"For Earth Hour 2011, I pledge to not just switch off but to go beyond the hour. To be mindful of conserving resources, everyday, not just for an hour. From this year on, I pledge to use energy smartly. And urge you to do so as well. Each one of us has the power to make a difference. We just need to be conscious of it and make wise choices. When each of us take simple steps, together these actions add up. I am supporting the fight against climate change by adopting some of these steps. It's time you do too." REUTERS
