What started as an event in Sydney, Australia is now a global movement. Last year nations all round the world heeded the call to switch-off lights against global warming.

This year, let’s make it bigger. Now is another chance to make a difference.

Tell your friends to take part in Earth Hour 2009 by switching off lights for an hour on March 28, 2009 Saturday from 830 PM to 930 PM. With the meeting of world leaders in December 2009 in Copenhagen this action will send a strong message on tackling climate change issues.
