When the atomic bombs were dropped in the cities of Nagasaki and Hiroshima in 1945, thousands of people died immediately. Thousands more died in the years that followed, from radiation sickness and cancer. One famous example is Sadako Sasaki, a two year old at the time of the bombing, who died of leukemia ten years later. Having heard a Japanese folktale, Sadako tried to fold 1000 paper cranes, in order to have a wish fulfilled. She died before she finished, but every year, tens of thousands of school children around the world read the story written about her, and fold 1,000 cranes. Many of these cranes are sent to the Peace Parks in Nagasaki or Hiroshima and are displayed there.
