New York: UN Secretary General Ban Ki-moon leads a host of world and civic leaders supporting Earth Hour 2011 as a powerful symbol of a shared wish for a sustainable and secure future. “All over the world individuals, communities, businesses and governments are creating new examples for our common future – new visions for sustainable living and new technologies to realize it,” Ban Ki-moon said. “Tomorrow, let us join together to celebrate this shared quest to protect the planet and ensure human well-being. Let us use 60 minutes of darkness to help the world see the light.”
