We continue listening back to some of the most memorable stories we’ve aired. Today, Producer Phoebe Judge visits the Ganges River, one of the holiest yet most polluted places in India, and meets people who want to clean it up. Also in this show: Arun Gandhi was 10 years old when he was beaten up and bullied because of the color of his skin. He wanted revenge, so his parents sent him to spend time with his grandfather Mahatma Gandhi; and for more than 25 years, few people have been allowed to enter the 1,600-square-mile Chernobyl Exclusion Zone. Writer Henry Shukman tells the story of a family who returned there.
