Costing the Earth

Taking inspiration from President Kennedy’s Moonshot which united people around a goal to put man on the moon and spurred the development of new technology in the 1960s, the Earthshot Prize is centred around five simple but ambitious goals for our planet. Over the next three editions of Costing the Earth, Chhavi Sachdev meets the prize nominees from all around the world. This week Chhavi concentra...

Qasa Alom has always been told that his family farm in Sylhet, Bangladesh is his heritage. His parents have spent their time and money trying to maintain the estate and his father has always hoped Qasa would take on some of the strain. Born in Britain, Qasa had other ideas about how he wanted to spend his time but he now faces a new challenge; how to protect his family’s roots from climate change....

Naturalist and broadcaster Mike Dilger takes to the road to map the impact that global warming is having on Britain's plants and flowers. From the highest peaks of the Highlands to the lowest points of the East Anglian Brecklands our flowers are adapting to the changing seasons, but how many will survive and thrive into the future? Producer: Alasdair Cross

Adrian has a big idea. His home of Braunton, a village in North Devon, has a problem with flooding. Over the last decade he has seen it get worse. The village flooded badly in 2012 just after a million pound flood defence scheme was completed, and there was more flooding in 2016. Braunton has since had those defences upgraded, but more work is needed further up the valley. Instead of more expensiv...

Government action on climate change is sluggish. Could rich individuals cut through red tape and fund measures to cool the planet from their own pockets? And should they be allowed? Presenter/producer: Jolyon Jenkins

How will Britain's power system need to change for a zero carbon world? Tom Heap investigates. Producer: Alasdair Cross

Australia's government is famous for its lack of interest in climate change. Despite increasing problems from bushfires and droughts, Prime Minister Scott Morrison and his Liberal-led coalition government continue to promote coal-mining and dodge efforts to reduce the country's carbon emissions. It's all the more extraordinary then that one Australian state, governed by Mr Morrison's party is stre...

When a cargo ship blocked the Suez canal for nearly a week, the eyes of the media focussed on shipping. Hundreds of vessels were stuck as tailbacks built up at the entrance to what is one of the world's busiest trade routes. What effect does the sheer quantity of goods which we routinely move around the globe have on the environment? Are there ways of 'greening' shipping and lessening its environm...

The UK has dramatically reduced the amount of waste which goes into landfill over the last 25 years, but there are are still decades worth of rubbish underground, buried by generations gone by. Until the 1970s there were almost no rules about what could be put into landfill and very few records were kept before the 1980s, so no-one really knows what's lurking underground. The 1990s saw a change of...

How well protected is Britain's coast and its wildlife after Brexit? Chef and fisheries campaigner, Hugh Fearnley-Whittingstall joins Peter Gibbs to examine the health of our seas. Can our network of Marine Protected Areas be strengthened and expanded? What impact is climate change having on our waters? How can we lift the curse of plastic pollution from our beaches? Surfers, fishermen, campaigner...

The powerful gene editing technique CRISPR that allows us to rewrite DNA may soon provide a tool to help save our planet’s biodiversity. CRISPR has been described as ‘molecular scissors’ and is used to make targeted, precise changes to the DNA of plants and animals, with all the ethical questions it raises. Since it was developed by scientists 9 nine years ago, research into uses of CRISPR has bee...

Realising your pet cat has brought home a 'gift' or perhaps a snack they plan to eat in front of you is never pleasant. Many owners will scramble to intercept and release the poor prey but that may be too little, too late. Cats have been blamed for an estimated 100million wildlife kills in the UK each Spring and Summer but it's hard to know what really goes on when they're out on the prowl at nigh...

Dame Glenys Stacey is charged with the job of keeping the government on track toward a greener future. She talks to Tom Heap in her first interview as the head of the new Office for Environmental Protection. If public bodies in England such as the Environment Agency, Natural England and local authorities fail to keep rivers clean and city air breathable then it will be Glenys Stacey who will try t...

Dr Seuss' fable of needless consumerism and environmental ruin, The Lorax, is half a century old this year. The 'shortish, brownish, oldish and mossy' character who 'speaks for the trees' increasingly features on placards at demos. Michael Rosen looks at the book's influence on the modern environmental movement and charts its journey from ignored to censored, embraced by the mainstream and inevita...

How has one year of lockdown changed our environment in the UK and around the world? Tom Heap is joined by air quality expert, Ally Lewis, psychologist Lorraine Whitmarsh and the BBC's South Korea correspondent, Laura Bicker to find out how we- and the natural world- have been changed by the pandemic. Producer: Maggie Latham

The COP26 conference in Glasgow in November is going to be a very important moment in tackling climate change. We are currently not on track to meet the goal of limiting global temperature rise to between 1.5 and 2 degrees above pre-industrial levels. According to the UN Intergovernmental Panel on Climate Change, we need to halve total emissions by the end of 2030 if we’re to be on track to hit th...

In September at the UN General Assembly China announced that it will aim for carbon neutrality by 2060. Celia Hatton and guests discuss how China might meet this target, and what this means for the world. With Barbara Finamore, Senior Strategic Director at the Natural Resources Defense Council, Sha Yu, Co-Director of the China Program at the Centre of Global Sustainability at the University of Mar...

As some places in the world become too hot for humans to live, Tom Heap explores the cost to the environment of air conditioning. Air conditioning is one of the fastest growing sources of energy consumption, but it's already placing enormous strains on power grids, while also contributing to climate change. Across the world, building codes are making it virtually impossible to build new offices wi...

As our planet continues to warm, and climate issues move rapidly up the political agenda, the environmental movement itself is also changing shape. In the second of a two-part series looking at the past, present and future of the environmental movement, Journalist and Black and Green Ambassador Jasmine Ketibuah-Foley looks to the future. Speaking to academics, futurologists, and the activists and...

It's fifty years since the first blossoming of environmental campaign groups. Friends of the Earth, Greenpeace and the organisation which was eventually to become the Green Party were all set up in the early 1970s - all within just a few years of each other. In part 1 of this two-part series, Tom Heap takes a look back over the last half century of environmental protest. He talks to some of the bi...

Last year wildfires in the Amazon made headlines news. This year we've hardly heard about them - but that doesn't mean they're not happening. In fact the number of rainforest fires in Brazil rose by almost 20% in June, reaching a 13 year high, according to government data. Some estimates now point to 2020 being an even worse year for forest destruction than 2019. Meanwhile, from California to Sibe...

Record-breaking temperatures and months of severe drought fuelled a series of massive bushfires across Australia last winter. Dozens of people died and millions of hectares of bushland and forest were burnt. Australia's plant and animal life are well adapted to natural fire but the additional burden of climate change ensured that many of the fires were more intense and widespread than ever before....

Do you know how much water you use? Despite campaigns to reduce our personal water usage from around 143 litres each per day to closer to 100, it's not improving. Meanwhile Tom Heap has discovered that an innovation to a product we use every day, an innovation which promised to save water is actually making things worse. Billions of litres are being wasted every week – enough to supply the cities...

Ellen Husain investigates the presence of pathoghens in the marine environment. She learns how surfers and regular sea swimmers may be more likely to have anti-microbial resistant bacteria in their bodies, and finds out about the ways in which antibiotics find their way into our oceans. Is the way we manage our seas actually fuelling the rise of antibiotic resistant bacteria and increasing the ris...

With an ever greater demand for more housing, and Boris Johnson calling for the country to "build buld bulid" post lockdown, Peter Gibbs looks at current trends in house-building. Are the government's plans for "garden communities" as environmentally-friendly as they sound? And how could developers be encouraged to build in a way which incorporates nature rather than squeezing it out? Produced for...
