Earth Hour Photos

If you live in Sydney, you may have heard of EarthHour - an hour of lights out. It got a little bit of publicity in other areas of Australia - but not much. In Sydney, tens of thousands of households and companies got behind it.

You've heard of "before and after" photos ... well these are more like "before and during"....



While the Earth Hour itself saved tonnes of greenhouse gases, the main idea is to create awareness of climate change, and how we can make a difference.
