Lights off at 8.30 tonight
And keep the cause alive beyond it, urges Vidya Balan in support of the Earth Hour campaign.
Vidya Balan wants you to turn off the lights. The actor, 33, has urged youngsters not just to switch off lights during WWF’s Earth Hour 2011 campaign, but to go beyond the hour to protect the earth from the perils of climate change.

The Earth Hour will be observed today at 8.30pm, when the world will pull out the plug on lights and other electric appliances to show solidarity in energy conservation.
"As the effects of climate change become more powerful, it is up to each one of us to take ownership of our collective future. It is inspiring and encouraging to see how a step as simple as switching off lights for an hour can unite the entire world towards a cause. I, too, switched off lights last year, and will do so this year as well," said Balan, who will be soon seen on the big screen as Silk Smitha.
The actor also added a plus sign to the ‘60’ logo of Earth Hour. The plus signifies a commitment to the cause beyond the 60 minutes of the

campaign’s run itself. "I pledge to go beyond the hour. To be mindful of conserving resources, everyday, not just for an hour. And urge you to do so as well," she says.
Over one billion people in more than 6,000 cities across 130 countries around the globe are expected to join the initiative today.
