In the 1990s, as oil spills devastate the environment, Shell becomes persona non grata in Ogoniland. Then, when Ken Saro-Wiwa, Ledum Mittee and other activists leading the charge against Shell, are accused of incitement to murder, they come face to face with the power of Nigeria’s military government.

BBC West Africa correspondent Mayeni Jones investigates a miscarriage of justice which has become an infamous moment in Nigerian history.

When oil company, Shell D’Arcy first struck black gold in Nigeria, there were celebrations on the creeks of the Niger Delta. Many of the locals had no idea what this thick black substance was, but it would go on to shape their lives and those of everyone in the region for decades to come.

BBC West Africa correspondent Mayeni Jones hears about how hope and hospitality turned to resentment in the early days of oil in Nigeria.

Psychiatrist Henrietta Bowden Jones talks to June Angelides about how she set up Mums In Tech on maternity leave, and how she was inspired by her entrepreneurial family in Nigeria, and particularly by her late grandmother. June reveals why she gave up a good job to set up the first coding academy in the United Kingdom for young mothers. And talks about the stress it caused but also knew that the time was right for her to do this.

Halima Begum is the CEO of the race equality think tank The Runnymede Trust. Her career as a civil rights campaigner began when she formed Women Against Racism in 1993, which was forged by her experiences of being racially abused by the National Front every day she went to school in East London. She reveals just how her mother coped with the threats that the family received on a daily basis. And it how it contrasted sharply with the welcome and love that Halima received from the teachers in her local school.

Her parents had already known conflict in their homeland, as Halima was born two years after the brutal civil war between Bangladesh and Pakistan, which traumatised many Bangladeshis. She tells psychiatrist Henrietta Bowden Jones how those experiences have shaped her life and opinions.

Musician Maya Youssef talks about her painful decision not to return to her parents' house in Damascus when the civil war in Syria began. She reveals how playing music brings back such vivid memories of her homeland that she feels she has returned to her birthplace, even though she has not been there for over a decade.

Psychiatrist Henrietta Bowden-Jones talks to novelist Dina Nayeri about her experience of escaping Iran and seeking asylum. The author of The Ungrateful Refugee reveals why she left her homeland without her father, her "co-conspirator in life", and why that sense of loss that has always stayed with her.

When noise levels rise, birds react. Noise is one of the top environmental hazards to which humans are exposed. It has also been linked to reduced breeding success and population decline in birds. So what happened to birds during the coronavirus pandemic lockdown when our cities fell silent? Many people said they could hear birds as they were singing louder. Did their singing change and if so, how and why? What can we learn about noise pollution and its effects on us from the birds?

Just like us, birds can become infected with viruses – and some of these can be transferred to us. As we’ve seen with the coronavirus pandemic, there are real challenges when it comes to controlling the spread of viral infections. Any attempt to try and stay one step ahead of a virus requires really good monitoring, especially as many birds travel long distances and migrate. Birds are invaluable as sentinels in our attempt to map and control the spread of infection. In this episode we look at how water birds, poultry, jays and sage grouse have alerted us to the spread of diseases which affect them and us in the environment.

How the deaths of vultures and sparrowhawks have alerted the world to serious environmental problems. Like the canaries which were used to detect toxic gases in coal mines, birds play a vital role in alerting us to substances which can damage a healthy environment. The price they pay to alert us can be losing their lives.

Many of today’s old people grew up in an era when life was hard, retirement short, and opportunities for play limited. But as we live longer, we need to seek out playful activities, for both physical and mental health.

We visit a bridge club for older people, where many members started to learn the game after they retired, to keep their brains sharp and give them social opportunities. We visit a care home in Scotland where the management frequently organise play sessions, such as pretend weddings, and where disco bingo is a regular event. And in Jerusalem, we meet two older men, one Arab, one Jewish, who come together over a shared love of backgammon. But will the old people of tomorrow want to move beyond these traditional games, and if so, what will the play of the future look like?
