It's 20 years since the first Harry Potter film was released and the movies and books have spawned a world of wizard-related retail opportunities. Elizabeth Hotson asks Chris Columbus, director of the first two Harry Potter films, how he dealt with the pressure of bringing the boy wizard to life. And we travel to Edinburgh for The Potter Trail tour which starts with a spell and ends in a graveyard. We step inside the magical Museum Context shop, and hear form owner, Andrew McRae. Plus, Scott Mendelson, a film critic and box office pundit at Forbes, tells us why he thinks the franchise has been so successful. And we end with a look at the most hallowed of magic artefacts, the philosopher's stone itself.

On this edition of Business Weekly, we’re looking at the rising cost of energy across Europe, and hear from Emma Pinchbeck of Energy UK on how producers and consumers are coping, plus Tom Wilson from The Financial Times analyses the causes behind the price hike. We hear about how some countries are scaling back their road building projects in the face of climate change and ask how best to get people out of their cars? Plus, we go to Ghana, where consumers are unhappy with a new tax the government wants to add to electronic money transfers made using mobile phones. And the BBC’s Michelle Fluerry is in the US state of Kentucky to meet people who have decided to quit their job, and reevaluate their lives during the pandemic.

What will be left of human civilisation in the geological record 100 million years hence?

Justin Rowlatt speaks to the geologist Jan Zalasiewicz of Leicester University in an extended interview, speculating on the durability of the human legacy. We may take pride in our cathedrals, technologies and feats of engineering. But what strange fragments will survive long enough for aliens visiting our planet in the distant future to discover? And will it be enough for those future geologists to figure out what caused the mass extinction we will leave behind in the fossil record?

This is an extended version of an interview recorded for Justin's Geochemical History of Life on Earth, also available on the BBC World Service.

The new variant poses a particular threat to China's hitherto successful zero-Covid strategy at a time when the country's economy is looking vulnerable.

Ed Butler gets the latest on the fast-moving Omicron variant from Boston University epidemiologist Eleanor Murray. One new development is a recent study in Hong Kong that found that one of the two main Chinese vaccines offers very little resistance against it. Health security expert Nicholas Thomas of Hong Kong's City University says the Chinese government is now in a race to deliver booster vaccines to its population, while stopping Omicron from leaching across its porous land borders.

It comes at a sensitive time, with the Beijing Winter Olympics to begin in February, and the government seeking to gently deflate a property market bubble ahead of a politically sensitive Communist Party Congress in October. But independent economist Andy Xie says that when push comes to shove, the government would rather lockdown the entire national economy rather than let Covid get out of control.

2021 has seen some extraordinary economic changes. First a global economic rebound, then a global supply chain crisis, then inflation of a kind not seen in western countries for decades. And finally millions of people deciding they didn't even want to go back to work after lockdown. So what could 2022 have in store? Ed Butler discusses all this with Oxford economist Linda Yueh of Oxford University and author of the Great Economists, and Mohamed El-Erian, President of Queens College Cambridge.

The World Bank says this could cost the global economy $17 trillion. Coronavirus brought education systems across the world to a halt. At its height more than ninety percent of the globally enrolled student body were not in school. That’s more than 1.6 billion learners. Nearly two years on from the start of the pandemic, hundreds of millions of children are still not back in the classroom. In Uganda, as the BBC’s Patience Atuhaire tells us, schools were closed in March 2020 before the country registered a single coronavirus case. They are yet to reopen. She interviews a father whose twelve children have missed nearly two years of school. Robert Jenkins, the Director of Education and Adolescent Development at UNICEF, says the global economic impact of this lost education amounts to $17 trillion. He says the need for governments around the world to reopen all schools is critical.

Roads? Where we’re going, do we need roads? Some countries think they've already got too many. In the face of a climate catastrophe, the Austrian and Welsh governments are reconsidering plans to expand their road networks, moving away from a car-first model to better include more environmentally modes of transport. In Wales, they’ve all but halted any new roads as Climate Minister Julie James tells us, and are instead looking at improving public transport and active travel measures. In Austria we speak to Leonore Gewessler, Minister for Climate Action in the national government, who says that to build more roads would only attract more traffic and therefore more pollution. Electric vehicles could go some way to lowering carbon emissions, but the take up isn’t fast enough, says transport researcher Giulio Mattioli and so reducing reliance on cars altogether has to be a priority. And that means reimagining how cities are built to accommodate convenience, but without the car – transport planner Susan Claris tells us how that can be done. Today’s programme is presented by Tamasin Ford and produced by Russell Newlove.

On this edition of Business Weekly, we’re looking at rising inflation in Turkey, and hear how different communities are trying to live during a period of economic uncertainty. Victoria Craig tours Istanbul to hear from shop workers and families caught up in the currency crisis. Plus we focus on the Netherlands, and Meta’s proposals to build a giant, energy-hungry data-centre there. We hear how the community is divided on the plans from Facebook’s parent company. We’ll look at the diplomatic spat between Lithuania and China, that now has implications for trade between the two countries and the wider European Union, and we also delve into the world of premium pet food, to hear how today’s cats and dogs are getting the luxury treatment from their owners. Business Weekly is presented by Sasha Twining and produced by Clare Williamson. (Image: Tourist shop in Istanbul's spice market, credit: Getty Images)

Why has it become so popular for millions of young people? Has the failure of conventional nest-eggs, rising student debt and high property prices forced twenty-somethings into an ever riskier outlook - and what's the pandemic got to do with it? Nachiket Tikekar, a 23 year old student of business, tells Ed Butler why he decided to stick all his spare money into stocks and shares and why he's not scared of the markets crashing. This has all been made possible by the rise of low-cost online trading platforms like The Zerodha, which is India's biggest. Somnath Mukherjee runs its business and legal operations. Ed also speaks to Sarah Pritchard, the executive director of markets at the UK's Financial Conduct Authority who are trying target these risk adverse investors with warnings through new platforms such as TikTok. And Lesley-Ann Morgan has led a global study looking at investment trends, including for younger people, across more than 20 countries for Schroders Wealth management. She says thousands of young people have been saving as a result of forced lockdowns, and are feeling more inclined to ignore traditional investment strategies. (Picture of a young investor.

What is at stake when a big company like Meta comes knocking on your door? The small Dutch town of Zeewolde is grappling with this. Meta - the parent company of Facebook, Instagram and WhatsApp - wants to build a huge data centre in the area which could be the biggest in Europe. It is a proposal which has raised questions about land-use, water consumption, political power and energy.

The municipality says it will bring significant benefits – but not everyone agrees. Opponents like local resident Sipke Veentra, say the centre will use five times the amount of energy that their local windmills provide. And local farmer Carla Dekker is concerned that prime agricultural land is being given over to development and is worried about the amount of water Meta will use. They both claim Meta is being given preferential treatment over local businesses. But those in favour, like Egge Jan de Jonge the local cabinet member who is steering the deal through, says Meta will have to provide new power supplies to feed the centre and that they have a proven record of having done this in the past.

Stijn Grove, from the Dutch Data Centre Association says there is no Dutch national strategy and that more political leadership is needed from the top. And Sebastian Moss, who watches the data centre industry for the website DatacenterDynamics says companies face similar challenges to Meta when trying to site hyper-scale data centres all over the world.

The pet food industry is a multi billion dollar business but are premium brands - with premium ingredients - worth spending more money on? And could insect protein be the key to a more sustainable way of feeding our animal companions?
