The organizers of the Earth Hour have been expecting more than one billion people around the world to take part in its next campaign scheduled on March 27.

Earth Hour is an initiative by the World Wildlife Fund which originated in Australia in 2007, wherein 2.2 million homes and offices in Sydney had turned off their lights for one hour, to mark the need of curbing the climate change.

In 2008, the day was marked globally. On March 27 the various participants are expected to turn off their lights at 8:30 pm local time.

The program is basically aimed at highlighting that there is still a possibility of saving the environment which only requires awareness within every individual.

For this year, around 105 countries have confirmed their participation.

“The huge success of Earth Hour shows that Canadians are ready to take action on climate change”, said Gerald Butts, president and CEO of WWF Canada.

He further said more than 10 million people had participated in the move last year. Around 5% of them were adult Canadians.

In 2009, hundreds of millions of people turned out their lights for one hour to show their support for climate action. In Canada, an estimated 5% of adult Canadians participated.

Earth Hour 2010 will be a greater event winning more and more public interest.
