It is a movement that started right here in Australia about four years ago, aimed at raising awareness of global climate change and what one can do to combat that change. What you do is very simple - at 8.30pm today (Saturday 26 March), turn off all the lights in your house for an hour. I tend to go that one step further and turn off all electrical equipment, which means TV, laptop, stereo etc. (except for the fridge of course!).
The mere action of turning off the lights is definitely not going to change anything drastically, but Earth Hour is more about the awareness of climate change and what one can do beyond this one hour.
My challenge tonight will be to try and take a picture of whatever we're going to do and to scrapbook that. This means definitely getting out the tripod and hoping that there will be enough ambient light (from our lovely gas fireplace and maybe a couple of candles) to light up whatever we will be doing.
Will you join me?
