  1. Introducing Rare Earth

    Tom Heap introduces Rare Earth, a programme exploring major stories about our environment.

  2. Steve Backshall Goes Off Grid

    Steve Backshall lives in a new build house which is very energy efficient and almost totally off-grid. However, achieving this has been extremely time consuming, expensive and pretty stressful. For this episode of Costing the Earth, Steve explores why -- when the cost of heating our homes is so...

  3. Save the Microbes!

    It's said that a teaspoon of soil contains more life than all of the humans on earth. Microscopic life that is - bacteria, fungi, protozoa, nematode worms and microarthropods like springtails and mites, but there's increasing evidence that this invisible world, the earth's microbiome, is under...

  4. Gardens of the Future

    Climate resilient gardens are a feature of this month's Chelsea Flower Show, but how can the experts help the typical British gardener prepare for the future? To find out, botanist James Wong asks whether the way we garden could protect us against the effects of climate change, and if we can...

  5. Investigation DRS

    Many of us can remember returning our pop bottles to the shop in return for cash and wonder why we can’t use a system like this today to reduce, reuse and recycle. In Scotland a Deposit Return Scheme has been on trial, but in a complex material world it’s not as simple as the schemes we might...

  6. Water pollution solutions

    Sewage is now discharged into our rivers and seas on a regular basis. It's joined by agricultural pollution and a host of microplastics. In this special debate programme, Tom Heap asks what's gone wrong with our water system. How did we get into this situation, what will it cost to put it right,...

  7. Losing Our History

    When castles collapse into the sea or ancient burial places succumb to floodwaters we lose a slice of our shared culture. Qasa Alom reports from the Norfolk coast on the threats to our heritage and asks if we all need to prepare for the emotional impact of climate change. Researchers from around...

  8. Costing the Earth - The Power of Nature Writing

    Costing the Earth - The Power of Nature Writing

  9. Energy Lessons

    After a winter of spiralling energy prices, Tom Heap asks whether our attitudes to energy consumption have changed. What lessons have we learned in the last twelve months, both as individual consumers and as a society - or are we putting our heads in the sand and carrying on as normal? Last week...

  10. The Sound of Nature

    Waves crashing on the shore, footsteps crunching on the forest floor. Stress levels plummet when we immerse ourselves in nature. Nick Luscombe meets the Japanese scientists working to bring the healing power of nature into the heart of the city. Nature's secret, they believe, isn't the sound you...

  11. Jobs for a Green Future

    UK commitments to phase out gas boilers and petrol cars may be good news for the environment, but do we have the skill to realise our ambitions? Where are all the trained workers able to fit heat pumps in our homes and electric car chargers along our roads? In this programme, Tom Heap joins...

  12. Greening the City

    New technologies are vital in the drive to turn our fossil fuel-based economies green and drastically slash carbon emissions. That technology requires investment and an enormous slice of the cash required is controlled by the financial markets of the City of London. Tom Heap meets the City's…

  13. Prawn Free

    Where do the prawns in your takeaway curry or pad thai come from? Peter Hadfield travels to South-East Asia to investigate the environmental impact of prawn farming. Producer: Alasdair Cross

  14. Surrendering to the Waves?

    As sea levels rise, tough decisions are going to have to be taken about the flood defences of coastal Britain. How realistic will it be to continue to maintain them in future? In this programme, Qasa Alom asks whether we are facing up to this yet, and visits two places where the effects are…

    more
  15. A Greener Government?

    Months of governmental chaos have seen contradictory policies on the environment come and go. Tom Heap asks where the Conservative Party now stands on the environment. Should we expect more onshore wind or a continuing ban, will farmers be paid to help wildlife? And what are the underlying trends...

  16. Community Energy

    Community energy might conjure up images of off-grid villagers working together to put up solar panels on a remote community hall. This is one model, but Tom Heap finds that there are now many more ways to join the clean energy revolution. From urban solar rooftop projects which train up young...

  17. How can I be a more sustainable parent?

    Since becoming pregnant, environmental historian and broadcaster Dr Eleanor Rosamund Barraclough has aspired to bring up her two children as sustainably as possible.

The Cetacean Strandings Investigation Programme in England and Wales, and the Scottish Marine Animal Strandings Scheme, have carried out thousands of autopsies....

  20. The Lost World of Ice

    The world's glaciers are melting at an unprecedented rate. 2022 has been a particularly disastrous year in the Swiss Alps, where new figures show that glaciers have lost 6% of their total volume of ice during this summer's heatwave. Three glacier-measuring stations have had to close this year, as...

  21. Saving Vietnam's Wildlife

    Life can be pretty tough for the pangolin. This scaly-skinned ant-eater is the most heavily trafficked mammal in the world.

  23. An Environmental Paw Print

    For many dog owners, watching your pet race around after a crow or leap joyfully into a stream is a source of great pleasure...but these natural behaviours all have an impact on the environment. Estimates of the UK dog population vary from 10 million all the way up to 13 million and the number…

    more
  24. The True Cost of Energy

    In the UK, more than half our electricity is generated without using fossil fuels. Despite that, the rocketing price of gas has lead to matching increases in our electricity bills. Why the disconnect? What could we be doing differently so that consumers benefit from cheap renewable power? And…

    more
  25. Wild Highway

    Running 12500km from the Arctic Circle to the borders of Greece, the European Greenbelt is one of the most ambitious conservation schemes ever devised. The idea was to use the no man's land of the Iron Curtain that divided Communist East from Capitalist West as a wildlife corridor to allow rare…

    more
  26. Future Tourists

    Nature and wildlife tourism has surged in recent years. Millions of us seem to want to want to follow in the footsteps of David Attenborough; meeting mountain gorillas, ticking off Africa’s big five mammals or hitting the waves to meet whales and dolphins. But is wildlife tourism good or bad for...

  27. Steve Backshall Listens to the Whales

    Steve Backshall explores whether slowing down and quietening noisy shipping could help protect Canada’s whale population.

  40. The Right to Swim

    On a hot summer's day the River Wharfe in Ilkley in West Yorkshire is a tempting place to swim. In 2020 it was designated as the first inland waterway to be safe for bathing. Just over a year later the water was found to be polluted by animal and human faeces and locals and tourists were advised…

    more
  41. Seeing the Wood for the Trees

    There have been big promises about tree-planting numbers over the last few years - but is there much point in planting more trees, if we're not looking after the ones we've already got? The Woodland Trust estimates that only 7% of the UK's native woodlands are in good ecological condition - with...

  42. All Aboard the Sir David Attenborough

    The public wanted to name her Boaty McBoatface, but in the end she got a slightly more stately name. The UK's newest polar research vessel, the RRS Sir David Attenborough, has just set out on her maiden voyage to Antarctica, where she'll enable scientists to research climate change and its…

    more
  43. Canoeing the Cam

    Britain's rivers are in crisis, with only 14% of them deemed to be in a good ecological state. Chalk streams are particularly vulnerable, as so much is taken out of them for use in our water supplies. Pollution from sewage and agricultural run-off only add to the problem. In this programme Tom…

  44. How green is my golf course?

    Golf courses do not have a good reputation when it comes to the environment. Keeping the greens and fairways looking immaculate usually means using pesticide, fungicide and fertiliser - as well as large amounts of water. Wildlife such as pecking birds and digging moles, which can damage the...

  45. My Toxic Cocktail

    We are all surrounded by synthetic chemicals in our everyday lives - from pesticide residues in food to chemicals used in the manufacture of household products - but most of us are not aware that they also make their way into our bodies. In this programme, environmental journalist Anna Turns...

  47. COP26: The Unheard Voices

    As world leaders gather in Glasgow you can be certain of one thing - the loudest voices won't be coming from the people most impacted by climate change. Inuit hunters on melting ice and Pacific islanders losing their homelands to rising sea levels won't be flying Business Class to Glasgow - they...

  48. Six Months on St Kilda

    Abandoned by its entire population in 1930, St Kilda has been uninhabited ever since. What's it like to spend six months with the birds on one of Britain's most isolated islands?
