Hiroshima's trees of hope

When an atomic bomb was detonated over the Japanese city of Hiroshima in 1945, hundreds of thousands of people were killed and injured. Despite many survivors believing nothing would grow in the city for decades, 170 trees survived close to the epicentre and are still growing 75 years later. Green Legacy Hiroshima is a project which sends seedlings from those trees around the world, spreading a message of hope. Rachael Gillman has been speaking to Teruko Ueno who survived the bombing of Hiroshima, and her daughter Tomoko Watanabe who is a co-founder of the project.Photo: one of the trees which survived the atomic bomb.
