Start the Week - Climate activism: the next generation

Richard Powers’s prize-winning Overstory was an impassioned evocation of the natural world and a call to arms to save it. In his latest novel, Bewilderment, a father and son navigate a world seemingly bent on destruction. Powers tells Andrew Marr how the father, an astrobiologist, models planets in far away galaxies searching for life, while his nature-loving 9 year old struggles to understand why earth’s life forms are so thoughtlessly destroyed.

Mya-Rose Craig, aka ‘birdgirl’, is a young British-Bangladeshi ornithologist and activist. From a deep love of bird watching she has gone on to become a prominent environmentalist. In ‘We Have A Dream’ she speaks to 30 young indigenous people of colour to find out how their environments have been affected by climate change, and why young people are so involved in protecting the natural world.

The journalist Simon Mundy argues that climate change is affecting more than just the environment: everything from energy, farming, technology and business, as well as migration. In Race for Tomorrow, Mundy has travelled the world talking to the people at the front line of this transformation, from those battling to survive the worst impacts, to those eager to reap the financial rewards.

More or Less: Behind the Stats - Death, Tax and Dishwashers

New data appears to show that double vaxxed people between 40 and 79 are getting Covid at higher rates than people who are unvaccinated, but that's not the case. It's all down to how Public Health England estimates the size of different populations.

The Office for National Statistics described 2020 as "the deadliest year in a century". Now that we're more than two-thirds into 2021, we examine how this year is shaping up. We answer your questions on the new health and social care levy, and have words of congratulations and caution following Emma Raducanu's astonishing win in the US Open. Plus, where do you stand on in the dishwasher vs kitchen sink debate?

GUESTS: Mathematician James Ward Adele Groyer of the Covid-19 Actuaries Response Group Helen Miller of the Institute for Fiscal Studies.

Start the Week - Life in the first person

The neuroscientist Anil Seth is a leading researcher into consciousness. In his book, Being You, he explores why we experience life in the first person. He tells Tom Sutcliffe how our perceptual experiences are less a reflection of an objective external reality, and more a kind of controlled hallucination. He argues that perception is a brain-based ‘best guess’ – including our core sense of self – designed by evolution to keep the body alive.

Tiffany Watt Smith is interested in how the individual self can feel swept up and subsumed in crowds, and the tension between ‘feeling yourself’ and ‘losing yourself’. This has taken on added significance during a pandemic when collective experience has become tinged with anxiety. As Director of the Centre of the History of Emotions at Queen Mary University of London, she has also looked at how far being able to name an emotion makes it more real.

Emotional turmoil, from revenge to love, are writ large in Rigoletto – the season opener at the Royal Opera House in Covent Garden. It’s the first production by the company’s Director, Oliver Mears, and the first new show since the opera house closed because of Covid-19. Mears sees Verdi’s masterpiece as a modern morality play that pits power against innocence, in a pitiless world of decadence, corruption and decay.

More or Less: Behind the Stats - Vaccine waning, hot dogs and Afghanistan

Should we be worried that the protection against Covid-19 provided by the vaccines is going down? Could it really be the case that eating a hot dog takes 36 minutes from your life? The Bank of England holds 35% of Government debt. Who owns the other 65%? Has the UK spent more on Test and Trace than on its operations in Afghanistan?

More or Less: Behind the Stats - Covid, HGV driver shortages and protest costs

English Covid restrictions were lifted in July. Back then, some predicted that there could be as many as 6,000 hospital admissions a day by the following month. So, what happened?

The Metropolitan Police says it?s spent ?50 million on policing Extinction Rebellion since 2019. They?re on the streets again ? can it really be that costly?

The economics correspondent at The Economist Duncan Weldon puts government borrowing during the pandemic into context and talk about his new book, 200 Years of Muddling Through.

Are we running out of lorry drivers? And to what extent is Brexit to blame? We look at the numbers behind a claim that there is a shortfall of 100,000 lorry drivers in the UK.

Plus, disturbing evidence that Star Trek?s Mr Spock may actually be terrible at logic.

39 Ways to Save the Planet - New Nuclear

Nuclear power should be a powerful ally in the fight against climate change but cost and safety issues hold it back. Could a new generation be safer and cheaper? Tom Heap meets the team behind the molten salt reactor that can use nuclear waste as fuel and is claimed to be significantly cheaper and safer than current reactors.

Ian Scott was a senior scientist at Unilever, pioneering research into skin-ageing, but when he retired from the field of biological sciences he became fascinated by the costs of nuclear power. Why had nuclear electricity- which we'd once been promised would be 'too cheap to meter'- become one of the most expensive forms of energy generation. The answer lay with the safety mechanisms that have to be built-in to reduce the risk of another Chernobyl or Fukushima. If he could develop a system that would be much safer then it would, almost certainly, be much cheaper.

Scott's central idea- to use molten salt as a coolant rather than water- caught the eye of energy authorities in Canada and Ian's company, Moltex, has plans to build its first reactor in New Brunswick. Significant safety concerns remain, with some in Canada concerned about Moltex plans to use spent fuel from conventional reactors and others raising fundamental issues about the corrosive qualities of molten salt and the generation of radioactive tritium

Tom visits the Moltex laboratories and climate scientist, Tamsin Edwards, gauges the potential impact on greenhouse gas emissions.

39 Ways to Save the Planet - Black Gold

Biochar is an idea thousands of years old but one that seemed to have been (foolishly) lost by many along the way.

Like charcoal, biochar is made by baking wood in the absence of oxygen and then quenched. It can then be ground down and worked into the soil to improve fertility and crop yields. It's believed to have been applied thousands of years ago in the Amazon, to generate the Terra Preta.

The biochar locks in much of the carbon captured by the trees and stabilises it. Tom meets Forester Dave Faulkner and his team at Whittlewood to see the productions process in Northamptonshire.

Meanwhile, Josiah Hunt experimented with the process in Hawaii and now supplies across California. As well as capturing carbon and improving the soils, he says they're removing liability wood to reduce forest fires and are helping to produce green electricity.

Can this ancient process help bring new hope?

39 Ways to Save the Planet - Better Blocks

Concrete blocks are the foundations of the modern world but they could be greener. Tom Heap meets Colin Hills and his team turning waste dust and carbon dioxide into building materials.

Professor Hills of the University of Greenwich has developed a technique that mimics natural processes, using carbon dioxide as a glue to form stone aggregates from waste dust left behind by heavy industry. The spin-off company, Carbon 8 Systems, has compressed the process into a shipping container and now makes building materials in the UK and France with this clever carbon-munching technique. Colin's colleague, Nimisha Tripathi wants to adapt the system for the developing world, choosing waste from her native India- things like pistachio shells and banana skin- to make a tailored range of building products relevant to the region in which they're made.

Tamsin Edwards of King's College London joins Tom to consider just how much carbon dioxide we can remove from the atmosphere by developing this new generation of bricks and mortar. Producer: Alasdair Cross Series Researcher: Sarah Goodman
