It was known as the Great Smog. In 1952, London was blanketed for five days in a thick toxic layer of soot and sulphur dioxide, leading to thousands of premature deaths. The outcome was the Clean Air Act of 1956. In this programme, Helen Czerski and Tom Heap ask what's changed in the seventy years which have passed since then. How clean is the air we now breathe?

Notes de l’épisode
The shadowy world of wildlife crime is estimated to be one of the four biggest illegal trades in the world. It runs the gamut from the international smuggling of ivory and exotic pets to hare coursing and badger baiting. The impacts of wildlife crime vary - in some cases it means a threat to endangered species, in others it takes the form of cruelty to individual animals. Could the unregulated world of social media make it easier than ever for wildlife criminals to evade the authorities? Or will advances in tech - including exciting forensic breakthroughs - be enough to stop them in their tracks?
With panellists:
- Fiona Howie, wildlife veterinary pathologist at Scotland's Rural College - Neil D’Cruze, UK Director of international animal welfare organisation Four Paws - Christian Plowman, Program Manager - Wildlife Cybercrime at the International Fund for Animal Welfare

Who's the hero that will protect us from the impact of extreme heat, rain and whatever else climate change might throw at us in future? Forget someone in a cape, maybe it's the person quietly sketching buildings on a bit of paper.
Architects shape the buildings we live in and rely on - can they change the way they work to make sure that our homes are smart enough to outpace the challenges of climate change? And can they lead the way in cleaning up the impact of the building industry? Or is the challenge just too great?
We find out with the help of:
- Isabel Allen, editor of Architecture Today - Barnabas Calder, reader in architecture at the University of Liverpool - Jay Morton, director of Bell Phillips Architects and incoming President Elect of RIBA

Beneath our feet is a world wide web that keeps us all alive. Estimated to be the origin of about 97% of the calories we eat, soil is fundamental to life. But it's a whole living world of its own. A biological engine, a carbon sink, and home to an abundance of bacteria, insects and worms. Tom Heap and Helen Czerski find out how soil is made, how it's faring in a world of intensive farming and how to get it back to full health.
Joining Tom and Helen to dig into the hidden drama of soil are:
Jack Hannam, Professor of Sustainable Agriculture & Biodiversity at the University of Greenwich’s Natural Resources Institute Duncan Farrington MBE, farmer and founder of Farrington Oils Simon Jeffery, Professor of Soil Ecology at Harper Adams University Dr Rachel Cassidy, lead scientist on Northern Ireland's Soil Nutrient Health Scheme.

The 2026 World Cup is expected to be the most environmentally costly yet. But are there alternative models that provide sporting thrills without the carbon cost?
Helen Czerski and Qasa Alom consider the climate impact of the biggest events and the impact of climate on sport at every level. Whether you're a hugely rich footballer sweltering in a World Cup final or a kid who can't play on a waterlogged pitch, the problem- and perhaps the solution - are the same.
Qasa and Helen are joined by Norwegian international footballer Morten Thorsby and Claire Poole of Sports Positive to discuss the upcoming World Cup in the US, Canada and Mexico. Professor of Global History at Oxford University and batsmen for the Croatian national cricket team, Peter Frankopan and Indian cricketer and commentator Abhishek Jhunjhuwn consider the impact of a warming climate on players, professional and amateur, who play their sport in the full glare of the sun for up to eight hours.

Notes de l’épisode
Plunge into the chilly embrace of the UK's lakes and you enter troubled waters. They're a place for recreation and an inspiration for our greatest poets but they're also on the frontline in the battle against pollution. The biggest lake in the British Isles, Lough Neagh, is plagued with toxic green algae that sucks the life out of its waters, but nobody seems able to stop the relentless flow of agricultural, industrial and domestic pollution that feed it. Meanwhile, Lake Windermere, birthplace of the Romantic movement, is suffering from a record number of illegal sewage spills that make wildwater swimming a dicey business.
Tom Heap and Helen Czerski paddle through the history and legends of our lakes and lochs, search for solutions to their present day problems and celebrate the natural life that still flocks to these beautiful places.

This year London Zoological Society marks its 200th anniversary. Established in 1826, today it has around 8000 animals and claims to be "the original scientific zoo". In this programme, Helen Czerski and Tom Heap look back at the role of zoos across the centuries and ask where their future lies. From public entertainment to conservation projects, do they have a part to play in an age when technology means we can see animals virtually, up-close and in high-definition, without having to keep them in captivity? Tom and Helen visit the former site of Bristol zoo in Clifton, now awaiting development, and are joined in the studio by a panel of experts to discuss the history, future and philosophy of the zoo.

150 years ago the British research ship Challenger returned from a three and a half year voyage that changed the world. Plucking species from every ocean, at depths never explored before, the Challenger kick-started the science of oceanography and paved the way for a world connected by undersea communication cables.
To celebrate the Challenger's legacy, Helen Czerski and Tom Heap are at the world's biggest ocean science conference in Glasgow to ask what the next 150 years may hold. Is the age of the human explorer over, replaced by robots and DNA sampling, or is there still a space for wonder as we explore the depths of our planet's oceans?
With Tom and Helen at the AGU Ocean Sciences Meeting are three top ocean explorers- Kirsty McQuaid from Nelson Mandela University in South Africa, Murray Roberts of Edinburgh University and Sofie Spatharis of Glasgow University.

What does the arrival of winter mean for plants and animals? In this programme Tom Heap and Helen Czerski find out how wildlife survives the freezing temperatures and short days of the winter months. In a time of climate change, they also ask how warmer weather patterns are affecting the natural world at this time of year. Do we have to get used to the idea of winters without snow and ice, and will winter scenes of robins on snowy branches and children sledging down hillsides only exist on Christmas cards?

Notes de l’épisode
How we get around town has never been more political, with controversies over low traffic neighbourhoods and 15 minute cities, and rows about congestion charging and public transport breaking out all over the country. Tom and Helen are in search of the kind of consensus that makes things faster, cheaper and smoother for all of us. What works and what’s been a complete flop? Should we all stop moaning and get on our bikes? Who is the reshaping of traffic flows working - and not working - for? And could Milton Keynes have all the answers?

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?
