It’s just over a year since the UK’s trading relationship with the EU fundamentally changed. So how are small businesses in Britain finding life outside the single market and customs union? The BBC's Vivienne Nunis speaks with chocolate-maker Jacques Cop of Coco Caravan and Kathleen May from the London-based independent publisher, Hurst, as well as Sally Jones, trade strategist at EY.

Why can't multinationals like KFC source their ingredients locally? A shortage of fries at KFC restaurants in Kenya has led many to call for a boycott of the chain after it transpired that the company imported all of its potatoes, despite them being abundantly grown in the country. Potatoes are Kenya's second-most consumed crop after maize, and are cultivated mostly by small-scale farmers. As Covid hits global supply chains and words like sustainability and climate gain greater importance, is it time for multinationals to start looking closer to home for their goods? Kathambi Kaaria is a climate change and sustainability advisor in Nairobi and comes from Meru, a potato growing region of Kenya. She told Tamasin Ford that when KFC arrived in the country eleven years ago she tried to supply them potatoes. Leonard Mudachi, the CEO of a Kenyan restaurant management company Branded Restaurants Africa Ltd, said he wasn’t surprised to learn that KFC imports its chips but does think that multinational companies should start scrutinizing how and where they get their produce from. John Quelch is the Dean of the Miami University Herbert Business School in the United States. He told Tamasin that the issue for a major international brand is the quality and consistency of locally sourced produce and that one mistake by one supplier can lead to a massive fallout for the companies.

How might the protests shake up the economy, trade and business in the Central Asian nation?

Ed Butler speaks to Diana Kudaibergenova, a sociology professor at Cambridge University and herself Kazakh, about what motivated the protests, and whether the apparent ouster of former President Nursultan Nazarbayev plus a host of new economic reforms will be enough to appease the protesters.

But what does all this mean for foreign business interests in the country? Kate Mallinson of Chatham House says many Western oil executives will be having sleepless nights, while Russia's President Vladimir Putin may require an economic dividend for his military help in stabilising the situation.

And what of Kazakhstan's other giant neighbour, China? Raffaello Pantucci of the Royal United Services Institute says the upheaval has come at a time when many Kazakhs were questioning the seeming one-sidedness of their increasingly close economic ties.

Does the global economy need to start dismantling 'global white privilege'? The Black Lives matter protest movement has focussed lots of attention on racial attitudes in rich western countries. How easy is it for instance, for people of black or Asian heritage to get on the ladder to business success in those countries? But is the economics of what's now called 'white privilege' a global problem too? Ed Butler speaks to Chandran Nair, the founder and Chief Executive Officer of The Global Institute for Tomorrow, an independent think-tank in Hong Kong and the author of ‘Dismantling Global White Privilege: Equity for a Post-Western World’. And also to Lucinda Platt, from the London School of Economics, who has recently written a report for the IFS on the degree of social and economic mobility being achieved among the UK's minority racial and ethnic groups.

Psychedelic therapy could provide a major breakthrough in the treatment of mental health disorders like depression, and now it's caught the attention of start-ups and venture capitalists.

Laurence Knight hears from one man whose life was transformed by a single dose of the drug psilocybin - the psychoactive ingredient in magic mushrooms - after he volunteered for a research project exploring whether it could cure depression. He also visits the research team at King's College London, who have just wrapped up the latest trials of the drug.

The trials are being sponsored by the healthcare start-up Compass Pathways, and its founder and chief executive George Goldsmith explains why he hopes to use them to bring this therapy to the general public. Plus Amanda Eilian of venture capitalists Able Partners describes how quickly attitudes in the investor community are changing.

On this edition of Business Weekly, we’re looking at the tech giant Apple. Its value tipped over the $3 trillion mark on the New York stock Exchange at the start of the year. We hear from Dan Ives of Wedbush Securities on possible further avenues of growth for the company. We’ll take you to the United States to hear from different communities all hoping to benefit from President Biden’s $1.2 trillion infrastructure plan. We focus on projects designed to improve the quality of drinking water, and public transport. The BBC’s Will Bain covers examples from Alaska, Michigan and California. Plus, we remember the work of the world renowned Kenyan paleoanthropologist Richard Leakey, who died at the start of the year. We hear from Dr Paula Kahumbu who knew him from childhood, and now runs one of the organisations he founded. Business Weekly is presented by Sasha Twining and produced by Clare Williamson.

Mapping the human genome led to big advances in diagnosing rare disease. But diagnosis is only the first step in dealing with an illness. So what do you do if your child is found to have a condition that has no treatment? We hear from Michelle Teng, a mother who co-founded a biotech firm called SynaptixBio, that is looking to find the world’s first treatment for a rare neurodegenerative disease. Also in the programme, the Chief Medical Officer at Genomics England, Dr Richard Scott, tells us his hopes for the future of genomics medicine. And Dr Segun Fatumo of the London School of Hygiene and Tropical Medicine, explains why Africa is so important when it comes to genetic research.

The rise of electric vehicles could see traditional service stations closing across the planet over the next two decades, and replacing pumps with fast chargers is unlikely to save them.

Justin Rowlatt speaks to one entrepreneur hoping to profit from the rollout of EV chargers in every home and parking space, Erik Fairbairn of Pod Point. Meanwhile Isabelle Haigh, head of national control at the UK's National Grid, explains why she is confident they can meet the electricity demand from all these new vehicles.

Across the Atlantic, another entrepreneur - Sanjiv Patel of National Petroleum - says the writing is clearly on the wall for his chain of 25 gas stations in California - but maybe not for a while yet. But could he turn them into restaurants or use them to hold séances? That's the fate of one petrol station in Leeds that is now an arts centre. We hear from its owner, Jack Simpson.

This is a repeat of an episode first broadcast on 2 June 2021.

Richard Leakey died at his home outside Nairobi, Kenya, earlier this week. World-famous for his fossil discoveries, the 77-year-old had many careers - paleoanthropologist, wildlife defender, politician and anti-corruption campaigner. Business Daily's Vivienne Nunis met Richard Leakey late last year and recorded this interview with him. He looks back on his life and shares his as yet unrealised plans for a 'cathedral of life with no God', a museum dedicated to evolution on the edge of Rift Valley.

Jane Goodall, the famous primatologist, has set us a challenge: Is it possible to tackle climate change whilst also lifting people out of extreme poverty?

Her question - posed to the BBC's Climate Editor Justin Rowlatt - is inspired by her own experience of tackling deforestation in Tanzania. As her colleague Emmanuel Mtiti explains, they convinced local villagers to stop felling trees, and to restore the natural habitat of chimpanzees, by offering them an alternative path to prosperity.

So could an equivalent path be available that avoids increasing carbon emissions? If so then it would break with the pattern seen in Europe, America and China, where economic development was almost entirely fuelled by burning coal, oil and gas, according to Hannah Ritchie, head of research at Oxford University's Our World in Data team. But the micro-finance pioneer Muhamad Yunus says that solar power does now offer a carbon-free way forwards.

The programme contains audio from the 1965 National Geographic documentary film Miss Goodall and the Wild Chimpanzees, as well as audio recorded at Gombe National Park and the surrounding area by Ruth Happel and Bernie Krause.

Most flowers sold in the florists and supermarkets of Europe are grown in East Africa, where the warm climate supports roses and other plants to grow year round. But is it sustainable? Vivienne Nunis follows the international supply chain from a Kenyan flower farm to the hub of the global flower trade near Amsterdam, where every morning stems are sold at auction before being transported in cold storage trucks to buyers across Europe. The Dutch have been trading flowers since medieval times, when speculators paid enormous prices for tulip bulbs. We pay a visit to Amsterdam's Tulip Museum to find out why. The worldwide flower market is worth $40bn a year, but as growing numbers of consumers start to question the true environmental cost of what they buy, some growers are advocating for a return to seasonal, local blooms.
