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 the world’s most sensitive environments? The Covid-19 outbreak gave us a sudden, unexpected opportunity to answer that question. Some of the most magnetic natural places on the planet lost their...

Steve Backshall explores whether slowing down and quietening noisy shipping could help protect Canada’s whale population. A busy shipping lane between Vancouver Island and the Canadian mainland – known as the Inside Passage - is home to a community of Orcas. These are the unmistakable, sleek and distinctive, black and white members of the dolphin family otherwise known as Killer Whales. They’re smart and social and have a sophisticated language of clicks and whistles which helps them hunt...

It's said that the environment is the silent victim of war. In this programme, Tom Heap finds out how the conflict in Ukraine is affecting environmental work in the country. With so many people forced to flee, what happens to projects which were trying to protect fragile wildlife habitats? He talks to an award-winning Ukrainian environmentalist who has had to temporarily abandon his conservation project around Chernobyl in order to help with the humanitarian aid effort. Meanwhile, with...

Qasa Alom finds out if they can really deliver and just how sustainable and green these global sports events will be. Starting off with his home city of Birmingham Qasa discovers...

Making your finances work harder against climate change. Tom Heap speaks to Richard Curtis, British film director and architect of Comic Relief, about his Make My Money Matter campaign. This encourages everyone to find out where their pension money goes. He also speaks to the boss of a UK bank, Bevis Watts, and to the campaign director of switchit.green about how easy it is to move your bank account elsewhere. A special episode for anyone worried about what their money is - or isn't - doing...

Green industry is heading to Scandinavia's far north. Fossil fuel-free steel and clean, green wind energy are in great demand but what does this rapid development mean for the indigenous people of the region? Richard Orange reports from Sweden. Producer: Alasdair Cross

Millions of trees were brought down by this winter's storms. Storm Arwen in November proved particularly damaging, taking out whole swathes of woodland in Scotland and the north of England. It comes at a time when there is more focus than ever on planting trees, with the urgent need to both tackle climate change and produce more home-grown timber. At the moment, the UK imports more than 80% of the timber it uses. In this programme, Tom Heap visits two forest estates in the North East of...

The government announced its new energy strategy last week, outlining plans to tackle energy supply over the coming decades. In this edition of Costing the Earth, Tom Heap chairs a panel discussion which looks into the detail of the strategy, and asks what it will mean for both net zero targets and household bills. He is joined by a panel of experts: Roz Bulleid, Deputy Policy Director at the independent think tank Green Alliance; Chief Political Commentator at the i-newspaper, Paul Waugh;...

It's not easy fighting for nature in many of the former Soviet states. Antonia Bolingbroke-Kent reports from Tajikistan, on the trail of the snow leopard and the extraordinary people who protect them. This high corner of Central Asia is home to the world's biggest species of wild sheep and goats, prey of arguably the most beautiful of the big cats- the extravagantly furred snow leopard. After the fall of the Soviet Union a vicious civil war killed 100,000 people and saw many more displaced...

The pandemic has changed the way we work and shop meaning a growing number of offices and retail outlets are empty. So, what do we do with them? Knock them down and start again or find a sustainable way to reuse them? The buzz word is ‘retrofit’: redesigning and refurbishing an existing building. Elsie Owusu is an architect and, in this episode of Costing the Earth, she explores this current and contentious issue. It’s usually cheaper to build new, so what can be done to encourage developers...

In Northern Ireland peace and prosperity have long been prioritised over environmental protection. Tom Heap asks if a new generation can push nature and wildlife up the agenda. For decades a blind eye was often turned to suspect developments in natural areas and breaches of pollution regulations. A more recent upsurge in large-scale dairy, pig and poultry farming has added to the burden on Northern Ireland's once green and pleasant land. New laws to fight climate change and a new subsidy...

Energy prices have hit new heights. Gas and electricity bills will rocket for most people at the end of this month as the price cap is lifted and nobody filling their car could fail to notice record prices at the pumps. Energy too is at the heart of the biggest conflict in Europe for decades. Russia’s war machine is paid for with oil and gas and the West’s response is shaped by our reliance on that power source. What does all this mean for the environment? Can we maintain focus on carbon...

Landowners are being offered big money for land to absorb carbon dioxide emissions. What does it mean for British farming and the shape of the countryside? Tom Heap reports. Producer: Sarah Swadling

Perfluoroalkyl substances - or PFAS - are a group of thousands of man-made chemicals which have been widely used in everything from frying pans to firefighting foam. Anything which is non-stick, water-resistant or stain-repellent is likely to have been produced using PFAS. In the USA they have been linked to mass poisoning of water supplies, as the Hollywood film 'Dark Waters' documented. In this programme, Leana Hosea sets out to discover whether they are having an impact here. She teams up...

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 to stay out of the river. The River Wharfe certainly isn't unique, Britain's rivers are taking the brunt of rising populations, antiquated sewage treatment and intensive agriculture. Too much...

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 pests, diseases, climate change and development all threats to tree health. Meanwhile a report from Botanic Gardens Conservation International says that a third of the world's trees are at risk of...

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 impacts on the polar regions. Following a hundred years of polar exploration, this ship will write the next chapter in UK polar science. In this episode, ocean physicist Helen Czerski gets aboard to poke...

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 Heap takes a canoe trip along a waterway he knows well, the River Cam, to see for himself what's going on. He talks to environmental groups and local people, and asks whether the rapid expansion of...

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 pristine playing surfaces, are seen as a nuisance. But attitudes are starting to change in the golfing world. In this programme, Sybil Ruscoe finds out about efforts which are being made to make golf more...

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 investigates her own 'chemical body burden' - the amount of persistent, synthetic pollutants that have accumulated inside her system. A blood test shows her that traces of pesticides which were banned...

World leaders have offered up a suite of promises at the COP26 climate summit in Glasgow but how many of them will make a real dent in our greenhouse gas emissions? Tom Heap talks to experts in sustainable finance, methane emissions, deforestation, clean technology and energy to gauge the impact made so far. He's also joined by two veterans of many COP meetings, University of East Anglia climate scientist, Corinne Le Quéré and Bernice Lee of Chatham House. What do they make of the...

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 won't have the chance to fight for their rights amongst the world powers and corporate interests. Tom Heap brings those voices to the banks of the Clyde for the first of two special editions of...

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? Conor McKinney is a naturalist and broadcaster with what might be- depending on your personality- either the best job in the world or the worst. St Kilda is seriously isolated- it’s an archipelago of islands over one hundred miles west of the Scottish mainland and 40 miles of rough Atlantic waves away from the...
