Whether you love to express yourself through fashion, or find getting dressed a chore, clothing isn’t optional - and every choice has an impact. So how do our fashion choices affect the environment? Who's paying the price? And - most importantly - how can we do things differently? Can individuals and business rethink how we see clothes to prioritise the planet? Tom Heap and Helen Czerski get beneath the surface on this huge subject with Patrick Grant, presenter of The Great British Sewing Bee, hugely influential professor and author Kate Fletcher, and Simon Platts, a sustainability consultant with decades of industry experience. After you listen to this you might never see your clothes the same way again. Featuring: Patrick Grant - Presenter and entrepreneur Kate Fletcher - Professor of Sustainability, Design and Fashion Systems in the Manchester School of Art at Manchester Metropolitan University Simon Platts – Sustainability consultant Skye Pennant Julian Ellis-Brown & Finlay DuncanPresented by Tom Heap & Helen Czerski Produced by Beth Sagar-Fenton & Toby Field Mixed by Ilse Lademann Editor: Alasdair Cross

For thirty years world leaders have been gathering to negotiate the planet's route away from climate disaster. For thirty years carbon emissions have been rising and hopes have been fading. Is it time to admit defeat and search for a new strategy to persuade corporations and individuals to cut their pollution and save the planet?As the COP30 summit begins in Brazil, Helen Czerski and Tom Heap will be joined by an expert panel eager to come up with fresh solutions that could accelerate climate action and bring a unified, international response to the existential crisis of our time.With them are Nigel Topping, Chair of the UK Climate Change Committee, Corinne Le Quéré, professor of climate change science at the University of East Anglia, Anna Åberg from the Chatham House think tank and Georgina Rannard, BBC Climate and Science correspondent.Producer: Alasdair CrossAssistant Producer: Toby FieldRare Earth is produced in association with the Open University

It's 200 years since the first passenger rail journey saw George Stephenson’s Locomotion No.1 travel 26 miles between Shildon, Darlington and Stockton. Environmentalists love trains - making a journey by rail can be up to 80% greener than doing it by car - and there are exciting new inventions hoping to make train travel even greener. But can we pin part of the blame for global warming on the invention of the railways in the first place?

Efforts to reduce our carbon emissions are falling far short of what’s necessary to keep our temperature rise below 2 degrees centigrade. Is it time to seriously consider another option- using technology to cool the planet? Tom Heap and Helen Czerski explore the controversial field of geoengineering.They're joined by Shaun Fitzgerald, Director of the Centre for Climate Repair at Cambridge University, Peter Brannen, author of The Story of CO2 is the Story of Everything and by Alex Davey, Deputy Director of Science at the Royal Botanic Gardens Edinburgh.Producer: Alasdair CrossAssistant Producer: Toby FieldRare Earth is produced in association with the Open University

Can the insurance industry save the planet? With the nod from insurance companies a must for everything from coal mines to new homes, is the industry ready and willing to wield its power? When huge swathes of Los Angeles were destroyed by wildfire in 2025 the spotlight shone on the insurance industry. Would insurers pay out billions of dollars to rebuild in exactly the same way, in exactly the same place, in a region in which the risk of wildfire is only going to increase?Tom Heap and Helen Czerski take a deep dive into the role of the insurance industry in the climate crisis. Why can new homes in floodplains be insured? Are the rest of us subsidising risky behaviour with our own premiums? And are those in the industry trying to take revolutionary steps to prevent further climate damage? Contributors include: - Dr Lisa Dale, Senior Lecturer at Columbia University’s Climate School - Dr Franziska Arnold-Dwyer, Associate Professor of Law at UCL and author of 'Insurance, Climate Change and the Law’ - Lee Harris, insurance correspondent at the Financial Times - Lindsay Keenan, environmental campaignerProducer: Beth Sagar-FentonRare Earth is produced in collaboration with the Open University

80 years since the dropping of the first atomic bomb on Hiroshima, Tom Heap and Helen Czerski ask how our relationship with nuclear power has evolved.At 8.15 on the morning of the 6th of August 1945 a new era began for this planet. For the first time humankind had the power not just to exploit or damage nature, but to destroy it utterly.Tom and Helen are joined by Mark Lynas, author of Six Minutes to Winter: Nuclear War and How to Avoid It and by Professor Timothy Mousseau of the University of South Carolina, a biologist who has studied the environmental impact of the nuclear disasters at Chernobyl and Fukushima. Also in the studio is Dr Fiona Rayment, President of the Nuclear Institute.Producer: Alasdair CrossAssistant Producer: Toby FieldSpecial thanks to Archie McWatt of the University of the West of EnglandRare Earth is produced in association with the Open University

A ban on commercial hunting for whales came into force 40 years ago. Tom Heap and Helen Czerski look back on the whaling industry with one of the last of Shetland's whalers and ask if our largest mammals have bounced back from the extinction that so many species were close to reaching.They're joined by Jayne Pierce of the South Georgia Heritage Trust, the marine biologist and author of Eat, Poop, Die, Joe Roman and by linguist Inbal Arnon. Joe talks about his latest study for Whale and Dolphin Conservation which reveals the importance of whales in moving nutrients around the ocean while Inbal talks about her work comparing how whales and human babies learn to communicate. Jayne discusses this weekend's festival in Dundee which commemorates Scotland's role in the whaling industry and marks the launch of the Whaler's Memory Bank, a project to capture the voices of the last of the men who spent the British winter in the Antarctic capturing and processing the whales that found their way into our margarines and military hardware until the 1960s.

The transition to an economy based on renewable energy and electric cars needs huge quantities of materials like copper and rare earth metals. Sourcing them can be a problem. Mining damages the surrounding landscape and many of the materials come from unstable regions with poor records on child labour and environmental regulation. Are there alternative materials or do we simply need to consume less? Tom Heap and Helen Czerski investigate.Producer: Emma CampbellRare Earth is produced in collaboration with the Open University

Datacentres are big business, and vast numbers of them are being built around the world. In the UK, Amazon has announced plans to invest £8bn over the next five years building new datacentres, £3bn has been spent in the UK by Amazon’s cloud computing business since 2020 and Google is spending millions on a new centre in Hertfordshire. All this data handling is necessary because we're storing more of it and making more complex AI internet searches. The energy cost of this shift is so huge that the big tech companies are commissioning their own nuclear power stations. Each data centre requires energy to run and vast quantities of water to cool it. Both have significant environmental costs, particularly in the hottest and driest regions. Google's greenhouse gas emissions have increased by nearly 50% in the past five years, largely due to the energy demands of Artificial Intelligence.Tom Heap and Helen Czerski ask if we really need to handle all this data. Are there more efficient ways for us to store and search or should we be coming up with more efficient data centres which exploit renewable energy resources and cool themselves naturally with seawater or Arctic ice?To answer these big questions for our internet future they're joined by Tom Jackson, Professor of Information and Knowledge Management at Loughborough University Business School, Aurora Gomez Delgado from the campaign group Tu Nube Seca Mi Río (Your Cloud is Drying My River) and Mark Bjornsgaard from the data centre company, Deep Green.Producer: Alasdair CrossRare Earth is produced in association with the Open University

In 2019 the UK made a commitment to reach net zero carbon emissions by 2050. Since then the political consensus has broken down and analysts doubt that current government policy has any chance of reaching the net zero goal. Tom Heap, Helen Czerski and an expert panel stress-test net zero. Is it still achievable? Is it even politically possible in a world of trade wars, Trump's anti-environment agenda and the rise of Reform?Producer: Emma CampbellRare Earth is produced in association with the Open University

Insects are the quiet engineers of the environment - pollinating our plants, balancing our ecosystems and clearing up our waste. Some insects can digest plastic, and they play a vital role in crop production. At the same time their populations are under threat from pesticides, habitat loss and climate change. In this programme, Helen Czerski and Tom Heap explore the largely ignored world of insects. Could they be the answer to some of the environmental problems we have created? Would eating them help lower our carbon footprint, and will the western world ever overcome its squeamishness to the idea? Helen and Tom explore the weird and wonderful world of insects with a panel of experts.Producer: Emma CampbellAssistant Producer: Toby FieldRare Earth is produced in association with the Open University

From ancient Rome onwards our civilisation has been built on concrete. It's incredibly useful but emits huge quantities of carbon dioxide in its production. What are the alternatives? Tom Heap and Helen Czerski explore the issues with a panel of experts: Professor Colin Hills from Greenwich University, Smith Mordak Chief Executive of UK Green Building Council, and structural engineer Roma Agrawal, who worked on the construction of London's tallest building, the Shard.Producer: Emma CampbellAssistant Producer: Toby FieldResearcher: Harrison JonesRare Earth is produced in association with the Open University

The islands of the Pacific Ocean are on the frontline of climate change. Sea level rise will eventually erase some from the map and make many more uninhabitable. Tom Heap and Helen Czerski hear from the people of the region and explore its stunning wildlife both above and below the waves.With them in the studio are Professor Tammy Horton from the National Oceanography Centre in Southampton and BBC One Show naturalist, Mike Dilger. Tammy studies- and names- some of the thousands of creatures recently discovered living at depths of 4-6km in the Pacific's Clarion Clipperton Zone, while Mike has just returned from the bird-watching trip of a lifetime, spotting the extraordinary Birds of Paradise of Papua New Guinea.Samoan climate journalist Lagipoiva Cherelle Jackson joins in the conversation to consider how Pacific islanders respond to the prevailing narratives around climate change. She says that the islanders have no wish to be presented as victims and are well placed to stand up for their rights in international climate negotiations and to actively lead efforts to maintain their rich cultures, despite the rising tides.Producer: Alasdair CrossAssistant Producer: Toby FieldResearcher: Harrison JonesRare Earth is produced in association with the Open University

The shipping industry is an enormous source of pollution. Ships burn dirty fuel oil that helps contribute to the industry's global carbon emissions and even in port they continue to belch out noxious fumes that pollute the air of many of our major port cities. Tom Heap and Helen Czerski search for the solutions, from a return to sailing ships to new fuels - and even the possibility of ships being more like penguins - with a panel including:Paddy Rodgers, Director (Chief Executive) of Royal Museums Greenwich and former CEO of EuronavTristan Smith, Professor of Energy and Transport, Bartlett School of Environment, Energy & Resources (UCL) Aoife O’Leary, CEO of Opportunity GreenProducer: Beth Sagar-FentonAssistant Producers: Toby Field and Harrison JonesRare Earth is produced in association with the Open University

PFAS chemicals are all around us. They're used in frying pans, food packaging and waterproof coats but they have been linked to thyroid disease, liver damage and cancer. The trouble is that PFAS just doesn't go away- these 'forever chemicals' build up in our bodies and the environment.Tom Heap and Helen Czerski look back at the invention of these miracle chemicals, their use in the Second World War and the Space Race and meet Robert Bilott, the American lawyer who held the PFAS manufacturers to account, going head to head with the enormous DuPont corporation. They're also joined by Stephanie Metzger of the Royal Society of Chemistry, Hannah Evans from the environmental charity Fidra and by the journalist Leana Hosea of Watershed Investigations.Producer: Alasdair CrossAssistant Producer: Toby FieldRare Earth is produced in association with the Open University

40 years ago a hole was discovered in the ozone layer. It provoked an international effort to ban the chemicals that were destroying our protection from the sun. Tom Heap and Helen Czerski are joined by Jonathan Shanklin, one of the team that realised that CFC chemicals used in aerosol cans and refrigerants were helping to create a 20 million square kilometre hole in the ozone layer above Antarctica. Also on the panel they speak to Alice Bell, author of ‘Our Biggest Experiment: a history of the climate crisis’ and head of policy, climate and health at Wellcome, and Bristol University's Professor Matt Rigby who helps monitor how well countries are sticking to their promises on protecting the ozone layer.They discuss the unparalleled international unity that swiftly banned the worst of the ozone-destroying chemicals, and ask why we can't come up with a similar solution for manmade climate change. Tom will be meeting the detectives dedicated to hunting down the chemicals that still threaten the ozone layer and come with an enormous cost to the climate.Featuring contributions from:Jonathan Shanklin - Emeritus Fellow, British Antarctic SurveyMatthew Rigby - Professor of Atmospheric Chemistry, University of BristolAlice Bell - Head of Policy: Climate and Health, WellcomeProducer: Beth Sagar-Fenton Assistant Producer: Toby FieldRare Earth is produced in collaboration with the Open University

The wolf has mounted an extraordinary comeback. Once hunted to extinction across Western Europe, the wolf has taken advantage of the collapse of the Iron Curtain and the depopulation of the countryside to spread from east to west, reaching the suburbs of Amsterdam and Brussels. Only Britain, Ireland, Malta, Cyprus and Iceland now lack the top predator that haunts our fairytales.Tom Heap and Helen Czerski go face to snout with the wolf to find out the secrets of its success. They're joined by writer, Adam Weymouth, who tracked the route of a pioneering wolf called Slavc that made its way from Slovenia to Verona, kick-starting the return of the wolf packs to swathes of northern Italy. Erica Fudge of Strathclyde University shares her research into werewolf tales of the early modern period and BBC Central Europe correspondent Nick Thorpe digs into the relationship between farmers and wolves in their Carpathian heartland to reveal the conflicts we can expect as the western wolves increase their population.
