Earth Hour

Did you know that more than 10,000 people and 450 companies in Singapore have pledged to "switch off" for one hour from 8.30pm (28 March) to mark Earth Hour? It is the global initiative by the World Wide Fund for Nature (WWF) to raise awareness about climate change and global warming. Famous local landmarks such as the Merlion, the Singapore Flyer, the Underwater World in Sentosa and Changi Airport are showing their support. At least 2700 cities in 84 countries around the world have committed to mark Earth Hour. Do you know what it is all about? Read up about it! Watch it here!
