Former mortuary technician Kristoffer Hughes wants to bring terramation - or human composting - to the UK. He believes it's a more natural and hopeful way for our bodies to be disposed of, and a more environmentally friendly alternative to burial and cremation.

Kristoffer tells Gabriel Gatehouse about the "epiphany" he had when he first witnessed the practice in the USA, his own experience of being 'buried alive' in a terramation facility, and what human compost can actually be used for.

The practice isn't legal in the UK yet - the Law Commission has suggested it could be explored as an option in England and Wales - but how much appeal would it really have, how much would it cost, and is it safe?

Neil Woods is a former undercover police officer who used to infiltrate drug gangs, but he now believes drugs should be legalised and the market regulated by government. He's a board member of the Law Enforcement Action Partnership (LEAP), which campaigns for drug policy reform around the world.

In the main episode Neil explained why he thinks prohibition of illicit drugs has failed and outlined his plan for the government to source and supply drugs like cannabis, cocaine and heroin through pharmacies or via sales in regulated shops.

In this special Q&A, Neil answers your questions on minimum ages for these drugs, the experiences of other countries, and the thorny moral question.

As an undercover police officer Neil Woods' job was to infiltrate drug gangs and put their leaders behind bars, but he says his work gradually convinced him that he was doing more harm than good. Since leaving the force he has become one of the UK's foremost campaigners for drug policy reform.

Neil tells this week's host, Jenny Kleeman, why he believes the war on drugs has failed, and sets out his alternative vision for legalising and regulating the use of cannabis, cocaine, heroin and other products. He thinks drugs on prescription or sold with age and dose restrictions, as well as health advice, would be the best way to keep users safe and wrest control of the market away from organised crime.

But, of course, Neil has his opponents. We ask whether the war on drugs really is failing, if legalisation would really eradicate crime and the black market, and whether legalisation might actually increase drug use and deaths.

Sarah Harper is Professor of Gerontology at the University of Oxford and one of the world's leading experts on demographic change. She challenges the widespread belief that ageing populations are primarily a social and economic burden, arguing instead that longer lives represent one of humanity's greatest achievements and an opportunity to rethink how society is organised.

In the last episode, Sarah explained why many of the pressures associated with ageing societies stem from institutions that were designed for a very different era. She argued that our welfare systems, labour markets and expectations around retirement no longer reflect the realities of modern life, where people are living longer, healthier lives than previous generations.

In this week's Q&A, Sarah joins James Marriott to answer your questions about the future of retirement, pensions and work in an ageing society. She explores generational resentment and how we can bridge the gap between old and young, whether inequality is more important than age, and whether politicians disproportionately focus on older voters.

This week, James Marriott talks to Sarah Harper, Professor of Gerontology at the University of Oxford and one of the world's leading experts on demographic change. She challenges the increasingly common narrative that ageing populations represent an inevitable economic and social burden, arguing instead that longer lives should be seen as an achievement that requires us to rethink the way society is organised.

Brendan Simms is Professor of the History of International Relations at the University of Cambridge and the author of The Return of the Great Powers. He challenges the widespread belief that Britain is in terminal decline, arguing that the UK remains one of the world’s four true Great Powers.

In this special Q&A, Brendan answers your questions on what steps Britain needs to take to stay relevant, whether its military is fit for purpose, and whether our soft power is overlooked.

Is Great Britain really still great? Is it in decline, or has the UK underestimated its own status in the world?

In his latest book The Return of the Great Powers, Brendan Simms, Professor of the History of International Relations at the University of Cambridge, challenges one of the most deeply rooted current assumptions in British public life and argues that the UK is still a significant player on the world stage.

While much of the national conversation focuses on economic stagnation, geopolitical uncertainty and the fading legacy of empire, Simms argues that the UK remains one of only four true Great Powers in the world today, alongside the United States, China and Russia.

Drawing on a framework of resources, reach, reputation and resilience, he joins Radical to make the case that Britain retains many of the characteristics that define global power: a strong economy, worldwide diplomatic influence, significant military capabilities and an overseas presence that allows it to project influence far beyond its shores.

Sophia Smith Galer hosts this week, and find out why Brendan Simms believes that great power politics has returned as the dominant force shaping international affairs. What does it mean to be a Great Power in the 21st century? Does Britain still belong at the top table? And how the growing rivalry between the US and China is reshaping the global order?

Derek Gow is a farmer, conservationist, author and leading rewilding advocate who has become one of the UK's most vocal champions of large-scale species reintroductions. In this special Q&A, he tackles some of your most challenging and provocative questions.

This week, John Burn-Murdoch speaks with Derek Gow, the British farmer, conservationist, author and rewilding pioneer who has become one of the UK's most outspoken advocates for large-scale species reintroductions.

From his farm in Devon, Derek breeds native British animals, including species that have been absent from the UK for centuries. His goal is to demonstrate what is possible when conservation ambition matches the scale of the ecological challenges we face.

A passionate supporter of reintroducing beavers across the country, Derek argues that restoring them into the wild can play a crucial role in tackling climate change, reducing flood risk, reviving wetlands and making landscapes more resilient to extreme weather.

His views have frequently brought him into conflict with parts of the farming establishment. Yet Derek insists that productive agriculture and ambitious rewilding are not mutually exclusive, and that with the right political leadership, the two can thrive side by side.

David Runciman, podcaster and former politics Professor, answers Your Radical Questions. In the main episode, David argued that lowering the voting age to six is a true expression of universal suffrage and could help reinvigorate our stagnant democracy. Now, our listeners challenge him on whether kids would just vote how their parents tell them,  and whether there’s any evidence or precedent to support his radical proposal. 

Plus, should knowledge and competence be rewarded in our democratic system? Should some votes count more than others and should our politicians have to pass tests before they stand for office?

Next week, our Radical guest is Derek Gow, a conservationist, rewilder and outspoken advocate of large-scale species re-introductions. He argues that we should give much more of our land back to nature and away from conventional farming, using the innate behaviour of native species – in particular beavers – to restore natural ecosystems which could help protect against the devastating effects of climate change. 

We want your radical questions for him, so please get in touch.
