As the lights went out at 10 p.m. on Sunday night, the glow of awareness spread around. The theme was the fight against global warming, and darkness was used as a means to spread light.

Participating in an event at Anna University organised by Exnora International to mark the ‘5 tens Lights Out campaign' here on Sunday, Deputy Chief Minister M.K. Stalin asked the youth to understand the consequences of global warming and to make choices that “will benefit the world”.

Launched in 2008, this is the third edition of the lights out campaign. The central aim of the campaign is to spread awareness about global warming and the need to reduce energy consumption. Last year's campaign was organised at the Ripon building.

Switching off the lights to signify the culmination of the year-long campaign, he said “Many of the lessons that I have learnt about the environment have been through campaigns like this. Switching-off lights is symbolic, but it gives an opportunity to talk about issues such as global warming and climate change.”

Mayor M. Subramanian said that most people had understood the problems associated with global warming and government initiates, such as the recent move to ban incandescent bulbs from government offices, was aimed at tackling the problem. Anna University Vice-Chancellor P. Mannar Jawahar and Exnora International founder M. B. Nirmal spoke.
