The song 'We Are Walking On', released by the United Nations, is definitely a must-listen composition on the World Environment Day. Not only because of its music and lyrics, but also due to the personal story of the creator of this composition Sadaharu Yagi. The United Nations itself has said that memories associated with Sadaharu's childhood have been an inspiration behind this song.
Sadaharu’s childhood was spent in Japan’s Kitakyushu, which was the most polluted city in the 1960s and the air was not fit to breathe.
