Earth Hour 2012, will be held on Saturday March 31st, 8:30pm to 9:30pm
What is Earth Hour?
Earth hour is a global movement, that brings together individuals, colleagues, communities and people from across the world, who celebrate a commitment to the planet by switching off lights for one designated hour.
Last year's Earth Hour took place in 5251 cities in 135 countries across all seven continents, joined by 1.8 billion people. Hope that this year would be even bigger!
Let us save the Mother Earth!
