Every year since 2008 people across nations turn their lights off for an hour on the last Saturday of March to show support for the need to take action against climate change. The event is known as Earth Hour.
It was 2009 and I was disappointed that my home town, Burgas, had not participated the year before in the global climate change awareness movement. I wanted to bring the event home. At the time, I was a member (later elected a president) of Interact club Burgas Primorie, a Rotary club chapter for youth. I led ~15 of my fellow members at Interact to engage city council official, local businesses and non-profits. We organised an hour-long programming of fire shows, step dancing, live music and business and local government turned their lights off in a sign of support in 2009, 2010 and 2011 (these are years during which I was involved; the event went on afterwards).
