Will online shopping and AI combine to kill the high street clothing store?

Ed Butler gets himself digitally measured up in order to try on outfits in cyberspace, with the help of Tom Adeyoola, founder of virtual browsing business Metail. Meanwhile Julia Boesch - who runs Outfittery, one of Europe's biggest online fashion retailers, out of her office in Berlin - explains how artificial intelligence is enabling her company to provide customers with the kind of individualised style advice they would normally find in a bespoke tailors.

So is the roll-out of AI-enhanced phone-based services going to revolutionise the way we buy our attire? Yes, says Achim Berg of consultants McKinsey - but not quite yet.

At what point should you give up your day-job to pursue your own business side-project full-time? And should governments do more to help those who want to do it?

Manuela Saragosa explores the world of the successful "side-hustler" - the closet entrepreneur who takes an after-hours pet project and turns it into a whole new business. Alexandria Wombwell-Povey gave up insurance brokerage to launch her jam-making company Cham, while Emma Jones set up the website Enterprise Nation to support such go-getters.

Meanwhile, Maddy Savage reports from Sweden, where all full-time employees have a legal right to unpaid leave in order to pursue their own start-up.

If the UK crashes out of the EU on 29 March with no agreement on continuing trade relations, how will it affect Britain's supplies of fresh food? Could the country's supermarket shelves be left empty?

Dan Saladino speaks to farmers, traders and officials fretting at the unknown but potentially serious consequences of a "no deal" Brexit for food security in the UK, as well as one middle class family who are already stockpiling their own food supplies.

Interviewees include Guy Singh-Watson of Riverford Farm, Professor Tim Lang of City University London, Ian Wright of the Food & Drink Federation, Andrew Opie of the British Retail Consortium, Emily Norton of Nuffield College Oxford, Tim Worstall of the Adam Smith Institute, and New Covent Garden mushroom trader Michael Hyams.

Climate Change: Can the world economy continue to grow without burning fossil fuels? Or do we all need to cut back on our consumption in order to save the planet?

It is a question that splits the green movement. Justin Rowlatt hosts a fiery debate between two environmentalists on either side of the divide, who have already been tearing chunks out of each other in a very public dispute online.

Michael Liebreich, who runs a clean energy and transportation consultancy in London, says the technological solutions to global warming are within our grasp, and that maintaining economic growth is essential to bringing carbon emissions under control. Meanwhile Tim Jackson, professor of sustainable development at Surrey University, says that it is precisely the world's obsession with economic growth that is dooming Planet Earth to disaster.

Are Apple and Samsung running out of people to sell their smartphones to? And who wants to pay for an upgrade when their old phone is good enough?

Manuela Saragosa asks whether Apple's recent disappointing earnings are less to do with China's slowing economy - as the company claims - and more the fact that the market for iPhones has become saturated. With few major tech improvements on the horizon, is the smartphone about to become just another mass-produced, low-margin product?

The programme features interviews with phone industry analyst Ben Wood of CCS Insight, management professor Yves Doz of Insead in Paris, and Barry C Lynn of the Open Markets Institute thank tank in Washington DC.

More and more women are choosing to freeze their eggs in their twenties - but is it all just a big waste of money?

Manuela Saragosa speaks to Jennifer Lannon, who paid thousands of dollars at the age of 26 to preserve her eggs as a hedge against infertility later in life. But are the companies that offer this service - sometimes at special cocktail parties - just exploiting women's anxieties?

Patrizio Pasquale is Professor of Obstetrics, Gynecology, and Reproductive Sciences at Yale is a sceptic. But Gina Bartasi, founder of the US fertility business Kindbody, says it's all about female empowerment and overcoming the patriarchy.

Drones have been used increasingly in Africa for survey and mapping, but will cargo drone delivery companies be the next big thing? Jane Wakefield visits Mwanza on the banks of Lake Victoria to speak to African and international companies hoping to cash in on the drone delivery market.

Presented by Ed Butler.

The mega-philanthropist is in Davos lobbying governments and the global business elite to donate money towards the fight against infectious diseases. But is the world's second richest man the best person to spearhead this effort?

Ed Butler speaks to Mr Gates about why he considers it critical that the US and other rich world governments continue to finance efforts to fight Aids, malaria, polio, TB and the like. Meanwhile, Peter Sands - executive director of the Global Fund, one of the four major health initiatives that Gates is backing - explains why any let-up in the fight could be very costly indeed, particularly for the developing world.

But the philanthro-capitalism embodied by the Bill & Melinda Gates Foundation faces increasing criticism. Sophie Harman, professor of politics at Queen Mary University of London, expresses her qualms about their lack of accountability, while historian Benjamin Soskis of the Urban Institute in the US says the very willingness of Gates to lobby for good causes is raising questions about why wealthy individuals should wield such influence over public policy.

Dating apps like Tinder are a multi-billion dollar business, but have they reduced romance to a commodity? Vivienne Nunis speaks to Stanford University economist Paul Oyer, author of Everything I Ever Needed to Know about Economics I Learned from Online Dating. Historian Moira Weigel, author of Labor of Love, explains how dating and commerce have always been intertwined, and Eric Silverberg, CEO and co-founder of Scruff, a dating app for gay and bisexual men, argues that dating apps are doing more than just selling romance.
