity Is Taking Over the World

We raise over a trillion every year in tax, and spent a hundred billion more than that. But where do we get it from? Where do we spend it? And is it used fairly, efficiently and wisely?

Nick Spencer talks to Director of the Institute for Fiscal Studies, Paul Johnson, about his book Follow the Money: How much does Britain cost?

We need to decarbonise, and fast. But 'going green' is not straightforward, not only practically but ethically. There is great potential there, but also huge risks. What are they? Who will win? And who might lose?

Nick Spencer talks to journalist and author Henry Sanderson about his book Voltrush: The Winners and Losers in the Race to Go Green

Journalism is bit like politics. As a rule, we say we don’t really trust either profession, and neither seems to be in particularly good health at the moment. But we definitely can’t live without them.

Nick Spencer talks to former editor of the Guardian, Alan Rusbridger, about his book Breaking News: the remaking of journalism and why it matters now
