The bodies of 39 Vietnamese men and women discovered in a lorry container in Essex highlighted the growing problem of illegal and dangerous journeys into the UK. With police and governments pledging to do more to uncover illegal smuggling operations Radio 4 speaks to refugees, lorry drivers and to some of the smugglers behind this deadly trade

Recent coverage from Greece has highlighted the pressures on borders as desperate people risk everything to cross from Turkey. Dangerous Trade starts by tracking a dinghy full of refugees landing on the island of Lesbos and heading for the now infamous Moria camp. It was constructed for 3,100 people but now has a population of more than 20,000 men, women and children.

On the camp refugees speak about their dreams of a new life and many hope to make it to the UK. Following the route of some of those that have, Sue Mitchell joins them in Dunkirk as they negotiate with smugglers and weigh up the risks of crossing the Chanel illegally by boat or stowing away in lorries bound for England.

Those who make the crossing know they are lucky to have survived. The deaths in the Essex container lorry revealed the shocking risks – as do reports of others who have perished at sea and on land. For the lorry drivers who inadvertently end up smuggling refugees, there’s growing anger that more isn’t being done at the borders. Governments have promised to work together to tackle this growing problem, but solutions are still a long way off.

Everywhere she goes, people ask for selfies and tell her how wonderful she is. But what’s it really like to be the world’s most famous climate campaigner when you’re still a teenager? In this revelatory personal essay which she wrote for Swedish Radio, Greta Thunberg describes her journey to deliver a speech at the UN General Assembly, observing the effects of climate change first-hand, her encounters with both powerful and ordinary people and a terrifying trip in a yacht across the Atlantic.

This Swedish Radio production is introduced by Justin Rowlatt, the BBC's chief environment correspondent, and Greta's essay is interspersed with excerpts of her favourite music.

Nearly two million people are now known to have applied for Universal Credit since the start of the Coronavirus lockdown. For many of them it’s their first time, and is in sharp contrast to how they expected their lives to be.

Shark, bear and crocodile attacks tend to make the headlines but humans fall prey to a much wider variety of predators every year, from big cats and snakes, to wolves, hyenas and even eagles that’ve been known to snatch the odd child. The details can be grim and gory as many predators have developed specific techniques for hunting us humans down. But it was always so, as biologist Professor Adam Hart discovers. Archaeological evidence suggests early hominins in Africa were more hunted than hunter, spending much of their lives scavenging for food and fending off attacks from the likes of sabre-tooth-cats and giant hyenas. Much more recently, legends abound about some of the more infamous serial killers of the animal kingdom, such as the 'man-eaters' of Tsavo and Njombe - the latter, a pride of about 15 lions in Tanzania who, it is claimed were responsible for an astonishing 1500 deaths between 1932 and 1947.

Today, estimates and sources vary but most suggest carnivorous predators are responsible for hundreds if not thousands of human deaths every year. But how much of this is active predation and how much is mistaken identity or sheer bad luck? Adam speaks to experts in human-wildlife conflict dedicated to reducing attacks on both humans and predators in Africa and India, where the tensions between protecting agricultural interests and preserving predator habitats are most problematic. He discovers the grim reality for many poor rural populations dealing with the sharp end of living in close proximity to large carnivores and discusses the potential solutions for driving down attacks on both humans and predators that are caught up in the struggle for survival. Closer to home, Adam meets a wolf-tracker, who helps to monitor wild wolf populations that have spread up through Italy and France, attacking livestock with increasing confidence. Could humans be on the menu next?

Gordon Corera asks if the West is losing the technological race with China. Why did the decision to let the Chinese company Huawei build the UK’s 5G telecoms network turn into one of the most difficult and consequential national security decisions of recent times? A decision which risks undermining the normally close special relationship between the US and UK? The answer is because it cuts to the heart of the greatest fear in Washington – that China is already ahead in the global competition to develop the most advanced technology. Some people ask how we have got to a position where the West needs to even consider using Chinese tech. The answer may be because they failed to think strategically about protecting or nurturing their own technology industry over the last two decades. A free-market system has faced off against a Chinese model in which there is a clear, long-term industrial strategy to dominate certain sectors of technology, including telecoms, quantum computing and artificial intelligence. This is a rare issue where the US national security community – the so-called ‘Deep State’ – is in close alignment with President Trump. Now the US and UK, among others, are scrambling to try to develop strategies to respond and to avoid dependence on China. But – asks BBC Security Correspondent Gordon Corera – is it already too late?

When football introduced the Video Assistant Referee, better known as VAR, fans thought it would cut out bad refereeing decisions but, as we limp toward some conclusion of this Covid-19 interrupted season, many now want to see the pitch referee back in charge.

Today there's a booming wellness industry, including luxury spas and hotels as well as personal trainers and supplements, claimed to be worth over $4 trillion a year. Online at least, self-care seems to revolve around buying stuff – luxury oils, face creams, scented candles, face rollers, bath bombs, silk pillows, cleansing soaps and stress-relieving teas. Or we can cherish ourselves by paying someone else for a service, from a yoga session to a delivery of artisan chocolates.

With the help of the archives Claudia Hammond explores where the idea of wellness came from. She discovers its roots in the WHO's definition of health and in the counter culture of California in the 1960s, when the residents of Marin County took to hot tubs and peacock feathers. Claudia looks at the thorny relationship between wellness and medicine and those who look after or study our health. There's a Wellness Newsletter that has been produced in Berkeley since 1984 that weighs up the scientific evidence for and against new treatments, and many doctors offer complementary therapies alongside conventional medicine. Yet there is no published research to support the benefits associated with some wellness products.

The coronavirus outbreak revealed an international shortage of ventilators. Across the world, govenrments scrambled to acquire new ones, not just from traditional manufacturers, but from anyone who though they could design a simple yet functional device. As a result, hundreds of teams and individuals have risen to the challenge, including university students and hobbyists. Jolyon Jenkins set out to design and build a ventilator himself, drawing on the wealth of shared informationi and designs that have emerged in the last few weeks. He soon discovers that it's harder than it looks.

Much publicity has gone to organisations that have produced ventilators that are not up to standard. And as knowledge of the disease has progressed, it's become clear that coronavirus patients need very careful and specialised forms of ventilation if it's not to do more harm than good. So are non-specialists capable of producing machines that will actually benefit patients?

Susan Bright gets bloody and fleshy with sculptors, performance artists and filmmakers who use animal parts as their raw material.

Images of meat in still life paintings have been a staple in art for centuries, but why are artists now incorporating animal flesh, offal and skin into their work. What draws them to this macabre material and what does it enable them to say?

Photographer Pinar Yolacan makes meat dresses for her models, frills from raw chicken, bodices from placenta and sleeves from tripe. Riffling through butchers stocks, she makes the perfect outfit for her models, designing and moulding it to them like a second skin.

In a high-vaulted church, Elpida Hadzi-Vasileva hangs gigantic curtains of white pigs fat that look like long sheets of lace. Walking down through them, they rustle and reek as you feel encased inside an animal’s stomach.

Oron Catts and Ionat Zurr sculpt with live tissue making a semi-living leather jacket, growing wings from pigs and hosting a dinner party with lab grown meat. While Marianna Simnett violently slices open a cow’s udder reorganising our thinking about the body and gender. And with a cast of 100 performers, Hermann Nitsch's theatrical performances involve climbing inside carcasses, bathing in blood and having sex with offal.

Their work is shocking, disturbing and fun, making us face our responsibility to animals, each other and the planet and giving us a language to talk about the challenges ahead.

We lick our lips and feed on their creativity.

Tracking the virus hunters who race to understand and extinguish new pathogens. Sars Cov 2 is the virus responsible for the pandemic of 2020. But there are millions of other viruses living around the world, any one of which could mutate and infect us at any time. Scientists are in a never-ending race to identify these viruses and contain their dangerous effects. Oxford Professor Trudie Lang, director of the Global Health Network, hears from some of the virus hunters who work against the clock to research and combat these threats. Fighting epidemics requires effort from across the scientific spectrum. What we learn from the outbreak of Covid-19 will be crucial beyond understanding this coronavirus, but also when the next Virus X comes - and it will come.
