When Megan Garcia travelled to Rome, she carried with her a mother’s grief. At the Vatican she met the Pope and asked him to pray for her son Sewell, who died last year at the age of 14. In the months after his death, Megan discovered Sewell had been spending hours talking to an artificial-intelligence chatbot, which he believed was a real person for more than a year. He formed a deep emotional attachment to it, confiding in it about his life and feelings. Megan believes that relationship played a part in her son’s death. She is now pursuing legal action against the company behind the chatbot, arguing that safeguards for young users were inadequate. The company disputes the claims. But rather than losing her belief, Megan turned to prayer and devotion to the Virgin Mary, finding comfort in the idea of a mother who also knew the pain of losing a child. This episode of The Documentary, comes to you from Heart and Soul, exploring personal approaches to spirituality from around the world.

In India's Gujarat state lies the Little Rann of Kutch, a sprawling salt marsh desert where temperatures soar to 50 degrees Celsius. This harsh landscape is home to the Agariyas, nomadic tribal families who have harvested salt here since the 16th Century. For eight months of every year, they migrate to this harsh environment, living in temporary shacks and pumping briny groundwater into vast pans where it evaporates into gleaming, sturdy crystals. This traditional practice, responsible for 75% of India's salt production, is now under a grave existential threat. Seasonal cycles, predictable for centuries, have become erratic. Unexpected rains and sudden cyclones frequently wash away months of intensive labour, leaving families in mounting debt. Despite providing an essential global commodity, these workers earn three percent of the salt's final value, living without running water or basic sanitation.

Hope emerges through innovation and activism. Scientists at the Central Salt and Marine Chemical Research Institute are introducing new types of pan linings and solar-powered pumps to reduce costs and increase yields. Activists like Pankti Jog fight for land rights, healthcare and education, establishing mobile schools in old buses for the next generation. Yet, the future remains a gamble. While some children dream of becoming teachers or police officers, many feel tethered to the salt by heritage and lack of choice.

Stephanie was brought up in France in a French family, but her birth parents are Indian – she’s an intercountry adoptee. In the 1980s and 1990s thousands of babies, like Stephanie, were adopted from India into white, western families. Now, inter-country adoption is more regulated, and there’s a recognition that this is a practice open to abuse – several countries have banned it altogether.

In France, Stephanie grew up very happily with her adoptive mum and dad. But after they both died, she began to think more about her origins. And she experienced a desire to re-connect with her motherland. In this edition of Assignment, Stephanie journeys into rural India in the state of Maharashtra with journalist, Tanya Datta. Together they attempt to find Stephanie’s birth mother. Along the way, Stephanie discovers she isn’t an ‘absolutely abandoned and destitute child’ found on the roadside as she’s been led to believe her whole life, but was born to an unmarried teenager. Nearly 40 years later, will she find that 50-something woman?
