At 830pm on Saturday 28 March, Sydney will be plunged into darkness as the city turns off its lights and embraces EARTH HOUR.

EARTH HOUR is a call to action against global warming and climate change by encouraging people all over the globe to switch off their lights and convince decision makers to take immediate action to save our planet.

So why not join the expected one billion people who will take up the call and Vote for Mother Earth on 28 March?
