Iraqi-American pediatrician Dr Mona Hanna-Attisha has played a critical role in exposing the water crisis in Flint, Michigan, which affected thousands of adults and children after dangerous cost-cutting measures led to widespread lead poisoning.

This week, we speak with Dr Attisha about her new book “What the Eyes Don't See: A Story of Crisis, Resistance, and Hope

in an American City,” which centers on her own account of the crisis through both scientific and activist lenses.

Later in the program, Italian director Marco Proserpio will tell us about the making of his documentary film “The Man Who Stole Banksy” ,

which chronicles the saga of one of street artist Banksy’s murals in the Palestinian city of Bethlehem and how it ended up on the western world's commercial art market.
