What began as a WWF Australia project to focus public attention on climate change has turned into an international movement that has become the largest voluntary action ever witnessed, reaching 1.3 billion people across the globe.
According to WWF India, in this country with a population of 1.22 billion where I happen to live, 5 million citizens in 58 cities participated in Earth Hour 2009.
In 2010 the numbers grew to 7 million participants (including 600,000 students) in 128 cities.
In 2011 more citizens in more cities joined in the environmentalist movement, including Chief Minister, Smt. Sheila Dixit switching off lights at India Gate at 8:30 along with Brand Ambassador Vidya Balan.
And in 2012? The challenge is out. But Inmans in India and Ithaca plan to participate.
