Parts of China and Korea flipped off the power as Earth Hour swept over the two countries, all in an effort to save energy. In Beijing, the iconic Forbidden City was pitch black as thousands of people watched on.
It was quite the spectacle in Taiwan as the lights in the world's second tallest building went out for one hour. Hundreds of people watched as the lights of Taipei 101 went into complete blackness. Crowds rallied in the streets and lit candles in the city hall square.
Participants in Taipei said that 'The country's global warming awareness is growing and simple habits can make a huge difference.' One 21 year old Taipei resident said, 'For the earth to live longer, we have to work together to make it last.' 'These small things are easy to do, and I hope everyone can participate' said another person.
The gathering was organzied by the Society Wilderness, an environmental organization that functions as a branch for the World Wide Fund for Nature (WWF).
Meanwhile, The Philippines marked Earth Day by switching off two shopping mall parking lots in the country's capital of Manila. Although it was a small gesture, co-event organizer Catherine Maceda said, 'Climate change is here with us. It's going to stay with us. I think the challenge for us is to do something about it in terms of slowing down.'
The event began in Sydney in 2007 and has since become an international event.
